Preparing for use

Inserting and changing the battery

For powering the radiomicrophone, you can either use two 1.5 V AA

size batteries or the rechargeable Sennheiser BA 2015 battery pack.

 Unscrew the display section  from the radiomicrophone’s

body  by turning it counter-clockwise.

 Slide back the display section  as far as it will go.

 Open the battery compartment .

 Insert the 9 V PP3 alkaline battery (IEC 6 LR 61) or the BA 2015

accupack. Please observe correct polarity when inserting the

battery.

 Close the battery compartment cover .

 Push the battery compartment into the radiomicrophone’s body.

 Screw the display section tight.

Note:

For rechargeable battery operation of the receiver, only use the

BA 2015 rechargeable battery In order to ensure optimum ope-

rational reliability. For charging the accupack, only use the L

2015 charger. Both the rechargeable battery and the charger are

available as accessories. The rechargeable battery is fitted with

an integrated sensor which is – via a third contact – monitored

by the electronics of the receiver and the charger. The sensor is

necessary for the following control purposes:

y 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.

y The monitoring of the rechargeable battery temperature

during charging in the L 2015 charger.
