Valleylab CUSA EXcel-8 - Replacement Procedures

Warnings, Cautions, and Notices
Troubleshooting
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.
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.
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.
Replacement Procedures
Electric Shock Hazard Only trained biomedical engineers and technicians are
authorized to service the CUSA EXcel system.
Electric Shock Hazard Do not touch any exposed wiring or conductive surface
while the CUSA EXcel system is disassembled and energized. Never wear a
grounding strap when working on an energized CUSA 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 CUSA EXcel system.
High Current Hazard Do not touch the ultrasonics PCB heat sink while the
CUSA EXcel system is energized. The heat sink is isolated from ground, and can
deliver very high current, resulting in injury.
