4. A transmitter which is functioning properly should emit a characteristic downward swept tone.
5. When the test is completed, ascertain the transmitter ON/ARM/OFF switch is in the ARM position.
6. Place the access panel on the right side of the fuselage aft of sta. 228.30.
Whenever the unit is checked by moving the transmitter
ON/ARM/ OFF switch from the ARM to the ON position, it must
then be moved to the OFF position before reverting to the ARM
position again.
Under normal conditions, the transmitter switch must be set to
arm.
TESTING PILOT'S REMOTE SWITCH.
Before performing any operational test of the pilot's remote switch, the same precautions noted in Testing
Emergency Locator Transmitter must be observed.
1. Tune the aircraft communications receiver to 121.5 MHz and switch the receiver ON, deactivate the
squelch, and turn the receiver volume up until a slight background noise is heard.
If the aircraft is not fitted with a communications receiver,
request that the tower listen for your test.
2. Set the pilot's remote switch to the ON position. Hold the switch in this position for only a few
seconds.
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.
3. Set the pilot's remote switch to the momentary OFF, RESET position. The switch is spring loaded to
automatically return to the ARM position.
