4.2 Installing Memory Card
The memory card is a pluggable mobile storage card inside the mobile phone.
To install the memory card, insert the card into the card slot.
To remove the memory card, take the card out.
Note:
1. The mobile phone cannot automatically identify the memory card being inserted when the mobile phone is powered on. You must
power off the mobile phone and then power it on, so that the phone can identify the memory card.
2. The memory card is a miniature object. Keep it out of the reach of children for fear that children swallow it!
4.3 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.
● When the battery level is too low, a beep will sound, a "Low Battery shutdown" message will
be displayed, and the power will be turned off.
● A charging animation appears when the battery is being charged. When charging is
completed, the animation disappears and a charging completed message pops up.
Using a travel adapter:
● Install the battery into the mobile phone before charging the battery.
● Connect the adapter of the travel charger with the charging slot in the mobile phone.
Ensure that the adapter is fully inserted.
● Insert the plug of the travel charger to an appropriate power outlet.
● During the charging, the battery level grids in the battery icon keep flickering till the
battery is fully charged.
● It is normal when the battery is become hot during the charging period.
● The battery icon does no longer flicker when the charging process ends.
Note: Ensure that the plug of the charger, the plug of the earphone, and the plug of the USB cable are inserted in the right direction.
Inserting them in a wrong direction may cause charging failure or other problems.
Before the charging, ensure that the standard voltage and frequency of the local mains supply match the rated voltage and power of the
travel charger.
Using the Battery
The performance of a battery is subject to multiple factors: radio network configuration, signal
strength, ambient temperature, chosen functions or settings, phone fittings, and the voice, data
or other application mode you choose to use.
To guarantee the optimal performance of your battery, please stick to the following rules:
● 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
long. If the battery voltage is too low to enable the mobile phone to be powered on, charge
the battery for a longer time. In this case, the battery icon does not flicker until a long time
after the battery enters the charge status.
● During the charging, ensure the battery is placed in a room temperature environment or
in an environment close to room temperature.
