Charging the accupack

For charging the accupack, place the headphones into the transmitter’s charging compartment (nb: make sure the headphones are inserted the correct way round. The Sennheiser logo on the headband must be readable looking from the front - see diagram.

The charging contacts are on the RH earpiece of the headphones - these are placed on the corresponding contacts in the LH indentation of

the transmitter, the one next to the “charge” light.) The red LED on the transmitter must light up to show charging is taking place.

Always store the headphones on the transmitter to ensure that they are fully charged when they are needed. The headphones are automatically switched off by the charging process.

BA 151 spare accupack

When the headphones’ accupack is going flat (noise, interference and distortion are sure signs of a flat accupack), recharge the accupack. After an initial charging of 24 hours, the normal charging time is 14 hours. A fully charged accupack has an operating time of approx. four hours.

If you wish to use your headphones for more than four hours of continuous operation, we recommend purchasing a spare accupack. Always store the spare accupack in the charging compartment at the back of the transmitter to ensure that it is fully charged when it is needed. Only use original Sennheiser accupacks – accupacks from other manufacturers may cause damage to your headphones and will invalidate the guarantee.

Additional BA 151 spare accupacks can be charged via the L 151-2 charger (available from your specialist dealer).

Before disposing of an old and exhausted accupack, make sure that it is totally discharged by using it until the device switches off. To protect the environment, only dispose of totally exhausted accupacks.
