7-4 SurgiStat II Service Manual
Understanding Error Codes and Audio Tones
The SurgiStat II Generator includes automatic, continual self-diagnostics. If the
diagnostics detect an error, the system displays an error code, sounds an audible
tone, and deactivates the output power.
Any errors detected will shut down the RF output power.
Most error codes result from faults in accessories attached to the unit. The
following table lists the error codes, describes the error, and recommends actions
to take to resolve the error.
Notice
Internal firmware self-diagnostics continually monitor unit operation to ensure
proper and safe performance.
