Split Mode

The split mode can be activated at any time by pressing the desired combination 
of XMT buttons. 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 but-
ton. This places the pilot on Com 1 and the Copilot on Com 2.

Split mode for Com 3, in normal (not TEL/Duplex) 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. 

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. UPS Aviation Technologies 
makes no warranty about the suitability of Split Mode in all aircraft conditions. 

Split Mode does not turn off other (Nav, ADF, etc.) selected audio to 

pilot

. How-

ever, the copilot will only hear the selected communications receiver. 

1.5.1

Split Mode ICS

In split mode, the pilot and copilot are usually isolated from each other on the 
intercom while simultaneously 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 disables this crew intercom function.

Intercom Operation

1.6.1

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 humming or 
whistling in monotone may be blocked after a few moments.

For consistent performance, any headset microphone must be placed within ¼-
inch of your lips, preferably against them. (ref: 

RTCA/DO-214, 1.3.1.1 (a

)). 

It is also a good idea to keep the microphone out of a direct wind path. Moving 
your head through a vent air stream may cause the 

IntelliVox

® to open momen-

tarily. This is normal. 

The 

IntelliVox

® is designed to work with normal aircraft cabin noise levels (70 

dB and above). It loves airplane noise! Therefore, it may not recognize speech 
and clip syllables in a quiet cabin, such as in the hangar, or without the engine 
running. This is normal. For optimum microphone performance, UPS Aviation 
Technologies recommends installation of a Microphone Muff Kit from Oregon 
Aero (1-800-888-6910). This will not only optimize VOX performance, but will 
improve the overall clarity of 

all

 your communications.
