7 DIAGNOSTICS AND

TROUBLESHOOTING

INTRODUCTION

This section explains:

• General troubleshooting using built in diagnostic tools

• BIS VISTA Monitoring System troubleshooting procedure.

• 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.
