Inserting/Replacing The Batteries - Sennheiser Tourguide UHF Instructions For Use Manual

Inserting/replacing the batteries

For powering the radiomicrophone, you can either use two 1.5 V AA
size batteries or the rechargeable Sennheiser BA 2015 accupack.
Unscrew the display section
by turning it counter-clockwise.
Slide back the display section
Open the battery compartment cover
Insert the two batteries or the BA 2015 accupack as shown.
Please observe correct polarity when inserting the batteries/
accupack.
Close the battery compartment cover
Push the battery compartment into the radiomicrophone's body.
Screw the display section tight.
Note
For accupack operation of the radiomicrophone, 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
radiomicrophone 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, indivi-
dual rechargeable battery cells will not be identified as accup-
acks.
The monitoring of the accupack temperature during charging
in the L 2015 charger.
