Installing/removing the battery

Your device is provided with a lithium-ion battery and is designed to be used exclusively with original NGM

batteries and chargers. Battery must be inserted from the backside of the phone. Loosen the screws and remove

the battery cover of the phone; then, align the battery contacts with the phone connector inside the dedicated

slot, and let it slide down in position. Once the battery is inserted, close the rear cover and tighten the screws.

Note: do install the battery as per the diagram to prevent the battery contact patch being damaged.

Battery Charging

Charging/recharging the battery

Please charge completely the battery before starting to use the device. The new battery cannot reach the optimal

efficiency unless it has undergone several continuous complete charges and discharges.

Use the USB cable provided, and connect it one end to the USB connector placed on the right side of the phone,

and the other end to the wall socket adaptor.

When the battery is used up, charge it in time. Over-discharge can damage the battery.

After the battery is charged full, cut off the connection of charger with the AC power supply and the connection

with the mobile phone.

When battery is charging, an animated icon on screen will show the charging progress. Once the progress bar is

completed phone can be disconnected from the grid.

Note: Use only the provided USB cable for recharging the device. Charge the battery indoors in a dry and

favourable environment. It's normal for the battery to get slightly warm during the charging process.

Warning: use only original accessories to charge the battery. The use of other accessories may damage your

mobile phone and cause risks!
