Getting Started 6
Charging a Battery
Your phone is powered by a rechargeable Li-ion battery. Use the
travel adaptor to charge the battery, and use only Samsung
approved batteries and chargers.
Note: You must fully charge the battery before using your phone for the first
time. A fully discharged battery requires up to 4 hours of charge time.
Note: For connection to an electrical supply not located in the U.S., you must
use an adaptor of the proper configuration for the power outlet. Use of
the wrong adaptor could damage your phone and void your warranty.
1. Plug the connector of the wall charger into the jack on the
side of the phone.
2. Plug the adaptor into a standard AC wall outlet. When
charging is finished, unplug the adaptor from the power
outlet.
3. Remove the adaptor from the charger port.
Note: You must unplug the adaptor before removing the battery from the
phone during charging to avoid damage.
Low Battery Indicator
When the battery is weak and only a few minutes of talk time
remain, a warning tone sounds and the “Battery Low” message
repeats at regular intervals on the display. The backlight turns off
to conserve the remaining battery power.
When the battery level becomes too low, the phone automatically
turns off.
Powering On or Off the Phone
1. Open the phone.
2. Press and hold the key or the key until the phone
power-on screen displays.
