To use the ELT as a portable unit in an emergency, remove the cover and unlatch the unit from its
mounting base. The antenna cable is disconnected by a left quarter-turn of the knurled nut and a pull. A
sharp tug on the two small wires will break them loose. Deploy the self-contained antenna by pulling the
plastic tab marked "PULL FULLY TO EXTEND ANTENNA." Move the switch to ON to activate the
transmitter.
In the event the transmitter is activated by an impact, it can only be turned off by moving the switch on
the ELT unit to OFF. Normal operation can then be restored by pressing the small clear plastic reset
button located on the top of the front face of the ELT and then moving the switch to ARM.
A pilot's remote switch optionally located on the left side panel is provided to allow the
transmitter to be turned on from inside the cabin. The pilot's remote switch is placarded "ON" and
"ARMED." The switch is normally in the ARMED position. Moving the switch to ON will activate the
transmitter. Moving the switch back to the ARMED position will turn off the transmitter only if the
impact switch has not been activated.
The ELT should be checked to make certain the unit has not been activated during the ground check.
Check by selecting 121.50 MHz on an operating receiver. If there is an oscillating chirping sound, the
ELT may have been activated and should be turned off immediately. This requires removal of the access
cover and moving the switch to OFF, then press the reset button and return the switch to ARM. Recheck
with the receiver to ascertain the transmitter is silent.
Select the OFF position when changing the battery, when rearming the unit if it has been activated
for any reason or to discontinue transmission.
If the switch has been placed in the ON position for any reason, the OFF position has to be selected before
selecting ARM. If ARM is selected directly from the ON position, the unit will continue to transmit in the
A pilot's remote switch, located on the left side panel, is provided to allow the transmitter to be controlled
from inside the cabin. The pilot's remote switch is placarded "ON," "AUTO/ARM" and "OFF/RESET."
The switch is normally left in the AUTO/ARM position. To turn the transmitter off, move the switch
momentarily to the OFF/RESET position. The aircraft master switch must be ON to turn the transmitter
OFF. To actuate the transmitter for tests or other reasons, move the switch upward to the ON position and
leave it in that position as long as transmission is desired.
The unit is equipped with a portable antenna to allow the locator to be removed from the aircraft in case
of an emergency and used as a portable signal transmitter.
The locator should be checked during the ground check to make certain the unit has not been accidentally
activated. Check by tuning a radio receiver to 121.50 MHz. If there is an oscillating sound, the locator
may have been activated and should be turned off immediately. Reset to the ARM position and check
again to ensure against outside interference.
NOTE
ARM position.
