TYPES AND SIZES
There are two kinds of batteries available for this
phone:
•Li-Ion 900 mAh
•Li-Ion 1200 mAh.
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 properly
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 shown in the display. The
"liquid level" in the symbol shows how full the bat-
tery is.
When the battery is almost empty a beep is heard
and the text
Battery low
will be displayed.
When the battery is totally empty the power will
turn off. Charge the battery or replace it with a re-
charged battery.
