Thank you for purchasing the Precise®SHP Soft Tissue Diode Laser.
The Precise SHP Diode Laser System perfectly combines state-of-the-art diode laser technology with the
cutting-edge operating system of an iPod touch®. It is the first diode laser system with an iPod touch
interface to receive FDA clearance for a variety of treatment procedures. The Precise SHP is also the first
diode laser system in the industry to include sterilized tips.
The revolutionary Precise SHP enhances everyday dental procedures with real-time technical support
through FaceTime at the iPod touch of a button. The Precise SHP’s versatility extends beyond soft tissue
surgical procedures and allows the practitioner to offer laser therapy for temporary relief of muscle and
tissue pain relating to dental and oral procedures, as well as in-office, laser assisted teeth whitening.
CAO Group (CAO) has been manufacturing high technology diode lasers for more than a decade and
we are proud of our record of quality, performance and safety.
The Precise SHP uses laser energy at a wavelength of 810nm to cut or ablate soft tissue. The 810nm
wavelength is optimally absorbed by oxyhemoglobin and melanin, and to a lesser extent by water.
In addition to these actions, 810nm laser energy is found to have an advantageous effect on wound
healing, pain reduction and accelerated hemostasis. This wavelength of energy is not absorbed by bone
or hard tissue and should not be used on these materials. The laser energy is generated within the Base
Module of the system and transmits through the handpiece tubing to the handpiece tip. The laser energy
is then transmitted through the air to the patient’s tissues.
To help speed your implementation of the Precise SHP into patient treatment, CAO has developed the
Precise Quick Start online video program to enable easy setup of the Precise SHP so that it is ready to
use the day it arrives. Also included in the video is a review of the basics of using the Precise SHP so that
you can develop familiarity with the unit and its operation, as well as trying initial or basic procedures.

2.5. Locating the Precise SHP for
Delivery Unit Use
The Precise SHP Base Module is designed to be mounted
to a cart or counter and the handpiece and display
conveniently located among other instruments and
equipment. It may also be setup as a countertop unit that
can be placed on a work surface.

8
2.5.1. Mounting Base Module to Delivery Unit
If desired, the Base Module of the Precise SHP can be mounted
to or within the operatory furnishings, or to carts or mobile
equipment. A mounting bracket (002-00231) is available
from CAO Group and is recommended for mounting the Base
Module suspended from an overhead surface. If needed, you
may contact your account representative or distributor for
assistance in mounting the Precise SHP within the operatory.
Ensure that the surface you are mounting to is flat and
strong, and able to support the weight of the Base
Module. The mounting brackets and hardware included
with the bracket kit will be used for the mounting.
1. Select the location where you want to mount the Base Module.
Make sure the location is close enough so the handpiece
tubing is able to reach the patient without stretching or
excessive strain. Make sure there is adequate space around
the Base Module for quick access to the power cord, remote
interlock (if desired), and display charging port. Make sure
the front of the Base Module is easily visible and accessible
so the indicator lights are visible, the power and laser stop
buttons are accessible, and the display charging connector
is accessible.
2. If you wish to mount the Base using screws,
proceed to Step #3. If you wish to use double-
sided adhesive tape (not recommended for wood
surfaces or curved surfaces), go to Step #7.
MOUNTING TO DELIVERY UNIT
3. Use the provided knobs to lightly secure the ends of the
mounting bracket to the bottom of the Base Module.
4. Position the Base Module to the underside of the surface
you want to mount it to. Use a pen or pencil to mark the
screw locations through the slots of the mounting brackets.
The distance between the screws is 2.0 inches from center
to center when using the center and side slots, and 1-1/8
inches when using the front and back slots.
5. Set the Base Module aside. It is recommended that you
pre-drill pilot holes or pre-attach the mounting screws
without the mounting bracket in place. This makes the
installation easier and often prevents cracking or splitting
of the mounting surface. With the holes made, position the
mounting bracket (separated from the Base Module) to the
underside surface so the holes are visible through the slots
in the mounting brackets. Screw in the mounting screws and
tighten securely.
6. Slide the base module into the bracket. Thread the mounting
knobs through the bracket ends and into the bottom of the
base module. Tighten the knobs to hand-tight.
DOUBLE-SIDED TAPE
7. Use the provided knobs to tightly secure the mounting
bracket to the bottom of the Base Module.
8. Use double-sided tape that is designed to permanently stick
to any plastic, laminate, or metal surface.
9. Remove the backing from one side of a piece of double-
sided tape and firmly press the adhesive onto the mounting
bracket. Repeat for the other piece of tape.
10. Ensure that the underside of the mounting surface is free of
dust and dirt, and is dry.
11. Remove the backing from the topside surface of the tape.
Position the Base Module just under the desired location,
then push the Base straight up until the tape contacts the
surface. Continue to press firmly for 5-10 seconds while
slightly twisting the unit side-to-side to ensure the tape is
fully attached to the mounting surface.
