Replace upon reaching 50% of the expiration date printed on the battery casing. Replacement Procedure Highlights Turn the ELT control switch to the "OFF" position.
Initiate the self-test via the remote panel. The ELT will transmit a brief encoded test message to satellites (decoded as "test"). Verify with a 406 MHz test set or check the Cospas-Sarsat beacon registration website.
Turn the volume up so static or background audio is audible. Remove access panels and inspect the ELT 96

The casing separated with a satisfying sigh of released pressure. Inside, the architecture was beautiful. No circuit boards the size of thumbnails running cryptic code. Here, everything was tangible. Capacitors the size of shotgun shells. A transmitter crystal wrapped in copper. A rat's nest of color-coded wiring that followed a logic as old as the telephone.
A built-in self-test should be conducted regularly (e.g., every 6 months) to verify that the unit's electronics are functional. This test must be performed only during the first 5 minutes of any hour to avoid false alarms.
Required tool: Air Precision Test Jig, P/N: AP-TJ96.
Replace the battery if it has been used in an emergency or if it reaches 50% of its useful life (per FAA/EASA standards).
Check the exterior casing for any cracks or signs of impact. Ensure the mounting tray is secure; a loose ELT can lead to false triggers or damaged wiring during turbulence. 2. Battery Life Management
