C. 15-Digit Hex ID Verification
(1) 15-digit hex ID verification should be performed any time a Dongle is installed in an aircraft to
verify the ELT is properly labeled and registered.
(2) Perform the following procedure within the first 5 minutes after the hour (UTC), as required by
AC 43.13-1, Chapter 12, § 12-22, Note 3.
(a) Notify any nearby control tower of your intentions.
(b) Verify the ELT/Dongle is powered up and has at least 30 seconds to initialize.
(c) Set the 453-1000 ELT Test Set (ETS) beacon reader to receive and decode the ELT
digital message. Refer to the ETS operating manual (570-1000) for ETS operating
instructions and additional details.
NOTE: A beacon reader equivalent to the ETS may be used, provided it is capable of
receiving and decoding the 406 MHz digital message.
(d) Place the ETS within 30 feet of the aircraft 406 MHz antenna.
(e) Activate the ELT by placing the control switch or remote switch in the “ON” position.
(f) Allow the ELT to transmit for approximately 5 seconds.
(g) Deactivate the ELT and read the test message broadcast at “turn-off”.
NOTE: The ELT LED will flash 5 times to indicate a navigation data failure if a Cobham
Nav Interface Unit is not installed with the ELT. The Dongle does not support
the position data function of the ELT. If the ELT flashes other failure codes,
refer to the applicable ELT manual to troubleshoot the problem.
(3) The 15 digit hex ID (i.e., Beacon ID) displayed by the ETS is compared to the hex ID on the
ELT. If identical, no further action is necessary. If different:
(a) Enter the new hex ID on label P/N 591-0999 and affix it to the ELT over the existing hex
ID on the product label.
(b) If country and country code have changed, enter the new information on label (P/N 591-
0429-01) and affix it to the ELT over the existing information on the product label.
(c) Re-register the ELT. Refer to the applicable ELT abbreviated component maintenance
manual for specific ELT registration information and instructions.
