Inserting and charging the accupack
The receiver can also be powered via the rechargeable
Sennheiser BA 2015 accupack. Insert the accupack into the
battery compartment as described above.
The receiver has two charging contacts
ᕥ
and a sensing
contact on its short sides. The accupack can be recharged while
remaining in the receiver. Insert the receiver into the L 2015
charger (see operating manual of the L 2015 charger).
Note:
For accupack operation of the receiver, only use the
BA 2015 accupack in order to ensure optimum operational
reliability. Batteries and rechargeable battery cells have
different discharging curves. The receiver is able to identify
the BA 2015 accupack and to use its capacity to the full.
Individual rechargeable battery cells will not be identified
as accupacks.