12. Slowly release your hold on the Base Module. Be prepared
to catch the Base if the tape didn’t adhere well. If the tape
fails to stick, repeat Step #11. If it still doesn’t stick, it may
be necessary to use the mounting hardware. Go to Step #3.
ALL MOUNTING METHODS
13. Once the Base Module is mounted, attach the power supply
cable to the back of the Base. If the operatory is configured
with a Remote Interlock (see Section 2.10), this should also
be connected at this time.
2.5.2. Mounting of Precise Display Module
The Display Module of the Precise SHP is an iPod touch® device
incorporating the Precise SHP Application touch screen system.
This Bluetooth enabled device allows the Display Module to be
mounted where it is most convenient for the operator while the
laser module is mounted under a work surface or otherwise out
of the way. The Display Module communicates via Bluetooth
technology with an effective range of fifteen (15) feet from the
Base Module. Each Display Module is uniquely paired with its
specific Base Module at the factory; no additional pairing is
required.
The Display Module can operate the Precise SHP either while
directly docked with the Base Module, attached to the charging
cable, or completely independent. Included in the kit is a support
stand that the Display can be placed in so it can be in a variety
of ways that is most convenient.

9
To mount the Precise SHP Display Module–
1. Remove the Display Module docking stand from the kit.
2. Identify a flat surface where you will place the docking
stand that is easy to reach but out of the path where
you access other instruments and materials.
3. Place the Display Module into the remote mount
holder.
4. Charge the Display Module (see Section 2.5).
An advantage of the iPod touch Display Module is that it
can be easily replaced if the original Display Module is
ever damaged. Simply call CAO’s Customer Care team
(877.236.4408) to order a new unit
NOTE: If a solid metal surface is between the Display
and Base, the Display may have difficulty
communicating with the Base. If this occurs,
reposition the Display so there are less items or
surfaces between it and the Base.
2.5.3. Setup for Countertop Use
The Precise SHP may be used as a countertop unit Identify
a secure location for the Base Module. Make sure there
is adequate space around the unit for quick access to the
power cord, remoter interlock (if used), and the docking
area. Place the Display Module in the docking area on the
Base Module.
1. Connect the power supply unit by plugging into the
adapter on the back of the Base Module. Connect the
power cord to the power supply unit and plug into an
outlet.
2. Attach the Remote Interlock connector if the operatory
is equipped with a Remote Interlock (see Section 2.10).
3. If desired, the mounting bracket (sold separately) may
also serve as a handle for the Base Module to facilitate
carrying the Precise SHP between operatories. Simply
slide the Base into the mounting bracket and secure the
ends of the bracket to the bottom of the Base using the
two thumb screws provided.
2.6. Charging the Display Module
In the upper right portion of the Display Module, the battery
status of the Display Module is indicated. When the battery
is low, the Display Module needs to be charged. This can
be done by placing the Display Module in the dock in the
front of the Base unit, or by attaching the charging cable to
the bottom of the Display Module and plugging the cable
into the charging port on the front of the base module.
The Display Module will not charge if the base module is
turned on.
2.7. Synchronizing (Wireless
Communication)
The Precise SHP system is designed so that only one iPod
touch can communicate or control one Base Module at any
given time. This helps to ensure that another iPod touch
or other wireless device in the surrounding area does not
inadvertently activate the Base Module. The connection
between an iPod touch and Base is made by synchronizing
the two to each other. When you receive your Precise
SHP kit, the iPod touch included with that kit needs to be
synchronized with the Base. If you have received a new
iPod touch for use with the Base, it will be necessary to
perform the synchronize function. Review Section 2.4.1.2
of the manual for detailed instructions on synchronizing the
iPod touch to the Base.
The Precise SHP utilizes the Bluetooth RF communications
available in the iPod touch® to communicate with the

as signal hopping. If other RF transmissions are detected and
compete with the Precise SHP communications, the system will
automatically hop to different channels to ensure uninterrupted
function. Additionally, the Display and Base communicate with
each other several times a second (cycle time of about 320ms)
to ensure accurate and up-to-date controls and commands are
processed. Because the transmitted data is comparatively small,
the entire display, command, and control status of the Base is
transmitted within the 320ms period. Thus any performance
anomalies that may occur within one transmission will be
corrected within the next transmission 320ms later. If more than
2 consecutive transmissions occur with incorrect or corrupted
data, the system will shut down and provide an indication of
wireless transmission malfunction. Thus you are sure the device
will work correctly at all times.
If for any reason communication doesn’t occur within 320ms,
the Base Module will interrupt any laser emissions that might be
occurring and exit from Ready status. The Display Module will
show a pop-up window indicating that communication has been
lost. Additionally, the blue indicator light on the front of the Base
will be off or blink slowly. If this occurs, wait for a few moments
to see if the Display and Base re-establish communications, or
reposition the Display if needed. If the blue indicator does not
illuminate, try running the synchronize procedure again. If this
still does not establish communication between the two, then
contact the CAO Group Service Department.
