Handset Usage Common Sense


Answer: Battery life span depends on frequency of recharge. Recharge is not encouraged when the battery still has residual electricity for it will shorten life span of battery. Try to avoid recharging the battery when it still has half the electricity, or to stop using the battery in a sudden for a few months. Standard life span of battery is one year. After one years use, discharging every two months is helpful to prolonging battery life span. For new batteries it is not necessary to discharge every time before recharging. Over recharge or over discharge is deadly harmful to life span of batteries.



Answer: The first time to charge a brand new battery should take 12 to 14 hours. After entirely discharging and recharging twice or thrice, battery can finally reach its best performance. Do not over charge nor connect the battery to the charger for more than a week. Normal recharging time is 2-3 hours. It is not good to over charge. Users can refer to guide book for controlling recharging time.


Answer: Handset power shoud be shut off before taking out the battery, or the data saved in the handset will be destroyed.



Answer: It may not be able to recharge again due to low voltage of the battery.



Answer: Handsets should be prevented from watering, crashing, falling down and insulation of burning sun as well as from using in rainy, dusty and dirty places. By using handset appropriately, certain temperature can be generated from inside so that hydrosphere accumulated in handset can be evaporated. Preserve the label at the back of handset carefully for the information on it and related matters are very important for maintenance. Do not leave handset at a place too cold or too hot. Otherwise the life span and capacitance of the battery will be shortened. Too high or too low temperature of the battery influences battery recharging. A brand new battery can reach to the best state only after 2-3 times discharging and recharging. Please take off battery if the mobile phone is unused for long time. Please use the original antennas, parts or accessories in order to avoid destroying your handsets.



Answer: At first, clarify whether it is SIM card lock or handset lock. Handset lock includes LOCKCODE (4 numbers) and SECURITY CODE (5 or 6 numbers). MOTOROLA LOCK CODE begins with 0000 or 1234; SECURITY CODE begins with 00000 or 12345. NOKIA SECURITY CODE only begins with 12345. That of SIEMENS is particular as it is renewed each time. How to dispel lock after locking? New handsets from manufacturers are not set any password. Customers need to input handsets password if they need to use some confidential function. The password will exist after being input by customers at the first time. Handset will be locked after three times password faulty input. Customers can inquire from local exclusive service centers. Some types of handsets need to be sent to the corresponding manufacturers to dispel the lock. SIM card lock need to dispel PIN code and PUK code.



Answer: Do not fold SIM card as the metal part in SIM card should be protected carefully in particular, kept clean and avoided of dust pollution.

The card is only applied to GSM digital mobile phone permitted entering into the network, or it is possible to be destroyed. Do not leave the SIM card and the password together to avoid being embezzled.
