á Place handset in charger.
For correct charging, be sure the room temperature is between 0°C/32°F and
40°C/104°F. 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, nothing indicates the
charging. There will be no reaction on incoming calls.
If the handset is turned on when charging, the display shows the blue charging
icon in the status bar. The charging icon is replaced by the green fully
charged icon , when the battery is fully charged (when handset is removed
from charger, the charging icon disappears). The handset will not vibrate. Auto
answer is inactive. The handset reacts normally for incoming calls.
It is necessary to recharge battery when display shows the battery low icon ,
or if the handset cannot be turned on.