Despite these design features, this product may cause harmful
interference to other devices in the area that utilize the same
frequency and bandwidth. Similarly, this device may be
interfered with by other devices using the same frequency and
bandwidth. If interference occurs such that the normal use of the
Precise SHP or other equipment occurs, it may be necessary to
relocate either of these devices to different locations. Further,
it may be necessary to power off either the Precise SHP or the
other equipment in order for the other device to work properly.
2.8. Display Module (iPod touch®) Usage
The Precise SHP utilizes an iPod touch®as part of the system.
As an added benefit to you, the iPod touch maintains all of
the common features and capabilities you would expect for this
device. However, you are advised that any content or Apps
that are added/removed after taking receipt of the Precise SHP
system may adversely affect the performance of the Precise SHP
App. If you notice that such has occurred, it is recommended
that you delete or restore any recently changes to see if this
restores the Precise SHP functionality. CAO Group has taken
precautions in the design and testing of the Precise SHP system
to help ensure that the safety and effectiveness of the system is
maintained during use of this product. However, CAO Group
cannot anticipate all existing or future content that may be
added to the iPod touch, whether intentional or unintentional.
Therefore, you are advised to exercise judgment when using
the iPod touch included with the Precise SHP for purposes other
than operating the laser.
Judgment should be used when the iPod touch is removed
from the operatory. Only an iPod touch with the Precise SHP
App can operate the laser. The operator’s manual for the iPod
touch has been included with the Precise SHP kit. Any questions
about the use and functionality of the iPod touch, outside of
what is discussed in this manual, should be referred to the iPod
touch manual and its indicated support mechanisms. If you
have loaded an extensive amount of content or programs, it is
advised that you test fire the laser before proceeding with using
the system. See Section 3.3.2. Do not attempt to load other
Applications that purport to control lasers or medical devices.
The Base Module will only respond to the Precise SHP App
developed and issued by the CAO Group. Such foreign Apps
may cause undesired functions to occur and may expose the
operator or patient to unintended laser emissions.
CAUTION: Use only an iPod touch with CAO
Group’s Precise SHP Application with this product.
Use of other entertainment or phone devices and/
or use of other software applications may cause
unintended performance of the product, including
unintended exposure to laser radiation.
In the event that the Operating System (iOS) is
updated on the iPod touch, it is recommended that
you test all functions of the Precise SHP prior to
resuming use on patients.
NOTE: The iPod touch is used only to relay selections
to the Base Module and display the Base Module
status. The working beam cannot be activated by
means of the iPod touch. If any of the universal
settings on the iPod touch are changed, such as
changing the language setting, it is recommended
that you completely power down the iPod touch and
then turn it back on.
This ensures that the setting changes are fully
implemented and the Precise SHP Application
applies the new settings properly.

2.9. Power to the Base Unit
Remove the power supply and cord from the packaging.
Attach the power cord adaptor to the power supply
housing. Attach the power supply connector to the back
of the Base Module, as shown in Figure 2.11.
Plug the power cord into an appropriately rated outlet. To
prevent power surges due to electrical storms or spikes in
line voltage, we recommend that you use a power strip
with a surge suppressor or unplug the laser when you are
not present. In the USA, plug the power cord into a 110
Volt AC outlet rated at 60 Hz; for use elsewhere in the
world, make sure you use an appropriate adapter.
WARNING: Only use the power supply
provided in this kit, or indicated in the reorder
information in Section 9. Use of any other
power supply may create a risk of electric
shock to you or the patient, or permanently
damage the equipment. To avoid the risk of
electric shock, only plug the power supply into
an outlet that is protectively grounded.
CAUTION: Use of power supplies, cables, or
other attachments not specifically indicated
for this device may result in increased
electromagnetic emissions or decreased
immunity from electromagnetic energy.
2.10. Precise SHP Remote Interlock
(optional)
The Precise SHP is equipped with a Remote Interlock jack.
This enables you to establish a dedicated laser treatment
room where opening the entrance door of the treatment
room will automatically interrupt laser emissions anytime
the door is opened, to protect the eyes of the person who
is entering the room. We recognize that such installation is
not required or desired by some offices.
However, where desired, you may purchase an interlock
loop from a hardware or electronics store and plug it into
the Remote Interlock jack located on the side of the laser.
Inform the store that you require a mini (1/8”) phono
jack wired to a normally open momentary switch. Select
a switch design that will best fit your needs and ensure
there is enough wire to reach from the operatory door to
the location you intend to place the Precise SHP. To install,
mount the switch to the door such that the switch is released
when the door is opened, then secure the wiring as needed
and plug the phono jack into the side of the Base Module.
If no interlock is desired, this connector is already wired in
the closed position; no further action is required.
