Stuck Microphone

Whenever the GTN 750 is transmitting, a "TX" indication appears in the Com
window. If the push-to-talk key on the microphone is stuck or accidentally left
in the keyed position, or continues to transmit after the key is released, the Com
transmitter automatically times out (or ceases to transmit) after 30 seconds of
continuous broadcasting. You will also receive a "Com push-to-talk key stuck"
message as long as the stuck condition exists.
3.3.5

Remote Frequency Selection Control

On units configured for remote Com frequency Recall, pressing the remote
recall switch will load the next preset Com frequency into the unit' s Standby
frequency box. The remote recall switch can be pressed multiple times to scroll
the entire preset frequency list through the Standby frequency box (the list will
"wrap" from the bottom of the list back up to the top, skipping any empty preset
positions).
The standby frequency isn't activated until a Com FLIP/FLOP switch (either
bezel-mounted or remote (COM RMT XFR) is pressed. Remote Frequency Selection
only functions on units configured for a remote Com Frequency recall switch.
NOTE: Frequencies must be stored in the User Frequency List prior to
utilizing the remote channel select switch.
