TRANSCEIVERS
Audio from the #1 or #2 COM receiver can be selected independently by
pressing the respective Key(s) ( COM1 or COM2 ).
Pressing COM1 MIC or COM2 MIC selects the #1 or #2 transmitter
and simultaneously selects the related COM receiver (COM1 or COM2)
allowing received audio to be heard. The other COM receiver can be added
by pressing the respective key. When transmitting on the MIC selected
COM, audio from the other COM radio is muted.
SPLIT-COM MODE
NOTE:
Split COM performance is affected by the distance between
the COM antennas and the separation of the tuned frequencies. If the
selected COM frequencies are too close together, interference may be
heard during transmission on the other radio.
During Split-COM operation, both the pilot and the copilot can transmit
simultaneously over separate radios.
Pressing both MIC Keys simultaneously initiates Split-COM Mode.
The COM1/COM1 MIC and COM2/COM2 MIC in-key annunciators are
illuminated indicating Split-COM operation. Split-COM operation is
cancelled by pressing one of the selected MIC Keys again.
In Split-COM mode, the pilot uses COM1 and the copilot uses COM2
TRANSMIT INDICATIONS
During COM transmission, the active transceiver (COM1 MIC or
COM2 MIC) in-key Annunciator flashes approximately once per second.
During Split-COM transmission, the COM1 MIC annunciator flashes
when the pilot’s microphone PTT is pressed. The COM2 MIC annunciator
flashes when the copilot’s microphone PTT is pressed.
