(a)). It is important to have the microphone element parallel to your mouth,

and not twisted inside the cover.

Note: For optimum microphone performance, we recommend use of a Mi-

crophone Muff Kit from Oregon Aero (1-800-888-6910,

www.oregonaero.com

). This will not only optimize VOX performance, but

will improve the overall clarity of all your communications.

You should also keep the microphone out of a direct wind. Moving your

head through an air stream may cause the IntelliVox® to open momentarily.

This is normal. The IntelliVox® is designed to work with normal aircraft

cabin noise levels (70 dB and above). Therefore, it may not always recognize

speech and clip syllables in a quiet area, such as in the hangar, or without the

engine running. This is also normal.

Intercom Volume Control (7)

The small volume control knob adjusts the loudness of the intercom for the

pilot and copilot. It has no effect on selected radio levels, music input levels

or passengers' volume level.

The larger, outer volume control knob controls intercom volume for the pas-

sengers. It has no effect on radio or music levels.

Mono Headsets in Stereo Installation

The pilot and copilot positions work with stereo or mono headsets. If a mon-

aural headset is plugged in to a PMA8000BT Stereo installation, one channel

will be shorted and all passengers will lose one channel unless they switch to

the “MONO” mode on the headset.

Intercom Modes (8)

The intercom has three modes. The description of the intercom mode func-

tion is valid only when the unit is not in the "Split" mode. Then, the pilot and

copilot intercom is controlled with the Mute button.

This button cycles through the intercom modes, from top to bottom and then

back up.

SO: The pilot is isolated from the intercom and is

connected only to the aircraft radio system. He

hears the radios (and sidetone during radio trans-

missions). The copilot and passengers will hear the

music sources as configured by the audio panel

configuration Function keys. See page 11—Smart

Function Keys for more details.

While in ISO Mode, the pilot can elect to hear music #1. First, be sure that

the ISO mode is selected. Then press and hold the TEL button, then hold the

ICS mode button for more than one second. The ICS indicator will blink

slowly to indicate music is present in ISO. The music muting will be the

selected mode.
