We Recommend Alkaline AA Batteries.

Non-Alkaline Batteries Decrease

Available Operation 40% to 70%.

CAUTION: The FCC only allows the use of a cell phone within the cockpit when the plane is on the ground. By offering the cell phone interface on the control box, LightSPEED Aviation does not promote the use of your cell phone while in the air. If you choose to use your cell phone in the air, you do so in violation of FCC rules and at your own risk.The FAA has no position on the use of cell phones either while on the ground, or in the air. However, it is the duty of the pilot in command to be sure that electronic devices used in the plane do not conflict with the proper operation of the aircraft or its systems.

We don’t promise that this will work with all phones. Contact LightSPEED if yours does not.

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.

1Active 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”.

2Battery 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.

3Dual Volume Controls

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

4Aux 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 to anrheadsets.com to see about an adapter.

5Battery Test

By pressing the battery test button the battery status indicator light will show Green for good battery, or Red for 10% or less power left to run the ANR circuit.

6MONO/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.

7Comm Priority

Turning “On” Comm Priority will automatically mute 80% of the auxiliary audio signal. This allows the user to clearly hear radio intercom communications above any auxiliary audio in use. Positioning the switch to the right turns Comm Priority “On”, to the left turns Comm Priority “Off ”.
