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.
