INADVERTENT ACTIVATION.
The remote switch allows the pilot to turn off the transmitter inadvertently activated by impact or improper
switch selection. The pilot simply selects the momentary OFF, RESET position. The transmitter shuts off and
the spring loaded switch automatically returns to the ARM position. The aircraft master switch must be ON to
turn transmitter OFF with the remote switch. Stopping inadvertent activation at the transmitter itself is
accomplished in the following manner:
1. Improper switch selection is corrected by rotating the switch to the OFF position and then to the ARM
position.
2. If the transmitter is inadvertently activated through impact, deactivate by pushing in on the
OFF/ARM/ON switch.
As a routine precaution, it is recommended that the ELT battery
be replaced at the earliest opportunity after inadvertent activation
and a functional test be made in accordance with Te s t i n g
Emergency Locator Transmitter. Note, however, that the problem
may not be in the transmitter. Check the following:
(1) Proper spacing of antennas so as to minimize antenna
conducted RF.
(2) Rigidity of the transmitter installation.
Under normal conditions, the pilot's remote switch must be set to
ARM position.
