FOUR | FEATURES AND USE

Using Your Headphones

1. If you intend to use the headphones for noise reduction only, simply turn the
power switch to the "ON" position. The LED on the controller will light. In this
mode, no cable connection is required.
2. Turn the power switch to "OFF" if noise reduction is no longer required. The unit
will then operate like normal headphones.
Noise cancelling headphones reduce unwanted ambient noise, providing a quieter
environment to enhance your listening experience. These headphones can be
used with or without the noise cancellation feature. Use the supplied plug-in
adaptor for easy connectivity to in-flight music services. Please use the shirt clip
on the back of the controller for secure and easy access to controls. For storage,
simply fold the ear cups in toward the headband and place in your travel pouch.
Connection to an Audio Source
You can use the headphones with a variety of audio sources such as CD, DVD, MP3
player, laptop computer or home stereo unit. To make a connection, simply insert
the headphone plug into the phone jack or the audio source.
1. Turn the power switch to "ON" and adjust the volume control to the desired
sound level. Note that the power indicator light is lit.
2. To stop the sound from the headphones temporarily, slide the mute switch to
the right as indicated by the arrow on the cabinet. To cancel the mute function,
slide the mute switch in the opposite direction.
3. Slide the power switch to the "OFF" position to turn off the unit after use.
