A. Self-Test Error Troubleshooting Guidelines
(1) Table 6 describes the ELT self-test LED error codes (i.e., flash codes), their probable causes,
and possible solutions. The 5-flash error is not present when the ELT is programmed with a
serial user protocol (short message).
NOTE: Upon activation, the LED will display a long single flash, which is normal. Any self-
test error codes will display following this initial flash. Do not confuse the initial flash
with a 1-flash error code. If there are multiple errors, there is a 0.5 to 1.0 second
pause between each error code.
