MAINTENANCE MANUAL
TESTING EMERGENCY LOCATOR TRANSMITTER.
The transmitter operates on the emergency frequencies of 121.5 and 243 M Hz; both of these frequencies
are monitored by the various FAA installations. Before performing any operational test of the ELT. the
following precautions should be observed:
- CAUTION -
Testing of an EL T should be conducted in a screen room or metal
enclosure to ensure that electromagnetic energy is not radiated
during testing. If a shielded enclosure is not available, testing may be
performed in accordance with the following procedures:
1. Test should be no longer than three audio sweeps.
2. If the antenna is removed, a dummy load should be substituted
during the test.
3. Test should be conducted only within the time period made up
of the first five minutes after any hour.
4. If the operational tests must be made at a time not included
within the first five minutes after the hour, the test should be
conducted with the closest FAA Tower or Flight Service
Station.
Consult FA A A dvisory Circular A C 20-81 for detailed information
concerning the above caution.
1. Remove the access panel or cover to gain access to the transmitter.
2. Turn the aircraft master switch ON.
3. Tune the aircraft communications receiver volume up until a slight background noise is heard.
- NOTE -
If the aircraft is not fitted with a communications receiver, request
that the tower listen for your test.
4. On the transmitter, set the ON ARM OFF switch to the ON position. Keep the switch in this
position for only a few seconds: then set to the OFF position or ARM if there is no OFF. Return to the ARM
position.
-NOTE -
The test transmission should have been picked up by the aircraft
communications receiver and/or control tower. During cold
weather, there may be a slight delay before transmission occurs.
5. A transmitter which is functioning properly should emit a characteristic downward swept tone.
6. When the test is completed.ascertain the transmitter ON/ARM /OFFswitch is in the ARM position.
