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.

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 oper- ational reliability. For charging the accupack, only use the L 2015 charger. Both the rechargeable battery and the charger are avail- able 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 nec- essary for the following control purposes:

yThe 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.

yThe monitoring of the rechargeable battery temperature during charging in the L 2015 charger.
