Note
To ensure that the charge level indicator works correct-
ly, the battery pack must be discharged during initial use
until the device is switched off.
Note
New battery packs are only pre-charged and must be
completely charged prior to the initial use.
The display is activated during the first charging pro-
cess.
CAUTION
Risk of injury, risk of damage due to exploding battery!
Only charge the battery packs with the appropriate
charger.
Note
If the display does not show anything when the battery
pack is in the charger, the battery capacity is fully de-
pleted or very low. As soon as the battery pack has
been sufficiently charged, the display shows the re-
maining charging time.
If the display does not show anything even after a
long period of time, the battery pack is defective
and must be replaced.
Note
New battery packs reach their full capacity after approx.
5 charging and discharging cycles.
Charge batteries that have not been used for a long time
before use.
The performance of the battery pack is reduced at tem-
peratures below 0°C.
The capacity of the battery pack may be reduced if
stored at temperatures over 20°C.
CAUTION
Risk of personal injury or damage! Ensure that the bat-
tery pack properly snaps into place.
