Inserting and replacing the batteries

For powering the plug-on transmitter, you can either use two 1.5 V
AA size batteries or the rechargeable Sennheiser BA 2015 accupack.
Slide the battery compartment cover
embossed arrow until it clicks audibly and open the cover.
Insert the two batteries or the BA 2015 accupack as shown
below. Please observe correct polarity when inserting the
batteries/accupack.
Close the battery compartment. The battery compartment cover
locks into place with an audible click.
Note:
For accupack operation of the transmitter, only use the BA 2015
accupack in order to ensure optimum operational reliability. For
charging the accupack, only use the L 2015 charger. Both the
accupack and the charger are available as accessories.
The accupack is fitted with an integrated sensor which is – via a
third contact – monitored by the electronics of the plug-on
transmitter and the charger. The sensor is necessary for the
following control purposes:
The taking into account of the different voltage characteristics
of primary cells (batteries) and accupacks. The battery status
indications on the displays, the transmission of transmitter
battery status information to the rack-mount receivers and
the switch-off thresholds at the end of the operating time are
corrected correspondingly. Due to the missing sensor,
individual rechargeable battery cells will not be identified as
accupacks.
The monitoring of the accupack temperature during charging
in the L 2015 charger.
