3 Split Mode
The split mode can be activated at any time by pressing the
COM 1 and COM 2 XMT buttons at the same time. This places
the pilot on C
OM 1 and the copilot on COM 2. Both green
switch LEDs are lit.
4 Audio Selector
Navigation receiver audio is selected through three momentary,
pushbutton, backlit switches. You will always hear the audio
from the selected transceiver.
The users can identify which receivers are selected by noting
which green switch LEDs are lit. Navigation aid audio push
buttons are labeled
Nav 1, Nav 2, and MKR (Marker). If DME is
present, it will be controlled by the
Mon 2 button. When one of
these buttons is pressed, the mode is active, and the LED will
illuminate. Press the switch again and it will be "off" and
remove that receiver from the audio output.
In SPLIT mode, only the pilot will hear selected navigation
audio.
5 Monitor Function
The
Mon 1 button allows the pilot to listen to the standby
frequency of COM 1 selected by the Avidyne Entegra
Control/Display Unit.
6 Telephone
The TEL mode serves as a full duplex interface and distribution
for portable cellular phones with earpiece jacks. Pressing the
TEL button activates the telephone mode.
7 Speaker Amplifier
The
SPR in the lower right section stands for speaker. This
switch will place all selected audio on the cockpit speaker when
this switch is selected.
All important audio annunciations (refer to Section 1) will come
over the speaker even if it is not selected.
8 Public Address Function
To access PA function, press the
Mute and SPR buttons
simultaneously.
