(5) Activate the ELT by placing the cockpit remote switch in the “ON” position. The LED will begin
flashing continuously.
(6) Listen for 3 audible sweeps on the receiver, which takes about 1 second.
(7) Verify the buzzer sounds immediately upon activation.
(8) Return the cockpit remote switch to the “ARM” (off) position while paying close attention to
LED activity when the ELT enters the “ARM” condition. If the ELT is working properly, the LED
will stay on for approximately 1 second and then turn off.
NOTE: This test also completes the requirement to check ELT controls by verifying operation
of the remote switch.
(9) Refer to Table 6 on page 43 if the LED displays a series of error code flashes.

Q. Antenna Test – Item 7
CAUTION: DO NOT ALLOW THE DURATION OF THIS TEST TO EXCEED 5 SECONDS.
(1) Tune a low quality AM receiver (i.e., radio) to 121.5 MHz.
NOTE: The aircraft transceiver is not recommended for this test, because it is too sensitive
to verify the integrity of the antenna system and it may pick up a weak signal even if
the antenna is disconnected from the ELT. An AM radio provides a better level of
confidence for this test.
(2) Place the radio approximately six inches from the antenna.
(3) Activate the ELT by placing the cockpit remote switch in the “ON” position.
NOTE: Perform this test within the first five minutes after the hour UTC.
(4) Listen for 3 audible sweeps on the radio, which takes about 1 second. An audible signal
verifies energy is being transmitted by the antenna.
(5) Reset the ELT by placing the cockpit remote switch in the “ARM” position.
NOTE: The ELT contains an internal self test function that executes on deactivation of the
ELT. This self test function is designed to test the integrity and radiated power of the
ELT, coax cable, and antenna. If no LED error codes are displayed after deactivation
of the ELT, it is in compliance with FAR Section 91.207 subsection d paragraph (4).

R. Inspection and Test Documentation – Item 8
(1) Make an appropriate entry in the aircraft maintenance records (i.e., logbook), including the
date the ELT inspection and testing was satisfactorily completed.
(2) In addition to the requirements of Step 1, for aircraft operating under Canadian authority and
following satisfactory completion of performance testing, the date on which the test was
performed shall be marked on the ELT external casing in a legible and permanent manner.
