• Use the battery only for its intended purpose. Never use any charger or battery that is damaged. Do not
short-circuit the battery. Accidental short-circuiting can occur when a metallic object such as a coin, clip
or pen causes direct connection of the positive (+) and negative (-) terminals of the battery (namely the
metal strips on the battery). This might happen, for example, when you carry a spare battery in your
pocket or purse. Short-circuiting the terminals may damage the battery or the connecting object.
To remove SIM card
• You just need to hold the edges of SIM card and slide it outwards. Other operations are the same as
those described in To insert SIM card.
2.2 Battery
Your device is powered by a rechargeable battery. The full performance of a new battery is archived only
after two or three complete charge and discharge cycles (each recharge period should be about 12 to 16
hours, but not more than 24 hours). We recommend that you recharge the battery after the battery runs
out of power and the device switched off automatically.
• To archive the full performance of the battery, we recommend you fully discharge your battery once
every month. To do this, you just need to let the phone run of power and switch off automatically.
• The battery can be charged and discharged hundreds of times, but it will eventually wear out. When the
talk and standby times are noticeably shorter than normal, replace the battery.
• In recharging, it is normal that the battery becomes heat. Your device will enable automatic protection
to control temperature changes when the battery becomes heat.
• Use only the approved batteries and accessories; otherwise, your device may be damaged.
• Be sure to switch off your device before removing the battery, otherwise, the data saved in the device
may loss and the lifetime of your device may be shortened.
• Unplug the charger from the electrical plug and the device when not in use. Do not leave a fully
charged battery connected to a charger, since overcharging may shorten its lifetime. If left unused, a
fully charged battery will loss its charge over time.
