24-Bit Address Reprogramming Verification Test

This test procedure verifies the ELT/NAV Interface has updated the aircraft 24-bit address ID in the
ELT programming.

programming takes place within 30 seconds of power up.
(2) Monitor the ELT for the next 2 minutes.
(a) The LEDs on the ELT and remote switch will begin to flash rapidly if reprogramming was
NOT successful. See Table 6, on page 38, for troubleshooting guidelines.
(b) If the LEDs remain off after two minutes, the ELT has been reprogrammed. Proceed to
