3.3.3 Emergency Frequency
The GTN 750’s emergency frequency select provides a quick method
of selecting 121.50 MHz as the active frequency in the event of an in-flight
emergency. The emergency frequency select is available whenever the unit is on,
regardless of GPS or cursor status, or loss of the display.
To quickly tune and activate 121.50, press and hold volume
knob or the remote Com flip-flop key for approximately
two seconds.
NOTE: Pressing and holding the remote Com FLIP/FLOP key for
approximately two seconds, on units so configured, will lock the COM
board, preventing further changes in Com frequency until the Com board is
unlocked, by pressing the remote Com FLIP/FLOP key again for two seconds.
The following message will notify the pilot that the Com board has been
locked: “COM LOCKED TO 121.5 MHZ. HOLD REMOTE COM TRANSFER
KEY TO EXIT.”
NOTE: Under some circumstances if the Com system loses communication
with the main system, the radio will automatically tune to 121.50 MHz for
transmit and receive regardless of the displayed frequency.
