3 Operation
3.1 Inserting or replacing the batteries
For power supply, two 1 5 V batteries of size
AA are required If the LED (2) shows red, the
batteries are discharged and should be replaced
•
Only insert batteries of the same type and
always replace both of them
•
If the microphone is not in use for a longer
period of time, always remove the batteries
as a precaution to prevent damage due to
battery leakage
1) To access the battery compartment (10), hold
the microphone head and screw off the screw
sleeve (4)
2) Open the battery holder (11) (pull hard to dis-
engage the battery holder), fig 2 on page 10
3) Insert the batteries with the positive and neg-
ative poles as indicated in the holder
4) Close the battery holder, making sure that
the holder engages; then screw on the screw
sleeve
3.2 Operation with
rechargeable batteries
Instead of non-rechargeable batteries, it is also
possible to insert two rechargeable NiMH (nick-
el-metal hydrate) batteries of size AA To charge
these batteries, the charging station 850CH-2 is
ideally suited: Leave the batteries in the micro-
phone and insert the microphone into a charg-
ing slot Power is supplied via the contacts at
the lower end of the microphone
Never put batteries in the household
waste Always dispose of the batteries
in accordance with local regulations
