5. Battery Replacement

The AVM2050 requires one 9 V battery. Alkaline batteries usually give
better results and last longer.
Warning: Do not puncture batteries or throw them in fire as
they may explode. Do not attempt to recharge non-
rechargeable batteries (alkaline). Dispose of batteries in
accordance with local regulations. Keep batteries away from
children.
1. Open the battery compartment and remove the old battery. Insert the
new one. Mind the polarity.
2. To test the battery, put the RANGE selector to BATT: if the meter
moves to the BATT TEST area, the battery is OK.
REMARKS:
 Set the RANGE selector to OFF when you are not using the AVM2050.
That way the battery will last longer.
 Remove the battery when you will not be using the AVM2050 for a
while.
6. Range
 Select 1 of the 7 measuring ranges (16 dB per range) using the RANGE
selector. The numbers refer to the zero point of each of the 7 ranges.
The pointer indicates the sound level compared to the reference value.
