Charging the battery

The base station works as the battery charging unit. Charge the rechargeable battery before starting to use the headphones.
You can continuously use the headphones for about 10 hours after full battery charge.

1. Make sure that the headphones are turned off.
   You cannot charge the battery of the headphones when the headphones are turned on. Press POWER to turn the Power indicator off.

2. Put on the headphones on the base station so that their charging terminals contact firmly.

   • The battery charging terminal on the base station is covered with the protection cap when purchasing. Take off the cap before charging.
   • When putting the headphones on the base station, hold them and adjust their position with your both hands to assure the contact of the terminals.
     

Confirm the CHARGE indicator lights up.
If the charge indicator does not light up, return steps 1 and 2 after checking the connection of the AC adaptor.

• It takes about 30 hours to charge the batteries fully.
• 30-hour charging may not charge the battery fully depending on the battery or other conditions.
• The cycle life of the rechargeable battery is approximately 500 times. (It varies  depending on the conditions whencharging.)
• The battery leaks its charge little by little even when the headphones’ power is off, due to its characteristics.

Notes on the battery and charging

• To make battery life longer:

  • charging the battery within the temperature range of 10ºC – 35ºC (50ºF – 95ºF).
  • not using the headphones in excessively cold places. Low temperature decreases battery life.
  • charging the battery after its complete discharging. Charging before complete discharge makes the battery life gradually shorter.

• Replace the batteries when their lives become about half or the playback sound become constantly noisy.
  Use the exclusive rechargeable Ni-MH battery J47958 only. When purchasing the battery, consult the dealer where you bought the product.

• Replace two batteries at the same time when replacing

Basic operations

Listening to the sound from the base station

The base station works as the FM transmitter and send sound to the headphones.

Precaution

Turn down the volume of the headphones with the VOL dial before turning on its power to avoid excessive volume.

1 Start playback on the AV equipment connected with the base station.
The base station turns on automatically and starts to transmit FM signals (Auto Power On function).
The POWER indicator of the base station lights up.

• In some situations, the power may not be turned on automatically by the input sound (e. g. a song with a quiet opening or fade in). This is not a malfunction.

2 Press POWER on the headphones to turn on the power.

The POWER indicator lights up and the headphones automatically starts to tune in to the signal from the base station (Auto Tuning function). The AUTO SCAN indicator lights up when tuned in.

• Press the center of the button firmly when pressing POWER. Pressing the edge may not turn on the power.

• Charge the battery in the following cases.
  The battery ran out:

  • The POWER indicator does not lightup after pressing POWER.
  • The AUTO SCAN indicator does not light up though the POWER indicator lights up.
  • No sound is heard while Auto Tuning. It takes a few seconds to tune in.
  • Press AUTO SCAN when the sound does not come out properly.

Adjust the volumes of the AV equipment and the headphones.

• Adjust the volumes within the area about 7 m (23 ft.) from the base station to get optimum signal reception.
• You can get better sound by setting the volume of the AV equipment as high as possible without causing distortion and that of the headphone lower (except when connecting the AV equipment through LINE OUT jacks).

To Turn off the units
Press POWER on the headphones and stop playback on the AV equipment. The headphones’ POWER indicator goes off.

• The base station automatically turns off if no signals come in for about four minutes (Auto Power OFF function).
• The white noise may come out when the base station turns off. Take off and turns off the headphones after using.

Basic operations

Selecting a better reception channel

When the playback sound is noisy, you can choose one of the other two channels to transmit signals on the base station.

• The white noise may come out when switching the channel. Take off the headphones when switching the channel.

1. Slide the CHANNEL selector on the back side of the base station to select another channel.

2. Press AUTO SCAN on the headphones to tune in to the new channel.

3. Repeat Steps 1 and 2 to select the best channel.

Listening area

The headphones can receive the FM signal of the base station 50 m (164 ft.) away from it at maximum (when no interference or obstacles exist between them). But the receivable range becomes shorter or reception quality becomes poorer in the following cases:

• In places such as reinforced concrete buildings
• Obstacles such as steel-reinforced doors exist between the base station and headphones
• Items such as metal furniture are situated nearby
• In places facing a street
• Noise or interference sources exist nearby (e.g. mobile ham, radio stations, highvoltage power lines, a microwave oven, cordless phones, cellular phones, etc.)

Call through the base station

You can call the one using the headphones with the microphone on the base station.

1. Press and hold CALL on the base station.
   The playback sound is interrupted.

2. Speak to the microphone on the base station.
   Speak at least 10 cm (4 inches) away from the microphone. The speaking sound may be distorted.

3. Release CALL after finishing speaking.

   • Do not speak to the microphone suddenly in too loud voice. The sudden excessive loud sound may damage the ears of  the headphones user or may cause anaccident to the user.
   • Do not use the Call function when the headphones are near the base station. It may cause a howling sound and damage the headphone user or cause an accident.

Troubleshooting

What appears to be trouble is not always serious. Check the following points before calling a service center.

• Turns on the power of the headphones.
• Start playback on the AV equipment connected to the base station.
• Check the connection between the base station and the AV equipment.
• Turns up the volume of the headphones or the connected AV equipment to an appropriate level.
• Fully charge the headphones’ battery.

No sound comes out from R-channel.|

• Check the connection between the base station and the AV equipment.
• Sound comes out only of L-channel when the base station is connected to the monaural audio output. Convert the mini plug to the base station from stereo to monaural with the plug adaptor (not supplied).

Sound is distorted.|

• The headphones’ battery will soon run out. Fully charge the battery.
• The volume of the headphones and/or the connected AV equipment is too high. Adjust their volume to an appropriate level.

Sound is noisy|

• The headphones’ battery will soon run out. Fully charge the battery.
• Switch the base station channel to another and press AUTO SCAN on the headphones.
• The volume of the connected AV equipment is too low. Adjust the volume as high as possible without causing distortion.
• Too far from the base station. Use the headphones within the range of the base station

Cannot charge the battery|

• Check the contact of the charging terminals on the base station and the headphones.
• Check the polarity of the battery.
• The cycle life of the battery ended. Replace with the new battery.
