Introduction
Getting Started
Fitting Your Headset
Fitting your headset properly is the key to
comfortable use and superior Active Noise
Reduction (ANR) capabilities. To gain peak
performance from the ANR feature it’s necessary
to have a solid seal around your entire ear
combined with a symmetrical t on your head.
The following tips will assist in achieving the
proper t.
A. Fit your ears entirely within the ear cups
providing a solid seal.
B. Rest the headband lightly on top of your
head with the right and left sliders extended
to equal lengths.

C. Position the microphone 1/8 inch from your
mouth. Speak into the microphone side labeled
“talk”which is marked at the microphone base.

Matching Stereo/Mono Setting to an Audio
Panel
The Stereo/Mono DIP switch setting should match
the signal from your audio panel. For a stereo panel,
best performance is gained by setting the headset
for stereo. The same is also relevant to a mono
panel. Incorrect settings result in communications
being heard in only one ear. The Stereo/Mono DIP
switch does not aect auxiliary devices, so you can
enjoy auxiliary audio in stereo regardless of how the
Stereo/Mono DIP switch is set.
