If the plug of the AC power adaptor does not fit in the AC outlet, use the supplied AC plug adaptor.

Notes

• Do not connect to the AUDIO IN A and B jacks at the same time. If you do so, the audio signals may be mixed.

• Use only the supplied AC power adaptor. Do not use any other AC power adaptor.

Polarity of the plug

• Keep the AC power adaptor cord as far away from the transmitter as possible. If the cord is positioned near the transmitter, noise may occur.

• When you connect the transmitter directly to a monaural earphone jack, the audio signal will not be output through the right channel. In such a case, use the separately sold PC-236HG plug adaptor.

• If the connected equipment has the AVLS (Automatic Volume Limiter System) function, be sure to turn the function off when using the transmitter. Otherwise, you will have to turn up the volume of the headphones, and that may cause noise.

4 Connect the AC power adaptor to an

AC outlet.

Charging the headphone batteries

When the charge indicator is not lit

Check the connection to make sure that the contact pins are properly fitted into the contact holes on the headphones, or if the headphones are rested on the transmitter correctly.

Using the headphones for the first time

When you use the headphones for the first time, charge the batteries in the following manner.

1 Connect the transmitter to a power

source.

2 Place the headphones on the

transmitter so that the charging pins on the transmitter engage the charging contacts on the bottom of the headphones. The CHG (charge) indicator on the transmitter will light in green to indicate that the batteries are being charged.

To recharge the headphone batteries after use

This system automatically stops charging by the built-in timer to prevent the risk of damage to the headphones due to overcharging. For this reason, we recommend that you rest the headphones on the transmitter whenever you do not use the headphones.

Mute function

If a hissing noise is heard when the infrared rays are obstructed, or the headphones are used outside of the effective range (see right column), the mute function will be activated and the sound will not be heard from the headphones. To restore the sound, move nearer toward the transmitter or remove the obstruction.

When no audio signal is received for more than approximately five minutes

The transmitter will be turned off automatically.

When an audio signal is intermittent or a low-level audio signal continues for more than approximately five minutes

The transmitter may be turned off automatically. In this case, turn up the volume of the connected equipment while turning down the volume of the headphones.

After listening to a program

Take the headphones off and rest them on the transmitter. Then turn off the connected audio/ video equipment. The transmitter power will be turned off automatically if no audio signal is input from the audio/video equipment for more than approximately five minutes.

Note

The infrared emitters light up when the transmitter is turned on. The brightness of the emitters may not be uniform, however, this is not a malfunction.

The effective areas of the transmitter

The illustration below shows the approximate area covered by the infrared rays emitted from the transmitter.

Approx. 4 m

(157

/2 in.)

Transmitter

Approx. 4 m (1571/2 in.)

Notes

• This system utilizes infrared rays for communication so noise (hissing) can be heard from the headphones as you move farther away from the transmitter. The sound will also be cutoff and noise will be heard if the infrared rays are blocked. These are characteristics of infrared ray communication and do not indicate malfunction.

• The infrared rays will not penetrate walls or opaque glass, therefore, be sure to stay within sight of the transmitter.

• When you use the headphones inside the area illustrated in the diagram, the transmitter can be placed in the front, behind or by the side of the listener.

• The sound you hear varies according to your position and the transmitter position. Try finding a position which yields the best sound.

• Do not cover the infrared sensors with your hands or hair.

The transmitter of another headphone system which does not employ the noise reduction system is used with the headphones of this system.

•Use the transmitter of this system.

Move closer to the transmitter. As you move away from the transmitter, more noise is likely to be heard. This is inherent to infrared ray communication and does not mean that there is a problem with the unit itself.

Check that there is no object between the transmitter and the headphones.

Check that the infrared sensors are not covered with your hands or hair.

Problem

Loud background noise

The batteries cannot be charged.

Solution

Change the position or angle of the transmitter.
