ARROW

A battery replacement date is marked on the transmitter label. To comply with FAA regu-
lations, the battery must be replaced on or before this date. The battery must also be replaced if
the transmitter has been used in an emergency situation or if the accumulated test time exceeds
one hour, or if the unit has been inadvertently activated for an undetermined time period.
On the unit itself is a three position selector switch labeled "OFF," "ARM" and "ON."
The "ARM" position is provided to set the unit to the automatic position so that it will
transmit only after impact and will continue to transmit until the battery is drained to depletion
or until the switch is manually moved to the "OFF" position. The "ARM" 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. The "ON" position is provided so the unit can be
used as a portable transmitter or in the event the automatic feature was not triggered by impact
or to periodically test the function of the transmitter.
Select the "OFF" position when changing the battery, when rearming the unit if it has
been activated for any reason, or to discontinue transmission.
NOTE
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 "ARM" position.
A pilot's remote switch, located on the left side panel, is provided to allow the transmitter
to be controlled from inside the cabin.
I . On some models the pilot's remote switch has three positions and is placarded "ON,"
"AUTOIARM," and "OFFIRESET." T h e s w i t c h i s normally l e f t in t h e
"AUTOIARM" position. To turn the transmitter off, move the switch momentarily
to the "OFFIRESET" position. The aircraft master switch must be "ON" to turn the
transmitter "OFF." To activate the transmitter for tests or other reasons, move the
switch upward to the "ON" position a n d leave it in that position as long as
transmission is desired.
2. On other models the pilot's remote switch has two positions and i s placarded
"ONIRESET" and "ARM (NORMAL POSITION)." The switch is normally left in the
down o r "ARM" position. To turn the transmitter off, move the switch to the
"ONIRESET" position for one second then return it to the "ARM" position. To
activate the transmitter for tests or other reasons, move the switch upward to the
"ONIRESET" position and leave it in that position as long as transmission is desired.
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 121.5 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 insure against outside interference.
