4.3 Installing memory card

 

Since the mobile phone doesn’t have enough space, you may need to install a memory card (T-FLASH card).   

  To install the T-FLASH card: open the rear cover, take out the battery, insert the T-FLASH card into the slot, install the 
battery and then turn on the mobile phone.   

To remove the T-FLASH card: open the buckle and take out the T-FLASH card, and then lock the buckle.   

Note:    T-Flash card is tiny. Please keep it away from children.   

 

 

Note: Please select qualified T-FLASH cards, such as SANDISK, V-DATA, and Transcend. Please match with the mobile phone 

when you purchase the card.   

 

4.4 Battery and charging 

Installing the battery 

Only use qualified battery and accessories. When the battery isn’t used, put it in the protective case.   

Note: Please operate according to the figure to avoid damaging the battery contact.   

Charging the battery 

The new battery will reach its optimized performance after complete charging and discharging for several times.   
Please charge in time when the battery voltage is low. Over discharging will damage the battery.   
Disconnect the charger from the AC power supply and the mobile phone after charging.   

While charging, the battery status icon flashes from left to right, and stops flashing after charging.   
It is normal that the battery becomes warm in the charging process.   

Battery status 

Your mobile phone can monitor and display the battery status.   

1> 

You can check the battery status from the icon in the upper right corner of the screen.   

2> 

If the electricity is insufficient, the “Low Battery” prompt shows up. The mobile phone sends warning tone if the “Alert 

Tone – Warning Tone” in Profiles is activated. 

 

3> 

During charging, the icon of battery status blinks until the charging completes.   

Note: The actual standby time and call time depend on the operation, local network, and settings of the SIM card and mobile 

phone.  

Using battery 

The performance of the battery is affected by various factors, including wireless network settings, signal intensity, 

environment temperature, the function or settings that you select, accessories and the mode of voice, data or other applications 
that you select.   

To keep the battery in optimum performance, please follow the rules below: 

  The charging of new battery or batteries haven’t been used for long time may be longer;   
  Keep the battery in room temperature when it is being charged;   

 

It is normal that the charging time becomes longer after long time using. If the call time becomes shorter and charging time 
becomes longer after normal charging, you need to change a qualified battery. Unqualified battery may damage your phone 
and cause danger. 

 

  If the battery is left unused for too long time or the battery voltage is too low, it takes certain period of time to display the 

charging interface normally when the charger is connected.   

Note: To protect your safety and the environment, do not dispose the battery randomly.   

Warning: The short circuit of battery may cause explosion, fire or body hurt.
