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.
3. 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 when charging.)
   • 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.

Troubleshooting

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

Symptom:  Cause/Remedy

No sound comes out at all.	• 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. • 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. Replace with the new battery.
