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 ƹ.
̈ Insert the 9 V PP3 alkaline battery (IEC 6 LR 61) or the BA 2015
accupack. Please observe correct polarity when inserting the bat-
tery.
̈ Close the battery compartment cover ƹ.
̈ 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:
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,
individual rechargeable battery cells will not be identified as
accupacks.
y The monitoring of the rechargeable battery temperature
during charging in the L 2015 charger.
Changing the microphone module
̈ First remove the battery or the rechargeable battery and leave
the radiomicrophone open.
