Charge the battery
Your battery has been precharged, but the charging levels may vary.
1. Connect the charger to a wall outlet.
2. Connect the charger to the device.
3. When the battery is fully charged, disconnect
the charger from the device, then from the
wall outlet.
If the battery is completely discharged, it may
take a few minutes before the charging indicator
appears on the display or before any calls can be
made.
The charging time depends on the charger used.
Charging a BL-4CT battery with the AC-4 charger
takes approximately 1 hour 30 minutes while the phone is in the standby mode.
