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.
