Warning
Be sure to disconnect the Voluson E-Series ultrasound system power plug and switch off the main
circuit breaker before you remove any parts. Be cautious whenever power is still on and covers are
removed.
Caution
Do not pull out or insert circuit boards while power is ON.
Caution
The system requires all covers. Do not operate the Voluson E-Series system unless all board
covers and frame panels are securely in place. The covers are required for safe operation, good
system performance and cooling purposes. When covers are removed, EMI may be present.
Caution
To ensure the mutual protection and safety of GE service personnel and our customers, all
equipment and work areas must be clean and free of any hazardous contaminants before a service
engineer starts a repair. This includes, but is not limited to, decontamination and/or sterilization,
depending on the application or use of the medical device.