2.11. Foot Pedal Set-up
The Precise SHP system utilizes a foot-activated switch to
activate the laser beam. Review Section 4.2 of this manual
for instructions on installing the 9-volt lithium battery
provided with the kit. A lithium battery provides about 100
hours of usage before it needs to be replaced, and this type
of battery is recommend for the foot pedal. An alkaline
battery may be used, but will only provide about 35 hours
of runtime.
With the Base Module turned off, you can confirm the
functionality of the pedal and its battery by simply pressing
the foot switch. A blinking green indicator light will be
visible through a clear dome at the top of the pedal. If the
green indicator is not visible, press the reset switch adjacent
to the indicator window and try again. If the indicator light
still does not illuminate, then the battery should be replaced.
See Section 4.2 for the battery replacement procedure.

3. Operating the Precise SHP
3.1. Safety Considerations
The safe use of the Precise SHP is the responsibility of the
entire operatory team including the doctor, assistants, and
administrative staff. Protocols for the safe use of lasers have
been developed by a combination of medical and dental
professionals working in concert with educators at the university
level, scientists, and laser manufacturers. Sound judgment and
the concern for patient safety should be the basis of all laser
care. Below we’ve identified various safety considerations
that should be in place in the dental office and where more
information can be found in this manual:
• Access control and signage for the operatory. (Sec. 2.3.4,
2.4.6, and 5.2.2)
• Proper operatory environmental controls. (Sec. 2.4.1 thru
2.4.5)
• Protective eyewear for all persons in the operatory,
including the patient. (Sec. 5.2.3)
• Proper installation and set-up of the system. (Sec. 2.3, 2.4
and 4.5)
• Familiarity with system controls, including means to shut
down the system. (Sec. 3.2 thru 3.5)
• Appropriate indications and procedures for which this
system is designed and approved for. (Sec. 5.1)
• Regulatory requirements and conditions under which this
system may be used. (Sec. 5.1)
Please refer to the indicated Sections of this manual for each
of the listed topics to learn more about each subject. It is the
responsibility of the doctor and staff to be familiar with all of
these safety considerations prior to operating the laser.
3.2. Start-up and System Check
3.2.1. Handpiece Assembly
Before turning on your Precise SHP, make sure the handpiece
is assembled and ready for use. The disposable tip and
handpiece sleeve are parts of the device that are likely to

present, remove any liquid on the handpiece sleeve or tubing.
1. Remove the handpiece protective dust cap. (Figure 3.1)
2. Slide the handpiece sleeve over the fiber cable stem and
rotate it to securely thread the sleeve onto the fiber cable
stem. (Figure 3.2a)
3. Remove the protective cap from the shaft of the disposable
tip, and insert the tip shaft into the end of the handpiece.
You will know that the tip is securely seated when you feel
the tip snap into place and hear a slight click. (Figure 3.2b)
4. Slide the disposable barrier sleeve over the handpiece
assembly. If needed, puncture the barrier sleeve with the tip
so the tip fiber protrudes out of the barrier sleeve.
5. Your Precise SHP handpiece is ready to use
Assembly of the therapy handpiece is done by attaching the
therapy handpiece sleeve in the same manner as the surgical
sleeve as described in Step 3.2 above. No other attachments or
steps are needed for the therapy handpiece assembly.
Assembly of the whitening handpiece is accomplished by
attaching the reusable dispersion cone to the whitening sleeve
by aligning the locking pins in the cone with the groves in the

and video demonstrations.
Lock – This allows you lock the system
to prevent others from accessing the laser
controls or firing the laser. Entering your
password will unlock the unit.
On any of the screens after this point, you will see a menu
bar at the bottom of the screen. Each icon on the menu
bar represents one of the five selections just referenced.
Pressing the icon will take you to that screen, no matter
where else in the App you are at. The sixth icon is the
Main Menu.
3.2.6. Operate Screen
This screen shows the laser settings and enables the user to
adjust these settings to meet the needs of each procedure.
The top bar shows the working beam
Power settings. The value displayed is
in Watts. Press the increase button or
decrease button to select the Power
setting (output) desired, from 0.5 to
3.0 watts.
The second bar shows the Mode settings. Press the icon to
choose between Continuous Wave (CW)
or Pulse mode.
• Continuous Mode : : delivers a continuous flow of energy
(measured in Joules per second) equal to the value indicated
in the Power setting, i.e., set the laser for 2 Watts and while
activated the laser will deliver 2 Joules per second as long as
the foot pedal is depressed. Continuous Mode is generally
the fastest way to ablate tissues but heat can build up and
cause collateral damage to the target and adjacent tissues.
Cool the tissues being lased by using periodic blasts of air
from the air/water syringe and high speed suction. You may
use water to cool areas where there is prolonged exposure to
the laser’s beam. Avoid using the air syringe when you have
an opening in soft tissue adjacent to or within the surgery
site. An air embolism may occur as a result of air captured
within the tissue during the cooling process.
