BATTERY INFORMATION
BATTERY TYPES AND SIZES
• Standard: Li-Ion 1000mAh
TEMPERATURE
Batteries function best at room temperature
(+20°C).
At temperatures below 0°C, use a battery which
is freshly recharged.
At temperatures below -25°C the battery will not
supply power and the phone cannot be used.
Upon warming up, the phone will function proper-
ly again.
Use of the phone is prevented at temperatures
above +60°C to ensure equipment safety. After
cooling off, the phone will function properly.
At room temperature (+20°C) the Li-Ion battery
loses more than 15% of its capacity in a month.
During the first two days the loss of a capacity is
usually several percent.
Higher temperatures will accelerate the discharg-
ing process.
EMPTY BATTERY
The battery symbol is located on the top row
of the display. The more “full” the symbol is, the
more charge is in the battery.
When the battery is almost empty a beep is heard
and the text
Battery low will be displayed.
If the display backlight is off, low battery may be
indicated by blinking red led. For more informa-
tion, see
selecting display settings on page 52.
When the battery is totally empty the power will
turn off. Charge the battery or replace it with a
recharged battery.
MAINS CHARGER
The mains charger should only be used indoors.
Make sure that the voltage in the country which
you are staying corresponds to the voltage (230
V) of the charger.
Plug the charger into a mains outlet. Charging
will start automatically.
The mains charger is usually provided with the
phone, but it is also available as an accessory.
