A battery replacement date is marked on the transmitter label. To
comply with FAA regulations, 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.
When installed in the airplane, the ELT transmits through the antenna
mounted on the fuselage. The unit is also equipped with an integral portable
antenna to allow the locator to be removed from the airplane in an
emergency and used as a portable signal transmitter.
The locator should be checked during the preflight ground check to
make sure that it 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. Rearm the unit
and then recheck.
NOTE
If for any reason a test transmission is
necessary, the test transmission should be
conducted only in the first five minutes of any
hour and limited to three audio sweeps. If tests
must be made at any other time the tests should
be coordinated with the nearest FAA tower or
flight service station.
NARCO ELT 10 OPERATION
On the unit is a switch placarded “ON,” “OFF,” and “ARM.” the
“ARM” position allows the unit to be set to the automatic mode so that it
will transmit only after activation by 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 should be selected
whenever the unit is 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. The “OFF” position should be selected while changing the
battery or to discontinue transmission after the unit has been activated.
