The Safety of Your Ears is in Your Hands

Get the most out of your equipment by playing it at a safe level – a level that lets the sound come through clearly without annoying blaring or distortion and, most importantly, without affecting your sensitive hearing. Sound can be deceiving. Over time, your hearing “comfort level” adapts to higher volumes of sound, so what sounds “normal” can actually be loud and harmful to your hearing. Guard against this by setting your equipment at a safe level BEFORE your hearing adapts.

ESTABLISH A SAFE LEVEL:

• Set your volume control at a low setting.

• Slowly increase the sound until you can hear it comfortably and clearly, without distortion.

• Once you have established a comfortable sound level, set the dial and leave it there.

BE SURE TO OBSERVE THE FOLLOWING GUIDELINES:

• Do not turn up the volume so high that you can’t hear what’s around you.

• Use caution or temporarily discontinue use in potentially hazardous situations.

• Do not use headphones while operating a motorized vehicle; the use of headphones may create a traffic hazard and is illegal in many areas.

3 Playing music

1. When power is ON

When the power switch is set to ON, the power indicator lights green, and the noise-canceling function operates, allowing you to listen to music without excessively raising the volume, thus eliminating the need to raise sound volume excessively, and reducing disturbance to nearby people.

2. When power is OFF

When the power switch is set to OFF, the noise-canceling function stops, and the unit can be used as ordinary earphones.

3. When the monitor button is pressed

While the monitor button is held depressed, playback sound is muted and the noise-canceling function is temporarily stopped, thus allowing you to hear ambient sounds without removing the earphones.

* This function is enabled only when the power switch is set to ON.

4 Following Use

When not using the earphones, set the power switch to OFF.

5Precautions

• When disconnecting the cord, grasp the plug and do not pull the cord.

• The furnished in flight plug adapter may not be compatible with the jacks on all airplanes.

• Do not use with airline onboard sound systems under the following conditions:

– Whenever the cabin crew announces that electronic

devices are prohibited.

– When the use of privately owned earphones is prohibited

inside the plane.

• The noise-canceller function is designed to reduce noise primarily in the low-frequency range, and is not effective at reducing high-frequency noise.

• If the earphone tips do not correctly match the size and contours of your ears, excessive sound may escape, or you may sense insufficient bass sound, and the effect of the noise-canceling function may be reduced. Always select and use the earphone tips that best match the size of your ears.

• If the earphones’ microphone is covered with your hand or other object, feedback may be caused, resulting in a “howling” sound. In this case, remove your hand or other obstruction from the microphone.

English

Troubleshooting

If you suspect a malfunction, perform the following checks, since a simple operating error may be the cause of the problem. The problem may also be caused by factors other than the earphones themselves, so be sure to check the sound components with which the earphones are used.
