Battery
Problem Possible causes/consequences and M Solutions
The charge indicator
on the control console
is not showing that the
battery is "full" even
though a full battery
charge has been per-
formed.
The battery has been affected by the ambient temperature. The
battery heats up during the charging procedure.
X
Let the battery cool down and repeat the charging process.
X
Follow the instructions for charging the battery.
The charge indicator
on the control console
is not reliably dis-
playing the charge
level.
Due to frequent and brief charging and discharging of the
battery, the synchronisation between the charge indicator and
the actual battery charge level cannot be calibrated.
X
Perform a full discharge after approx. 30 charge cycles.
This will calibrate the charge indicator to the charge level
of the battery. The service life of the battery will not be
affected by this.
