5. Main switch selection
“ON”

a. Set the main switch to “
ON
” to transmit immediately.
Both green ON lights will flash and the buzzer will
sound.
6. In the event of a crash, the AK-451 ELT activates
automatically, and transmits the standard swept tone on
243/121.5 MHz lasting until battery power is gone.
a. For the first 24 hours of operation, a 406 MHz signal is
transmitted at 50 second intervals. This transmission
contains identification data programmed into the ELT to
be received by COSPAS-SARSAT satellites.
b. If it is necessary to leave the scene of the accident, the
AK-451 may be removed from the aircraft and used as a
personal locating device.
7. Main switch selection
“OFF”
:
a. Set the main switch to “
OFF
” when handling or shipping
the beacon to avoid nuisance activation.
8. In case of an inadvertent activation, contact the local
National Authority to report false alarms. Any activation of a
406 MHz for a few seconds will usually be detected, and if no
actual emergency exists, will generate a false alarm.
