Monitor Mode
Press and hold COM2 for more than two seconds to activate and deactivate
Monitor mode; an audio annunciation will report changes to the Monitor
mode status.
In Monitor mode, the audio from the radio selected for transmit will mute the
other Com radio.
For example, if Com 1 is selected to transmit to Air Traffic Control and Com 2
is receiving weather information, the audio from the weather will be muted
while Air Traffic Control is transmitting.
When Monitor mode is on, the indicator lamp of the radio selected for receive
only will blink every three seconds.
Monitor mode is not available in Split mode and is defaulted to off when the
audio panel is turned on.
Telephone Mode
The Telephone mode serves as a full duplex interface and distribution for
telephone systems such as mobile phones with earpiece jacks or Bluetooth
connectivity.
Pressing the Telephone button connects the telephone to the users as follows:
In PILOT intercom mode, only the pilot will hear the telephone, and
only they will be heard. No telephone sidetone can be created in
PILOT Mode; selecting PILOT mode during a call will cause the
sidetone, if present, to disappear.
In ALL intercom mode, all crew and passengers will hear and be heard
on the phone when they speak.
In CREW intercom mode, only the pilot and co-pilot are connected
to the telephone, passengers will not hear or be heard on the call.
Com and other selected radio audio is also heard in the headsets as specified
by the Intercom mode. The radio PTT will switch the microphone output to the
selected radio and allow continued aircraft communication. The telephone
party will not hear Com radio communications, and vice versa.
A phone call can only be initiated from the phone itself.
In cases where the mobile phone doesn’t provide sidetone, the audio panel
can be configured, by holding the TEL button for more than one second, to
create sidetone for you.
Trig recommends the use of mobile devices in a way that maintains safe flight
operations and good airmanship at all times.
Bluetooth®
A Bluetooth-enabled mobile phone must first be paired with the TMA45
before it can be used wirelessly for making calls or streaming music.
