Status messages, causes, and corrective actions
7.1 General Troubleshooting
The BIS VISTA Monitoring System has both automatic and manual diagnostic features.
These features check the BIS VISTA Monitoring System’s operability and status, and report
software and hardware malfunctions.
IF ANY FAILURES ARE NOTED, SEE SECTION 7.3 “BIS
VISTA System Messages and Corrective Actions”
The
power-up diagnostics run automatically the first time the unit is powered on, after the
battery or power supply have been replaced, or after the Reset button has been pressed.
Software image checksums and trend data memory are tested and repaired if necessary.
The
automatic diagnostics run continuously in the background while the unit operates.
These procedures check the BISx for the following conditions: interface faults, disconnect,
lead off, and power faults.
The
manual diagnostics are operator initiated using the monitor touch keys and menu
choices. These procedures check the digital signal converter function within the BISx.
NOTE:
The manual diagnostics can be run safely while the patient is connected to
the BIS VISTA Monitoring System; however, running the diagnostics will
temporarily disrupt monitoring. Do not run the DSC Self Test during
electro-cautery as it may erroneously indicate a failure of the BISx.
