INTRODUCTION
t is recommended that personnel study this
manual before attempting to operate, clean,
and/or sterilize the Linvatec 3CCD Digital
Camera System (IM3300, IM3301) and acces-
sories. The safe and effective use of this equip-
ment requires the understanding of and
compliance with all warnings, cautionary
notices, and instructions marked on the product,
and included in this manual.
1.1 Intended Use
The Linvatec 3CCD Digital Camera System is
intended to provide video capabilities in a vari-
ety of endoscopic surgical procedures, including
but not limited to, orthopedic, laparoscopic, uro-
logic, sinuscopic, plastic and as an accessory for
microscopic surgery.
1.2 GeneralWarnings and Cautions
1. This equipment is designed for use by med-
ical professionals completely familiar with
the required techniques and instructions for
use of the equipment. Read and follow all
warning and cautionary notices and
instructions marked on the product and
included in this manual .
2. Do not attempt to open or service
controller chassis while under
warranty, as this may void your
warranty. There are no user-serviceable
parts inside. Removing the cover may intro-
duce an electric shock hazard by exposing
you to dangerous high voltages or other
risks. If the system malfunctions, return it
for service immediately.
3. Do not use camera with incompatible
equipment or accessories that are not autho-
rized by Linvatec. Doing so may void certi-
fications and/or warranties.
4. Prior to each use, the controller and all
associated equipment must be inspected for
proper operation. Visually inspect lenses to
assure there are no scratches, chips or
cracks.
5. Do not expose controller to moisture, oper-
ate in wet areas, or place liquids on or
above controller.
6. Do not excessively bend or kink the instru-
ment power cord.
7. The scope tip can get extremely hot as a
result of high intensity light and can
cause severe burns.
8. Handle all equipment carefully. If controller
or camera head is dropped or damaged in
any way, return it immediately for service.
9. If the camera head is damaged in any way,
or cable or connector jacket are cut, do not
autoclave camera head, or immerse camera
head in liquid (water, chemical disinfectants
or sterilants, etc.). Notify your Linvatec
Sales Representative.
10. Store camera head and all accessories in a
protective container to prevent damage dur-
ing storage. Do not store controller where it
will be exposed to temperatures in excess of
122 ° F (+ 50°C).
11. Do not use in presence of flammable anes-
thetics, gases, disinfecting agents, cleaning
solutions, or any material susceptible to
ignition due to electrical sparking.

12. After each use, thoroughly clean unit and
accessories (See “3.1 Cleaning and Steril-
izing” on page 22 ).
13. Disconnect product prior to applying car-
diac defibrillation to patient.
14. Equipment grounding is vital for safe oper-
ation. Plug power cord into a properly
earthed mains supply outlet whose voltage
and frequency characteristics are compati-
ble with those listed on unit or in this man-
ual. Do not use plug adapters or extension
cords; such devices defeat the safety ground
and could cause injury.
15. External equipment, that will be connected
to signal input and signal output ports or
other connectors, shall comply with rele-
vant IEC standard (i.e., IEC 950 for IT
equipment and IEC 601 series for medical
electrical equipment). In addition, all such
combinations - systems - shall comply with
the standard IEC 601-1-1 (Safety require-
ments for medical electrical systems).
Any person who connects external
equipment to signal input and signal output
ports or other connectors has formed a
system and is therefore responsible for the
system to comply with the requirements of
IEC 601-1-1. If in doubt, contact a qualified
technician or your local representative.
16. This equipment has been tested and found
to comply with the limits for medical
devices to the IEC 60601-1-2 and
EN60601-1-2. These limits are designed to
provide reasonable protection against harm-
ful interference in a typical medical instal-
lation. This equipment generates, uses and
can radiate radio frequency energy and, if
not installed and used in accordance with
the instructions, may cause harmful inter-
ference to other device(s) in the vicinity.
However, there is no guarantee that interfer-
ence will not occur in a particular installa-
tion. If this equipment does cause harmful
interference to other devices, which can be
determined by turning the equipment off
and on, the user is encouraged to try to cor-
rect the interference by one or more of the
following measures:
(a) Reorient or relocate the receiving
device.
(b) Increase the separation between the
equipment.
(c) Connect the equipment into an outlet
on a circuit different from that to which
the other devices are connected.
(d) Consult the manufacturer or field
service technician for help.
This unit was not evaluated for use with
electrosurgical devices which access the
site via the same endoscope as the light
source and camera. The unit must be re-
evaluated prior to use with electrosurgical
devices when they will operate through the
same endoscope as the light source and
camera.

SYSTEM INSTALLATION
and OPERATION
2.1 Installation
NOTE: For various system configurations,
reference Figures 2-1 through 2-6 on the
following pages. Figures shown indicate
connections for S-Video and RGB setups.
The same connections may be used for
non-S video setups as depicted by the S-Video
configurations, but use BNC cables and route
to appropriateVIDEO connectors.
1. Attach the AC power cord to the controller
receptacle and a standard grounded wall
outlet.
2. Connect the appropriate video cables
(S-Video, BNC or RGB) to the correspond-
ing output connectors on the rear of the
controller.
3. Connect the other end of the video cables to
the corresponding connectors (S-Video to
S-Video, BNC to BNC or RGB to RGB) on
the monitor and/or any other peripheral
equipment.
4. Utilizing the remote cable allows activation
of either a recorder or printer from the cam-
era head buttons. Connect the remote cable
(supplied) to the appropriate remote outlet
on the rear of the camera controller, then to
the appropriate remote outlet on the
recorder and printer.

2.1.1 Displaying Color Bars
Color bars test pattern allows the user to match
the color between the camera controller and the
monitor. To activate the color bar test pattern, do
one of the following:
1 - Turn the controller power on without a
camera head installed, OR,
2 - If a camera head is connected and the power
is on, unplug the camera head.
2.1.2 White Balance Operation
Various video system components can affect the
color temperature of light transmitted to the sur-
gical site. It is important to assemble the entire
video endoscopic system; camera head (and
coupler if applicable) endoscope, light source
and light guide before white balancing the con-
troller. If any equipment in the video endoscopic
system changes, repeat white balancing.
1. To white balance the camera controller:
(a) Set the light source brightness to the
preferred setting.
(b) Using a stack of 4x4 white gauze, hold
the tip of the scope approximately one
inch away from the gauze.
(c) Using the camera brightness control
buttons, adjust the light intensity to a
uniform level over the entire image on
the monitor (no glaring) so the picture
is of nominal brightness to the user.
(d) Hold the scope tip steady and press the
controller “White Balance” button or
the camera head button (camera head
button will only activate white balance
if a “Push Camera Head Button”
message appears on the monitor
screen). During white balance a “White
Balancing” message displays.
When white balance is completed
successfully a “White Balance
Complete” message displays.
If white balance is not completed
successfully a “White Balance Not
Completed” message displays. Check
your setup and try again.
NOTE: White balance default at start-up is
the last used setting.

the auto shutter on or off.
(a) The automatic shutter control elimi-
nates the need to manually adjust the
light source brightness since brightness
is controlled through the camera con-
troller. With auto shutter on, the con-
troller’s circuitry is set to automatic-
gain shutter operation. The camera
controller now controls the brightness
and automatically compensates for
varying lighting environments to obtain
the highest quality image possible.
With the auto shutter off, the control-
ler’s circuitry is set to a fixed 1/60 sec-
ond exposure. The light source must be
manually adjusted to vary the amount
of light if the auto shutter is off.
