Battery Control Box

All controls for the unit are contained in a small, inline audio control box.This should make it
easy to locate, even if it’s on the floor next to your intercom.

Active Cancellation ON/OFF Button

This button, when depressed, will activate the active circuitry in each dome for canceling
low frequency ambient sound. It functions with a Push “ON”, Push “OFF” motion. A green
flashing light indicates “ON”.

Battery Status Indicator

When the active circuitry is “ON” the LED button will flash green. When battery power
falls to 10% capacity for powering the ANR circuit the LED button will change to flashing
red indicating you have 2 hours or less of battery power to run the ANR system.

NOTE:Should batteries expire, the headset will still function with Audio and Comm.
The ANR and the AUX Audio will no longer operate.

Dual Volume Controls

These controls provide separate volume levels in each ear cup. Move the slide switches
up and down to change the volume levels.

Aux Audio Input

The Aux Audio input allows you to plug in personal audio devices such as Portable
CD Players, MP3 Players, Audible Checklists or Cell Phones.Your headset is supplied
with a 2.5mm patch cord, the evolving standard for hands free headsets in the cell phone
market.This patch cord will plug directly into most phones. If yours does not, please go

for good battery, or Red for 10% or less power left to run the ANR circuit.

MONO/STEREO Control

Your XLc headset can be used compatibly with either a Monaural or Stereo intercom
system.With the slide switch in the right position, it is Monaural. When moved to the left,
it is in Stereo.

If you are only receiving audio in one ear, move the slider to the right.

Ear Shape / Size and the
Opening of the Ear Seal

The seal opening is designed to fit comfortably around
most ears. Care should be taken to make sure each ear
is completely inside the seal…not pinched underneath!
If necessary, adjust the domes slightly to make sure the
ear lobes are tucked up inside the ear seals. With the
ears fully enclosed, the domes can deliver maximum
comfort and attenuation.

Dome

center of head

Minimal

pressure on jaw

Height Adjustment

Optimal fit is achieved by:

(1) Getting your ears positioned INTO the dome as described above.

(2) Holding either dome with one hand, slide the dome up the stirrup

rails until domes are slightly above your jawbone.

(3) Repeat this for the other dome.When completed, there should be

just a slight upward pressure on the bottom of your ear lobe.

Mic Positioning

The microphone element has a front and a back. Speak into the side that
says ‘TALK’ (see Fig. 1). The microphone is positioned for use on your left
side. The back side has an adjustable ‘GAIN’ pot. It is preset at our facility
for optimal performance. Should you need to adjust the output, contact
