Note!
Removing the Batteries During Periods of Non-Use
The integrated quartz movement draws power from the
batteries even when the instrument is switched off. It is
advisable to remove the batteries during long periods of
non-use for this reason (e.g. vacation). This prevents
excessive depletion of the battery, which may result in
damage under unfavorable conditions.
Note!

Make sure that no battery leakage has occurred before initial
start-up, as well as after long periods of storage. Continue to
inspect the batteries for leakage at short, regular intervals.
If battery leakage has occurred, carefully and completely clean the
electrolyte from the instrument with a damp cloth, and replace the
battery before using the instrument.
If the “ ” symbol appears at the display, the batteries should
be replaced as soon as possible. You can continue working with
the instrument, but reduced accuracy may result.
The instrument requires two 1.5 V batteries in accordance with
IEC R 6 or IEC LR 6, or two equivalent rechargeable NiCd
batteries.
