In order to ensure the longest possible service life for the rechargeable batteries, we deliver
them uncharged. Therefore, charge the supplied batteries before first operating
your headphones system.
The supplied batteries have been inserted into the headphones for your convenience.
If you operate the headphones on dry batteries, never try to charge the
batteries using the supplied charger. This would cause serious damage to your
headphones. Dispose of dead batteries conforming to local waste disposal
rules.
1. Use the POWER switch (1) to switch the headphones off.
When the power is off, the POWER LED (2) will be dark.
2. Plug the charging cable (7) into the charging socket (3) on the headphones.
3. Check that the AC voltage stated on the charger is the same as that availa-
ble in your country. If it is, connect the charger to a convenient AC outlet.
The status LED (8) will light to indicate the batteries inside the headphones are being
charged.
The batteries will be fully charged after approximately 14 hours.
4. Unplug the charging cable (7) from the headphones and disconnect the charger from the
power outlet.
In order to maintain full battery capacity for as long as possible, discharge the batteries com-
pletely about once a month:
1. Switch the headphones on and leave them on the shelf until the POWER LED (2) extin-
guishes.
2. Recharge the batteries.
The capacity of any rechargeable battery will decrease over time. If you feel that you need to
recharge the supplied batteries more often than would be convenient, you may consider
