Faults
8.1.2 Faults occurring during operation
During operation, other faults which can be attributed to other influencing factors
may occur. Notification of faults detected by the ultrasonic generator is provided in
two ways:
An alarm tone sounds.
The
ERROR
indicator light goes on.
When the ultrasonic generator has notified you of a fault, the cause of the fault must
be eliminated.
However, the ultrasonic generator does not detect all faults. For this reason, note any
faults occurring during operation. If you discover a fault, the cause of the fault must
be eliminated. Continuing to treat a patient despite the presence of a fault may result
in life-threatening injury to the patient. If a fault directly endangers the patient, turn
off the ultrasonic generator immediately.
