TESTING
This section describes the AED automatic self tests and the test load test. If testing indicates a problem,
refer to Troubleshooting on page 6-2. If you cannot correct the problem, remove the AED from active
service and contact authorized service personnel.
The AED stores the results of autotests and the external test load test in a Test Log. For information
about retrieving Test Log data, refer to page 4-4.
Service Indicator and Message
The service indicator appears if the automatic self-test detects a problem that requires service.
If the service indicator appears on the key panel (but not flashing), you can still use the AED if it is
needed for patient therapy. However, you should contact authorized service personnel to correct the
problem as soon as possible. The service indicator will display until the problem is corrected.
If the automatic self-test detects a problem that requires immediate service (such as a malfunctioning
charging circuit), the service indicator appears on the Readiness Display, the service indicator on the
key panel flashes, and the
CALL SERVICE message appears.
Turn the AED off and on. If the
CALL SERVICE message disappears, you can still use the AED if it is
needed for patient therapy. However, you should contact authorized service personnel to correct the
problem as soon as possible. If the
CALL SERVICE message reappears, the service indicator on the
device key panel will continue to flash and the message will remain on. Contact authorized service
personnel immediately to correct the problem. You should not use the AED until the problem is
corrected.
Power-On Self-Test
Whenever the AED is turned off for at least 60 seconds and then turned on, the AED performs a “cold
start.” During a cold start, the AED performs internal self-tests to check that internal electrical
components and circuits work properly. During the self-test, the AED displays the following messages:
If the AED requires service, the service indicator appears. Contact authorized service personnel to
