NGM Forward 5.5 Guía Rápida página 38

The battery: your device is provided with a lithium ion battery and is designed to be used
exclusively with original NGM batteries and chargers. The battery is located in the back of
the phone and cannot be removed from its placement. To replace the battery, contact the
NGM Service Center. If a phone reboot is needed, e.g. when the phone is blocked, press
and hold power ON key for 15 seconds.
Charging the battery
Charge the battery before starting to use the device. Use the supplied USB cable and the
USB connector on the top side of the phone. Connect the charger to the provided wall
socket adapter, and then the device to the USB cable. You can also charge the phone by
connecting it with the PC USB port, but in this case charging will take longer. When the
battery is charging, an animated icon on the screen will show the charging progress if the
phone is on. Once the battery icon is filled, it is fully charged and the phone can be
disconnected from the grid.
Attention: Do not connect the phone to a booting-up or running down PC to avoid voltage
jumps. To preserve the functionality of the product and the integrity of the warranty, we
recommend the use of original NGM chargers. Please charge the battery indoors, in a dry
and favorable environment. It's normal for the battery to get slightly warm during the
charging process. The battery will reach its full capacity when cycled several times.
