2) The following test procedure incorporates the steps necessary to confirm operation of the Dongle into
the “Installed Transmitter Test” procedure defined in the applicable ELT Description, Operation,
Installation & Maintenance Manual.
3) Remove the Dongle in accordance with Removal on page 17.
4) Change the position of the most significant bit (MSB) DIP switch. Refer to Figure 10 24-Bit Address
Switch Block on page 25.
5) Reconnect the Dongle in accordance with Installation on page 19.
6) Apply power to the ELT/Dongle, while the ELT remains off (i.e. inactive). Reprogramming takes place
within 30 seconds of power up.
7) Monitor the ELT for the next 2 minutes. Refer to the troubleshooting guidelines of the applicable ELT
Description, Operation, Installation & Maintenance Manual.
a) The LEDs on the ELT and remote switch will begin to flash rapidly if reprogramming was NOT
successful.
b) If the LEDs remain off after two minutes, the ELT has been reprogrammed.
8) Verify the 24-bit address has changed as a result of changing the position of the MSB DIP switch.
9) Repeat Steps 3 through 8 to return and verify the original configuration of the Dongle.
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 an Artex 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 Description, Operation, Installation & Maintenance
Manual for specific ELT registration information and instructions.