• Pulse Mode : delivers an on/off pulsing of the laser energy
to allow some cooling of the tissue in between emissions of
energy. In the Pulse Mode, the Precise SHP is programmed to
deliver 10 pulses of energy per second with each pulse
lasting for the amount of time (in milliseconds) shown on the
screen adjacent to the Pulse button. Press the Pulse button
repeatedly to cycle between 30, 50, and 75 milliseconds per
pulse.
• The pulse “duty cycle” of the unit is the percentage of the time
per second that the laser is emitting energy. For example,
if the duty cycle of the Precise SHP is set for 50, you will
have 1 energy pulse lasting 50 milliseconds with 1 period of
rest with no energy between each pulse lasting another 50
milliseconds. If the pulse were set at 75, then the laser would
activate for 75 milliseconds and rest for 25 milliseconds.
When the laser is emitting energy, it does so at the power
output selected on the Display. However, since it is not
emitting continuously, the net effect is a beam that behaves at
only a percentage of the power that a continuously running
beam would. Thus, if the system were set at 1.0 watts, a
pulse beam set at 30 would cut the same as if the laser were
continuously emitting at 0.3 watts. A pulse setting of 50 and
1.0 watts of output performs the same as a continuous beam
set at 0.5 watts, and so on.
• Aiming Beam: The next bar shows the aiming beam intensity
on a relative scale from 0 to 5, with 0 being “off” and 5
being the maximum output of the aiming beam. Press the
up or down buttons to select the Aiming Beam intensity. As
you change the setting, you will notice the aiming beam will
appear at the handpiece tip and blink for approximately 3
seconds so you can determine if the intensity is appropriate.
• Tip Selection: The bottom bar allows you to select which size
of tip is attached to the handpiece.
CAUTION - Make sure the size of tip is correctly
identified on this screen to ensure the Precise
delivers the correct amount of laser energy to the
tip.
CAUTION - Establish laser settings that are just
sufficient to perform the procedure. Excessive
power output and/or exposure time may create
collateral tissue damage. See Section 3.2.8.
Once all of the desired settings are established, press the Ready
button to place the laser system in Ready Status. Confirm that
the tip size is correctly selected. A check mark will appear on
the screen, blinking for 3 seconds, then remain steady on. The
Laser Ready Screen will appear.
3.2.7. Laser Ready Screen
This screen indicates that the laser
settings have been locked in and the
system initialized. With the check mark
steady on, the aiming beam activates
(unless the aiming beam intensity is
set at 0). When the system is in Ready
Status, a yellow indicator light will
appear on the front of the Base Module.
You are now ready to operate the
Precise SHP (see Section 3.3). When
you are through using the laser, press
the Standby key to return to the Operate Screen and place the
system out of Ready status.

3.3. Operating the Precise SHP
3.3.1. Optical Fiber Check
When the system is in Ready Status, the aiming beam should
be visible (unless set at 0). As the aiming beam passes down
the same optical fiber as the working beam, it provides a good
means of checking the integrity of the optical fiber. Aim the
handpiece at a piece of blank paper and inspect the aiming
beam spot. The spot should be round and the intensity should
be consistent throughout the spot. If the aiming beam is not
present at the tip of the handpiece, if its intensity is reduced or
if it looks diffused, this is a possible indication of a damaged or
malfunctioning optical fiber or handpiece cable. If the aiming
beam is at a setting other than 0 and no aiming beam is visible,
review the handpiece assembly procedure in Section 3.2.1
and make sure the handpiece and tip have been assembled
properly. If there is still no aiming beam, there may be a
problem with the handpiece cable or Base Module. Contact
the CAO Group Service Department for troubleshooting tips or
further instructions. See Section 6.2.
CAUTION – Do not activate the laser beam without
a tip attached to the handpiece.
3.3.2. Test Fire the Precise SHP
Always test-fire the Precise SHP prior
to use. Set Power to 1 Watt or less
and place in Continuous Wave mode.
Place into Ready Status. Step on the
foot pedal to activate the laser for
1 – 2 seconds while aiming the fiber
onto a 2 x 2 gauze sponge wetted
with water. (Do not use alcohol or any
other combustible material to wet the 2
x 2 sponge as it may ignite.) Confirm
that the Display shows the red Firing indicator screen (shown
at right) and that the Base Module emits a tone when firing.
Release the foot control switch and touch the Operate Icon to
place the system in Standby Status. Change the power output to
2.0 watts, and press the Ready Button. Aim the laser at a piece
of paper or gauze that has been marked with blue or black ink.
Step on the foot pedal to activate the laser for 1 – 2 seconds. A
small plume of smoke should emit from the target site, confirming
that the working beam is functioning properly. Release your foot
from the pedal and place the system in Standby Status.

3.3.3. Procedure Settings
In the Operate Screen, select the laser settings appropriate
for the procedure. Please refer to Section 3.2.8 for setting
values appropriate for a variety of common soft-tissue
procedures. Once all of the desired settings are established,
press the Ready button to place the laser system in Ready
Status.
