intercom between the pilot and copilot is inhibited, although the pas-
sengers can still talk among themselves.
The crew intercom can be reactivated if desired by pressing the
“Mute” button. The indicator LED in the Mute button will be green
when the intercom is off (muted), and turn off to indicate that the in-
tercom is not muted, and the crew can speak to each other.
Swap Mode (Switch from Com 1 to Com 2 remotely)
With an optional yoke mounted, momentary switch, the pilot can
change from the current Com transceiver to the other by depressing
this switch. To cancel "Swap Mode," the pilot may either press the
yoke mounted switch again, or select a different Com with the XMT
buttons.
Audio Selector (4)
Navigation receiver audio is
selected through five momen-
tary, push-button, 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 la-
beled Nav 1, Nav 2, and MKR (Marker). DME audio (if present)
will come through when the Mon 2 button is selected. When one of
these buttons is pressed, the mode is active, and the LED will illumi-
nate. Press the switch again and it will be "off" and remove that re-
ceiver from the audio output.
In SPLIT mode, only the pilot will hear selected navigation audio.
Note: Split Mode does not turn off NAV, ADF, or AUX selected audio to
pilot. However, the copilot will only hear the selected com receiver and
unswitched inputs.
NOTE: Due to the nature of VHF communications signals, and the size
constraints in general aviation aircraft, it is probable that there will be some bleed-
over in the Split mode, particularly on adjacent frequencies. PS Engineering
makes no warranty about the suitability of Split Mode in all aircraft conditions.
