Charging the Battery
Pay attention to the mains voltage. The voltage of the
u
power source must match the voltage specified on the
rating plate of the charger.
The battery is equipped with temperature monitoring that al-
lows charging only in the temperature range between 0 °C
and 35 °C. In this manner, a high battery service life is
achieved.
Note: The battery is supplied partially charged. To ensure
full battery capacity, completely charge the battery in the
battery charger before using for the first time.
The lithium-ion battery can be charged at any time without
reducing its service life. Interrupting the charging procedure
does not cause damage to the battery.
The "Electronic Cell Protection (ECP)" protects the lithium-
ion battery against deep discharging. When the battery is
empty, the product is switched off by means of a protective
circuit: The product no longer operates.
Do not continue to press the On/Off switch after an auto-
matic shut-off of the product. The battery could become
damaged.
Observe the notes for disposal of the battery.
