Using the Battery Note: This phone comes packaged with a partially charged rechargeable standard Li-Ion battery and wall charger. 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. Important!: Although the phone can be used while the battery is charging, the battery must be fully charged before first use, otherwise you could damage the battery. Battery Indicator The battery indicator in the upper-right corner of the display indicates battery power level. Four bars indicate a full charge, while an empty icon indicates an almost empty battery. Two to three minutes before the battery becomes too low to operate, a blinking empty battery icon appears and a tone sounds. If you continue to operate the phone without charging, it shuts down. Using A Non-Supported Battery Samsung handsets do not support the use of a non-supported battery. When using a non-supported battery you will hear a series of beeps and you will see a warning message that indicates "NON SUPPORTED BATTERY. SEE USER MANUAL" If you receive this warning, battery charging has been disabled. Samsung charging accessories (i.e. wall charger, and cigarette lighter adapter) will only charge a Samsung approved battery. To continue use of your handset press OK . Note: When using a non-supported battery the handset can only be used for the duration of the life of the battery and cannot be recharged. Important!: Using a non-supported battery may cause damage to your phone. Use a Samsung supported battery only. Getting Started 5
