Chargers
Desktop charger
The desktop charger is used for charging your phone, but also for
storing it when you are continually at one location, for example at
your desk.
The tilted design facilitates the use of handsfree operation, i.e. in
loudspeaking mode. The charger is delivered with a plug-in power
supply and is connected to an ordinary wall socket.
Note:
Do not use the charger outside the temperature range of
+5 - +40 ºC.
Do not use other power supplies than originally delivered
(see “ Power adapters ” on page 127).
