1.5 Charging Battery

When charging battery for the first time, it is necessary to leave handset in
charger for 14-16 hours for the battery to be fully charged.
During normal operation, it takes approximately 6 hours to charge the
handset from fully discharged to its full capacity. Turning the backlight off
reduces charging time with approximately 2 hours (refer to "Turning Back-
light Off" on page 59).
• 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 tempera-
ture 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.
