CHECK
1. Self-test
A. Periodicity
It is recommended by the manufacturer to test the ELT to detect any possible
failure.
It is recommended to perform a self-test once a month by pilot or maintenance
personnel from the cockpit (Remote Control Panel) but it should not be done
more than once a week.
However, each self-test consumes energy from the battery. Should self-tests
be carried out more often than the maximum allowed, the battery life-time might
be shorter than specified.
B. Self-test procedure
• Check that the antenna is correctly connected.
• Switch from position "OFF" to position "ARM" or press "RESET & TEST"
on the Remote Control Panel (ensure that the ELT switch is in the "ARM"
position).
- The buzzer operates during the whole Self-test procedure.
- After a few seconds, the test result is displayed with the visual indicator
as follows:
• One long flash indicates that the system is operational and that no
error conditions were found.
• A series of short flashes
(see Remark below)
indicates the test has failed.
Remark: The number of flashes gives an indication of the faulty
parameter detected during the self-test.
Do not perform Self-test without the antenna connected.
If self-test fails, contact the distributor as soon as possible.
Unless a waver is granted, flight should be cancelled.
