Charging
The battery can only be charged if inserted into the telephone. The charging
process is completely controlled by the mobile. Different kinds of Siemens chargers
out of the accessory program for C1x models can be used for this task:
a) Standard charger
b) Quick charger
c) Desk top charger (This device is not really a charger but a stand for
the mobile, where Standard- , Quick- or Travel charger are
connected to)
d) Travel charger
e) Car charger
Attention:
Charging the battery can be impossible, if the temperature is too high (e.g. in car use
during summer) or too low. This is to prevent the battery from being damaged during
fast charge process. To enable the charging process again, battery and phone only
needs to cool down/warm up. A replacement of battery is not necessary.
