Sennheiser RS 40 Notice D'emploi page 8

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.
