battery pack cannot be charged outside the permissible temperature value
range. The battery pack display then shows the temperature symbol. If the
display does not show anything during the charging process, please follow the
notes in the “Troubleshooting” chapter.
Note
The charging current and the necessary charging time is temperature-dependent
for safety reasons.

against spray water. Ensure that the battery pack engages correctly. With the
battery pack removed, make sure that no water gets on the electrical contacts
of the battery pack and the device. If there is water there, dry it
immediately (by wiping it off / shaking it out) and place the battery pack
with the contacts facing down so that the water can drain off. Do not use any
heat sources for drying.
