 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.
