“ACTIVE” state requires a positive switch transition from either the cockpit remote switch, ELT
local switch, or G-switch.
NOTE: It is possible the G-switch could activate the ELT as the result of severe maneuvers
or a very hard landing.

To take the ELT from an “ACTIVE” state back to an “INACTIVE” state, a “RESET” must occur.

A warning buzzer is required under C126 TSO approval. The buzzer is powered by the aircraft

approximately one second, and then moving it back to the “OFF” position. If the switch is
already in the “ON” position, move it to the “OFF” position.