3.3.4. Activate the Working Beam
Once the system is in Ready Status, you are ready to activate
the working beam. Ensure that all persons in the operatory
are wearing eye protection. Position the handpiece tip over
the intended site, and then step on the foot pedal to activate
the working beam. The Display will show a Laser Emissions
Occurring screen and the front of the Base will show a red
indicator light. The light will be continuously on when in
Continuous mode, and will rapidly blink when in Pulse
mode. The Base will also emit a repeating audible signal
to let you know the laser beam is active, without having to
look away from the treatment to confirm the laser status.
While the working beam is active, move the tip over the
desired site using even, painting type strokes, going back
and forth along the target tissue until the desired effect is
achieved. Avoid leaving the tip over one location for an
extended period as this may causing burning and charring
of the tissue. During an extensive procedure, the tip may
become fouled with debris and the laser emissions may
become blocked. If you notice this is occurring, discontinue
the working beam and place the unit in Standby Status.
Remove the existing tip and attach a new tip, then proceed
with the procedure.
For surgical procedures, pass the fiber along the treatment
site with a steady paintbrush type stroke. It may be necessary
to repeat the motion over the site to achieve the desired
depth and/or results. For temporary pain relief sweep the
handpiece over the treatment area in a steady circular
motion for 5 minutes. Effective results are often achieved
through brief, but repeat office visits over several days.
For whitening, position the handpiece over the teeth and
expose for 5 minutes. Continuously monitor the status of the
whitening formula to ensure the teeth remained covered by
the formula. Apply suction as needed to pick up whitener
that may separate from the teeth.
CAUTION: Visible and invisible laser radiation
will be emitted from the handpiece tip. Make
sure these instructions are followed exactly and
all precautions and preparations are in place to
avoid unintended exposure to laser radiation.
CAUTION: For tooth whitening procedures,
do not expose the whitening gel for more than
5 minutes. Excessive tooth temperatures may
occur.
CAUTION: Use of controls or adjustments or
performance of procedures other than those
specified herein may result in hazardous
radiation exposure.
CAUTION: Applying excessive force to the
fiber tip while the laser energy is emitting could
create a situation of fiber fragments. When
contacting tissue or other material, the debris
adheres to the fiber and absorbs the laser
energy, generating an intense amount of heat.
This heat could cause the glass fiber to crack or
fragment. Always remove any fragments from
the fiber and/or work area.
3.4. Daily Shutdown
Once you have concluded the procedure, ensure that the
system is in Standby Status. On the Display Module, press
the Lock key. Alternatively, press the ‘Home’ button of the
iPod touch to close the Precise SHP App. Press and hold
the power button on the Base Module for 3 seconds to turn
the Base Module off. Detach the tip and dispose of it in the
appropriate contaminated sharps container. Remove the
handpiece sleeve from the fiber cable, attach the handpiece
tip cap and clean the sleeve and cable as indicated in
Section 4.1. The handpiece is magnetic, and magnets
within the top of the Base Module and in the Display Stand
help to hold the handpiece in place when it is stored in
these locations.
CAUTION: Tips are single-use only and are to
be disposed of after each patient.
CAUTION: Failure to use the tip cap could
permit dust and debris to collect on the optical
interface and permanently damage the
handpiece optics.
3.5. Emergency Shutdown
If for any reason there is a need to terminate laser
emissions quickly, numerous means are provided to do so:
• Release the foot pedal – releasing the foot pedal will
deactivate the working beam. NOTE: The aiming beam
will still be active.
• Laser Stop Button – Both the display and base module
feature a laser stop button. These switches are redundant
to each other. Pressing the Laser Stop on either the

18
display or base module will deactivate the working and
aiming beams. The display screen will return to the Operate
Menu and be in the Standby Status.
• Close the App – Pressing the ’Home’ button of the iPod touch
at lower center will close the Precise SHP App and deactivate
all laser emissions.
• Power Button – Pressing the Sleep button on the Display, or
the Power button on the Base will deactivate laser emissions.
• Power Source – Removing the power cord from the back of
the Base Module, or detaching the battery pack from the
Base, will deprive the laser of power and terminate all laser
emissions.
3.6. Laser-assisted Tooth Whitening
After following the handpiece setup instructions provided
in Section 3.2.1, appropriate cheek retraction and tissue
protection measures should be applied to prevent the whitening
gel from contacting soft tissue surfaces. Apply the whitening
composition according to the manufacturer’s instructions for
the composition. Ensure the appropriate settings are applied
to the Precise SHP as indicated in Section 3.2.8 for the “Tooth
Whitening” application, or select “Tooth Whitening” from the
presets menu.
Position the handpiece so the edge of the dispersion cone
is approximately 1-3mm from the surface of the whitening
composition. Avoid having the cone directly contact the
whitening composition. The whitener could collect on the inside
surface of the cone and affect the uniform emission pattern of
the laser energy, creating “cold spots” where the whitener on
the teeth doesn’t receive as much laser energy as it should.
