Toa VM-3240VA - Equipment Operation Upon Failure Detection and Recovery Procedure

9.4. Equipment Operation upon Failure Detection and Recovery Procedure
If any malfunction is detected within the system, the buzzer sounds, the failure indicator flashes and failure
information* is displayed on the VM-3240VA’s LCD screen. The operations of other system equipment differ
when a communications error or other failures occur. The following are rough guidelines on actions to take
after such failures have been detected.
The procedure for recovery from irregularities other than communications failures is:
1. Perform failure acknowledgment.
2. Remedy the cause.
3. Perform failure reset.
Recovering from communications failures:
When a failure is detected in communications between an individual component and the VM-3240VA,
component operation can no longer be performed. First, remedy the cause of the failure.
If communication returns to normal, the original condition will automatically be restored.
* For LCD failure display, refer to page 41.
