A.

15-Digit Hex ID Verification

(1) 15-digit hex ID verification should be performed any time an ELT 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/NAV Interface is powered up and has at least 30 seconds to initialize.
NOTE:
(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:
(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". A message
example is shown in "Figure 4. 406 MHz Location Message without Position Data", on
page 35.
(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.

The aircraft navigation system is NOT turned on for this test. For ELT
registration purposes, the 15 digit hex ID shall contain the "default" value of no
position data (i.e., always FFBFF)
A beacon reader equivalent to the ETS may be used, provided it is capable of
receiving and decoding the 406 MHz digital message.
