1.0 Introduction
1.1 SCOPE
This manual is intended to be used as a reference guide for
electronics technicians and the Stryker Repair Team in the
analysis and repair procedures for the X-7000 Light
Source. It is meant to be used in conjuction with the
Stryker X-7000 Universal Light Source Operating and
Maintenance Manual (Stryker P/N 1000-400-651) and
does not replace existing documentation.
Stryker Endoscopy maintains a complete repair depart-
ment for the sole purpose of providing efficient and reli-
able service.
1.2 RESPONSIBILITY
Stryker Endoscopy accepts full responsibility for the effects
on safety, reliability, and performance of the equipment

1.3 UPGRADES
The Stryker Endoscopy X-7000 Light Source is a high per-
formance device designed for use with Stryker Endoscopy
medical video cameras to provide outstanding illumina-
tion of the surgical site across all endoscopic applications.
With the proper light cable and adapters, it can be con-
nected to any flexible or rigid endoscope. Stryker Endos-
copy reserves the right to incorporate improvements
without notice. However, updated parts will be fully inter-
changeable with older versions and will offer at least the
same level of quality and performance.
Stryker Endoscopy will inform customers of significant
upgrades to the product. Contact your Stryker representa-
tive for up-to-date information on available options and
upgrades to equipment as well as updates to this manual.

2.1 GENERAL RECOMMENDATIONS
The Stryker Endoscopy Model X-7000 Light Source is a
precision instrument which has been engineered and man-
ufactured with great care to ensure the safety of operators
and patients. In order to maintain the high level of safety
and reliability required of the X-7000, it is important to
fully understand and comply with all required procedures
set out herein.
If some part of a procedure is omitted or adequate equip-
ment is not used, the safety and performance of the device
may be unknowingly compromised. It is strongly recom-
mended that if any element in these procedures is beyond
the scope of the technician’s training, refer to section 1.7
for information on obtaining fully qualified professional
service at Stryker Endoscopy.
WA R N I N G : As is the case with all AC powered devices,
dangerous voltages are present. If adequate
safety precautions are not taken, results may
include damage to the equipment, injury, or
death. It is imperative that these procedures
be approached only by trained technicians
with proper equipment after fully reading
and understanding the steps involved.
2.2 POWER REQUIREMENTS
• There is one AC power cord for the X-7000 Light Source.
A separate AC power cord is normally required for any
other instrument being used.
• Each instrument is clearly marked for power require-
ments at the AC power cord connection.
• Testing the outlet for proper grounding and polarity is
highly recommended prior to connecting the X-7000
Light Source. If available, a ground-fault-interrupt type
outlet will provide an additional level of safety.
NOTE: A proper electrical installation procedure will
ensure that all associated signal cabling is cor-
rectly installed prior to applying AC power to the
system.
2.3 AMBIENT REQUIREMENTS
Ensure that:
• The distance between the X-7000 Light Source and the
associated devices does not exceed the available cable
length.
• Controls will be easily accessible to operator.
• Ventilation is not obstructed around the unit. Avoid
locations with excessive heat or temperature fluctua-
tions, such as direct sunlight.
2.4 CONNECTIONS AND WIRING
Please refer to the procedures detailed in the X-7000 Uni-
versal Light Source Operating and Maintenance Manual
(Stryker P/N #1000-400-651).
2.5 VERIFY OPERATION
After ensuring that both power and signal connections
have been correctly made, place the power switch in each
unit to the “ON” position. Check that an image is present
on the monitor.
