User Troubleshooting
The CUSA EXcel system runs nearly trouble free. However, on occasion, a
problem may arise. This section describes some conditions that may occur before
or during the normal course of surgery. They are easy to diagnose and to fix.
Warning
Electric Shock Hazard Do not touch any exposed wiring or conductive surface while
the system is disassembled and energized. Never wear a grounding strap when working
on an energized system.
Electric Shock Hazard Take appropriate precautions (such as the use of isolated tools
and equipment; use of the “one hand rule,” etc.) when taking measurements or
troubleshooting the system.
Notice
Electrostatic Sensitive Devices This unit contains electrostatic sensitive components.
When repairing the system, work at a static control workstation. Wear a grounding strap
when handling electrostatic sensitive components. Handle circuit boards by their
nonconductive edges. Use an antistatic container for transport of electrostatic sensitive
components and circuit boards.
Warning
Do not activate vibration or the CEM handswitching nosecone while using the tip cleaner.
Tip damage, user injury, electrical shock, or any combination of these effects may occur.