The dispersion cone is sized such that is covers approximately
one quadrant of the patient’s mouth. Operate the laser for
approximately 1 minute, then position the dispersion cone
over the next quadrant and expose this quadrant for 1 minute.
Continue until all four quadrants have been exposed for
approximately 4-5 minutes cumulatively.
4. Set-Up, Care, and Maintenance
4.1. Infection Control
Prior to applying the infection control measures mentioned below
for the respective portions of the device, all portions of the device
should be visually inspected for soiled surfaces or contaminants
prior to use. Wear protective gloves prior to cleaning. Wipe
the surface with a clean cloth or gauze moistened with a 70%
isopropyl alcohol solution. Allow the surface to dry for at least
15 minutes before proceeding with the specific infection control
directions listed below.
4.1.1. Display and Base Modules
We recommend using barriers as a primary infection control
protocol. Place a barrier material over the Display Module
touch screen prior to treating each patient. The Display has
been demonstrated to function properly with commonly used
barrier materials.
The exterior of the Display and Base modules may also be
cleaned using a liquid disinfectant similar to BIREX™, Chlorox®,
or CaviWipes®. Do not spray the disinfectant directly on the
chassis. Apply the disinfectant to a gauze sponge or cloth, then
wipe the external surfaces. Ensure that the surface appears
thoroughly wet. Allow the surface to remain wet for at least 5
minutes (10 minutes for BIREX). You may need to reapply the
disinfectant in order to achieve this. After 5 minutes of contact
time, dry with the surface with a new, dry cloth, or allow the
item to air-dry. Do not use cleaning pastes or slurries that
contain abrasive particulates to clean the system.
4.1.2. Handpiece Stem, Cable and Tip Cap
The fiber cable handpiece stem cannot be detached from the
optical cable, nor can the optical cable be detached from
the Base Module. After each procedure, the stem and tubing
exteriors should be wiped cleaned using a liquid disinfectant
similar to BIREX, Chlorox, or CaviWipes applied with a clean
cloth or gauze. Do not spray the disinfectant directly on the
chassis. Apply the disinfectant to a gauze sponge or cloth, then
wipe the external surfaces. Ensure that the surface appears
thoroughly wet. Allow the surface to remain wet for at least 5
minutes (10 minutes for BIREX). You may need to reapply the
disinfectant in order to achieve this. After 5 minutes of contact
time, dry with the surface with a new, dry cloth, or allow the
item to air-dry.
Do not touch or apply any disinfectant to the terminal end of
the fiber cable stem. Do not immerse the fiber cable stem in the
disinfectant solution as this may deposit residual compounds
on the optical interface in the fiber stem can thus optically
contaminate the interface. Do not use cleaning pastes or slurries
that contain abrasive particulates to clean the system. The
handpiece tip cap should always be attached to the stem when
a tip is not attached. The cap should be cleaned in the same
way as the handpiece cable.
CAUTION: Avoid any liquids or particulate
materials coming in contact with the distal end
of the fiber cable stem. Doing so may deposit
Fiber Cable handpiece

19
care | maintenance
residual foreign substances on the optical fiber
termination and will cause premature burning
of the optical fiber.
CAUTION: Avoid bending the handpiece
tubing at sharp angles. Doing so may damage
the optical fiber inside and could result in
harmful or unintended laser emissions.
4.1.3. Handpiece Sleeves
The handpiece sleeves are supplied in a non-sterile
condition and should be sterilized prior to first use and
prior to each patient. It is recommended that the pain relief
handpiece sleeve be disassembled prior to sterilization.
All components of the therapy handpiece sleeve, including
the glass window, can be autoclaved. Sterilization of the
handpiece sleeve by autoclave has been validated using
a gravity cycle method. Set the autoclave parameters for
250°F (121°C), at least 18 psi (124 kPa), and run for 30
minutes, followed by a 30 minute drying phase. Make sure
the sleeve is dry before it is re-attached to the fiber cable
stem. Once sterilized, ensure that the sleeves are handled
and used in a sterile environment.
4.1.4. Disposable Fiber Tips
The handpiece tips are single-use only and are to be
disposed of after each patient. Inspect the package to
ensure there are no tears or punctures. DO NOT USE if
such flaws are visible. When the pouch is opened, care
should be taken to minimze the accumulation of foreign
debris or contaminants on the tips prior to use. Use a clean
cloth moistened with a water or alcohol-based disinfectant
to gently wipe the tip fiber and housing. DO NOT remove
the clear cap and wipe the tip stem.
DO NOT attempt to autoclave the tips. They are not designed
to withstand such a process and may melt or distort. Do not
immerse the tips in any liquid as liquid residues may collect
on the optical fiber and absorb laser energy, reducing the
effectiveness of the laser and possibly contaminating the
fiber cable optics.
During use, the fiber on the end of the tip may become
fouled with tissue or debris. When this occurs, laser energy
is absorbed at the end of the tip rather than transmitted to
the target tissue. This is often manifested by an intense white
flash at the end of the fiber as organic matter is vaporized.
