3. Test Procedures
SUBTASK 25-69-01-990-001
A. General
CAUTION: ANY ELT RUNNING V133 SOFTWARE (SEE PRODUCT LABEL) MUST BE TESTED IN AN
RF CONTAINER, SCREEN ROOM, OR CONNECTED TO A DUMMY LOAD VIA THE
ANTENNA COAX CONNECTION, BECAUSE THE V133 SOFTWARE TRANSMITS A FIXED
TEST MESSAGE AT ELT RESET, NECESSITATING A “LIVE” BROADCAST TO READ THE
ACTUAL MESSAGE. ANY ELT RUNNING V134 OR V135 SOFTWARE TRANSMITS THE
ACTUAL 406 MHZ MESSAGE AT RESET AND MAY BE TESTED IN SITU.
(1) This task consists of two subtask testing requirements:
(a) 24-bit address programming test, which verifies ELT/Dongle 24-bit address
reprogramming functionality by initiating reprogramming and checking for the address
change or an error indication.
(b) 15-digit hex ID determination, which reads the programmed hex ID, country, and
country code broadcast in the 406 MHz message and provides instructions for relabeling
and re-registering the ELT, as applicable.
SUBTASK 25-69-01-750-002
B. 24-Bit Address Reprogramming Verification Test
(1) This is a recommended periodic test.
NOTE: This test procedure verifies the ELT/Dongle has updated the aircraft 24-bit address
ID in the ELT programming.
(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
abbreivated component maintenance manual.
(3) Remove the Dongle in accordance with “Removal” on page 27.
(4) Change the position of the most significant bit (MSB) DIP switch, refer to "Figure 10. 24-Bit
Address Switch Block", on page 38.
(5) Reconnect the Dongle in accordance with “Installation” on page 29.
(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 abbriviated component 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.
