etc.) will come through the speaker regardless of the speaker button posi-
tion.
Split Mode
The split mode can be activated at any
time by pressing the desired combination
of XMT buttons at the same time. For
instance, to activate a Com 1/Com 2 split,
press and hold the com 1 button, and then press the Com 2 button while
holding the Com 1 button. This places the pilot on Com 1 and the Copilot
on Com 2. All four indicator LEDs will be on.
Split mode is possible with pilot on Com 1, copilot on Com 2 or 3. Pilot on
Com 2 or Com 3 and Copilot on Com 1 is not possible.
Not e:
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.
Note
:
Split Mode does not turn off other (Nav, ADF, etc.) selected
audio to pilot. However, the copilot will only hear the selected
communications receiver.
Split Mode Intercom (ICS)
In split mode, the pilot and copilot are usually isolated from each other on
the intercom while using their respective radios. Depressing the
ICS
button
in Split Mode will activate VOX intercom between the pilot and copilot
positions. This permits intercommunication when desired between the
crew. Pressing the ICS button again turns off the crew intercom function.
Intercom Operation
IntelliVox
® VOX-Squelch
No adjustment of the
IntelliVox
® squelch control is necessary. There is no
field adjustment. Through individual signal processors, the ambient noise
appearing in all six microphones is constantly being sampled. Non-voice
signals are blocked. When someone speaks, only their microphone circuit
opens, placing their voice on the intercom.
The system is designed to block continuous tones, therefore people hum-
ming or whistling in monotone may be blocked after a few moments.
For consistent performance, any headset microphone must be
