Dear customer

Thank you for purchasing this product.

For optimum performance and safety, please read these instructions carefully.

The noise canceling function

Environmental noises in airplanes, trains, and buses, and noise caused by air-con- ditioners is reduced by a third, providing a quieter listening environment. This func- tion allows you to enjoy music without raising the volume too high, and is, therefore, kinder to your ears.

This unit mainly reduces the annoying low frequency sounds below 1500 Hz. For this reason, sounds with higher frequency portions, from car horns, telephones and human voices, remain relatively intact.

When to change the battery

The battery should be changed when the [OPR] indicator fades or fails to light. The noise canceling function becomes less effective as the battery wears down.

If the battery is worn down, or if a battery isn’t inserted at all, the unit acts like normal earphones.

Using the earphones

Turn down the volume on the audio equipment and insert the earphone plug (3.5 mm(1/8 in.) stereo) into the phone jack.

The earphone plug may not suit the jacks used on some aircraft.

Check the sides (L and R), then put the earphones on.

Start play on the audio unit and adjust its volume.

Turn on the noise canceling function.

Switch [OPR] to “ON”.

The [OPR] indicator lights.

Select the noise canceling level with [NOISE CANCEL].

Select “MAX” under normal circumstances. Select “MID” for a lower level of noise canceling.

Adjust the volume.

Volume changes when the noise canceling function is on. Adjust the volume with [VOLUME] on the controller or readjust the volume on the equipment.

You may have to change the position of the earphones to get the best noise cancel- ing effect.

Using the clip

Fit between the main unit and plug as close as possible to the main unit.
