During normal operation, it takes
approximately 3.5 hours to charge the
handset from fully discharged to its
full capacity.
• Place the handset in the charger.
For correct charging, be sure the
room temperature is between 0°C
and 25°C. Do not place the
handset in direct sunlight. The
battery has a built-in heat sensor
which will stop charging if the
battery temperature is too high.
If the handset is turned off when
placed in charger, only the LED
indicates the charging. When
handset is turned off, the LED
flashes at a low frequency while
charging and lights constantly
when the charging is finished.
There will be no reaction on
incoming calls.