If you find that the laser is losing cutting efficiency as you
continue with the procedure, stop the laser emission and
place the system into Standby Status. Use a clean lint-free
cloth to remove foreign material adhered to the tip. DO NOT
use a cloth premoistened in alcohol as this flammable liquid
may still coat the fiber tip when the laser is reactivated. If
wiping the tip does not improve laser performance, it may
be necessary to discard the existing tip and attach a new
tip.
DO NOT use the tip if the packaging is found to be torn,
punctured, opened, or otherwise compromised.
DO NOT reuse the tip. The handpiece tip is for one-time
use only.
4.1.5. Whitening Cones
The whitening cones are supplied in a non-sterile condition.
Prior to first use and after each patient, the cone should be
cleaned according to the instructions provided in Section
4.1. Following cleaning, the cone should be sterilized.
Sterilization of the whitening cone by autoclave should
be done using a gravity cycle method. Set the autoclave
parameters for 250°F (121°C), at least 18 psi (124 kPa),
and run for 30 minutes, followed by a 30 minute drying
phase. Make sure the cone is dry before it is re-attached
to the whitening handpiece sleeve and subsequently to the
fiber cable stem. Once sterilized, ensure that the sleeves are
handled and used in a sterile environment.
If whitening compound inadvertently comes into contact
with the cone, use a clean gauze to wipe away the whitener.
4.1.6. Single-use Barrier Sleeves
Single-use barrier sleeves or membranes should be applied
to the device to reduce soiling of the device– particularly for
portions of the device that will be contacted by the clinician

over the course of the procedure. CAO Group makes available
barrier sleeves for the Display Module and the Handpiece
assembly. See Section 9 for ordering information.
4.2. Foot Pedal Battery Replacement
Follow these procedures to replace the foot pedal battery.
1. Make sure the Base Module is completely turned off before
replacing the battery in the foot pedal.
2. Place the pedal face-down on a hard, clean surface.
3. Use a Phillips head screwdriver to remove the four screws
securing the base plate to the foot pedal housing.
4. Remove the base plate.
5. Remove the battery from the compartment and detach the
battery terminal.
6. Remove the new battery from its package and attach the
battery to the terminal.
7. Insert the new battery into the compartment. Make sure the
connector is on the same side of the compartment as the
lead wires that attach to the terminal. Make sure all lead
wires are placed back inside the compartment.
8. Replace the base plate and screw in the four screws until
moderately tight. DO NOT over-tighten the screws.
9. Place the pedal face up. Allow 1 minute after completing
this process to check the pedal functionality as described in
Section 2.10.
NOTE: An extra 9-volt battery should be kept on
hand in case the battery needs to be replaced
during usage.
NOTE: The battery supplied with the Precise SHP
system is a non-rechargeable lithium battery that
provides for approximately 100 hours of usage. It
is recommended that the replacement battery also
be a lithium battery. The more common alkaline
type battery may be used, but be advised that these
batteries only provide approximately 35 hours of
use.
NOTE: During operation, the status of the battery in
the foot pedal can be monitored. See Section 3.2.8.
4.3. Maintenance and Servicing
This manual describes the steps necessary to operate and
maintain the Precise SHP in a proper working condition. If
difficulties are encountered, please refer to the applicable
sections of this manual. If the care and cleaning of the device
is followed as described, the Precise SHP will provide years of
consistent performance. No other maintenance activities should
be needed or undertaken. No portions of the Precise SHP
are serviceable by the operator. If any errors or malfunctions
are encountered, please contact the CAO Group Service
Department (877.236.4408) as described in Section 6.2.
CAUTION: Do not open or attempt to service the
Base Module. Exposure to visible and invisible
laser radiation may occur.
WARNING: No modification of this equipment
is allowed. Attempting to alter, or to perform
maintenance not specified in this manual could
create risks of electric shock, hazardous laser
radiation exposure, and will void the warranty.
4.4. Calibration
The Precise SHP Laser uses solid-state circuitry to continuously
monitor the power output and adjusts the power supplied to the
laser module to keep the output consistent with the user defined
setting. If output levels are more than ± 20% of the set value,
the unit is designed to shut down power to the laser, and an
audible alarm will sound. If this happens, the unit should be
turned off and allowed to sit for 5 minutes and turned on again.
If the laser then performs without beeping, the microprocessor
has been able to make operational adjustments and the unit will
perform its functions. If, upon restart, the unit continues to beep,
the unit will need to be sent in for adjustment by CAO Group,
Inc., Service Department.
We suggest that your practice establish an internal calibration
program for your laser. Recalibration is recommended at
a minimum of once per year based on average usage.
Recalibration may be performed by the manufacturer by
returning the unit. Alternatively, you may purchase a calibrated
hand–held power meter approved for use with 810nm devices
to check power output. Output should be checked at the 1, 2,
