Product Description and Intended Use
The Stryker X8000 Light Source is a light-generating unit designed to illuminate
surgical sites during endoscopic applications. The X8000 uses a 300-watt xenon
bulb to generate bright, crisp light, which it delivers to the surgical site via a
fiberoptic light cable. The X8000 is compatible with all Stryker light cables, and,
with the proper light cable and adapters, can connect to any flexible or rigid
endoscope.
The X8000 is equipped with Electronic Scope Sensing Technology (ESST), a
special safety feature that helps prevent accidental burns caused by a light cable
that is not connected to the scope. For more information, refer to the section
“Checking the ESST Feature”. When operated with an ESST light cable, the X8000
senses when the scope and the light cable are separated and places the light source
in Standby mode. In Standby mode, the X8000 will reduce light output to a
minimum, preventing the light cable from generating excessive heat.

Checking the ESST Feature
The X8000 is equipped with Electronic Scope Sensing Technology (ESST), a
special safety feature that helps prevent accidental fires or burns to the patient or
user caused by a light cable not connected to a scope. This feature will only work
if the X8000 is used with an ESST light cable. When operated with an ESST light
cable, the X8000 senses when the scope and light cable are separated, and places
the light source in Standby mode. In Standby mode, the X8000 will reduce light
output to a minimum, preventing the light cable from generating excessive heat.
To verify the ESST feature is active, perform the following test before every
surgical procedure:
1. Set up the X8000 system with an ESST light cable and scope, and then
power on the system.
2. Place the X8000 in Run mode.
3. Remove the light cable from the ESST scope adapter.
The X8000 should return to Standby mode, indicating that the ESST feature is
functioning properly.
WARNING ALWAYS CHECK TO ENSURE THAT THE UNIT HAS SWITCHED INTO
STANDBY MODE, BEFORE ASSUMING ESST SAFETY PROTECTION. IF
THE UNIT FAILS TO RETURN TO STANDBY MODE, THERE MAY BE A
FAULT WITH THE ESST FEATURE. INTHIS CASE, DO NOT ASSUME
ESST SAFETY PROTECTION, AND RETURN THE UNIT FOR SERVICE.
WARNING EVEN WITH ESST PROTECTION, OR WHEN THE X8000 IS IN
STANDBY MODE, NEVER PLACE THE TIP OF THE LIGHT CABLE OR
LIGHT CABLE ADAPTER DIRECTLY ON THE PATIENT, DRAPES OR
OTHER FLAMMABLE MATERIAL, AS BURNS OR FIRE MAY RESULT.
THE SCOPE TIP, SCOPE LIGHT POST, LIGHT CABLE ADAPTER, AND
LIGHT CABLE TIP WILL TAKE SEVERAL MINUTES TO COOL OFF
AFTER BEING PLACED IN STANDBY MODE, AND THEREFORE MAY
STILL RESULT IN FIRE AND/OR BURNS TO THE PATIENT, USER, OR
AN INANIMATE OBJECT IF NOT USED PROPERLY. DONOT PLACE
THE SCOPE OR THE LIGHT CABLE ON THE PATIENT, ON THE
DRAPES, OR OTHER FLAMMABLE MATERIAL, EVEN WHEN THE
DEVICE IS IN STANDBY MODE.

instructions.
Caution Do not use any abrasive cleaners. Do not allow any liquid to
drip into the unit.
Caution Do not sterilize or immerse the X8000.
Caring for the Bulb Module
The X8000 uses a Xenon bulb, which has a guaranteed life of 500 hours when
used properly. Always follow these guidelines to ensure maximum bulb life:
1. Clean the bulb face with alcohol and a cotton swab if it is touched. Dirt
or oil on the bulb face will cause the bulb to heat unevenly and fail.
2. Do not power on and off the bulb in rapid succession. Allow the bulb to
run for at least five minutes once it has been powered on. Failure to do so
can cause the bulb to rapidly darken and fail.
3. The X8000 has been designed to start the bulb under most conditions,
even when it is hot. However, if the bulb does not start within 10 seconds
after the X8000 has powered on, turn the unit off and wait at least five
minutes for the bulb to cool before restarting. Further attempts to start
the bulb can damage the bulb and possibly the internal circuitry.
Replacing the Bulb Module
Replace the bulb module when the LCD indicates 500 hours or when the bulb no
longer sufficiently illuminates the surgical site. If possible, replace the bulb
module between surgical procedures.
WARNING DURING OPERATION, THE BULB AND THE HOUSING AROUND THE
BULB MAY BE HOT. WAIT AT LEAST THREE MINUTES FOR THE
BULB TO COOL BEFORE HANDLING IT.
