DESCR/OPERATION
7.39 EMERGENCY LOCATOR TRANSMITTER. (continued)
NARCO ELT 910 OPERATION
On the ELT unit itself is a three position switch pJacarded ON, OFF and
ARM. The ARM position sets the ELT so that it will transmit after impact and
will continue to transmit until its battery is drained. The ARM position is
selected when the ELT is installed in the aitplane and it should remain in that
position.
A
pilot's remote switch, placarded ON and
ARM,
is located on the left
side panel to allow the transmitter to
be
armed or turned on from inside the
cabin. The switch is normally in the ARM position. Moving the switch to ON
will activate the transmitter. A warning light, located above the remote switch,
will blink continuously whenever the ELT is activated.
NOTE
The warning light will not blink if the ELT is
activated by an incident that also results in
severance of the airplane's pOwer supply lines.
Should the ELT be activated inadvertently it can be reset by either
positioning the remote switch to the ON position for two seconds, and then
relocating it to the ARM position, or by setting the switch on the ELT
to
OFF
and then back to ARM.
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 position for two seconds, and then 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.
The ELT should
be
checked duriilg 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 tone it is probably
you. Setting the remote switch back
to
ARM will automatically reset the ELT.
