Following a lightning strike, or an exceptionally hard landing, the
ELT may activate although no emergency exists. To check your ELT for
inadvertent activation, select 121.5 MHz on your radio transceiver and
listen for an emergency tone transmission. If the ELT can be heard
transmitting, place the function selector switch in the OFF position and the
tone should cease. Immediately place the function selector switch in the
