Installing the SIM Cards and the Battery
A SIM card carries useful information, including your mobile phone number, PIN (Personal Identification
Number), PUK (PIN Unlocking Key), IMSI (International Mobile Subscriber Identity), network information,
contacts data, and short messages data.
Charging the Battery
The lithium battery delivered with the mobile phone can be put into use immediately after being
unpacked. Your mobile phone can monitor and display the battery state.

Normally the remaining energy of the battery is indicated by the battery level icon at the upper right
corner of the display screen.

When the battery energy is insufficient, the mobile phone prompts "Battery low". If you have set an
alert tone, an alert tone will be given off when the battery level is too low.

A charging animation appears when the battery is being charged. When the charging is complete, the
animation disappears.

It is normal of the battery to become hot during the charging period.

The battery icon does no longer flicker when the charging process ends.

Use only the battery provided by the vendor. Otherwise, damages or even injuries could be caused
during the charging.

Power off the mobile phone before removing the battery.

The charging process lasts a longer time for a new battery or a battery not in use for a long time. If the
battery voltage is too low to enable the mobile phone to be powered on, charge the battery for a longer
time.
