SECTION 7
DESCRIPTION & OPERATION
ARTEX 110-4 ELT OPERATION
On the ELT unit itself is a two position switch placarded ON and OFF.
The OFF position is selected when the transmitter is installed at the factory
and the switch should remain in that position whenever the unit is installed in
the airplane.
A pilots remote switch, placarded ON and ARM is located on the left
hand side of the pilot's instrument panel to allow the transmitter to be armed or
turned on from inside the cabin. The switch is normally in ARM position.
Moving the switch to ON will activate the transmitter. A warning light located
above the remote switch will alert you when ever the ELT is activated.
Should the ELT be activated inadvertently it can be reset by either
positioning the remote switch to the ON then immediately relocating it to the
ARM position, or by setting the switch on the ELT to ON and then back to
OFF.
In the event the transmitter is activated by an impact, it can be turned off
by moving the ELT switch OFF. Normal operation can then be restored by
resetting the switch to ARM. It may also be turned off and reset by
positioning the remote switch to the ON and then immediately to the ARM
position.
The transmitter can be activated manually at any time by placing either
the remote switch or the ELT switch to the ON position.
Three sweeps of the emergency tone and an
illuminated warning light indicates a normally
functioning unit. The warning light must
illuminate during the first 3 second test period.
If it does not illuminate, a problem is indicated
such as a "G" switch failure.
The ELT should be checked during postflight to make certain the unit has
not been activated. Check by selecting 121.50 MHz on an operating receiver.
If a downward sweeping audio tone is heard the ELT may have been
activated. Set the remote switch to ON. If there is no change in the volume of
the signal, your airplane's ELT is probably transmitting. Setting the remote
switch back to OFF will automatically reset the ELT and should stop the
signal being received on 121.50 MHz.
