1.The charger is guaranteed to use the original charger; if the unofficial charger is used, on the one hand, the charging is slower, on the other hand, it will cause damage to the battery and components of the device to a certain extent. Do not use non-original charging.

2. Avoid charging while using it; charging while using it is easy to cause the device to heat up and burn. In the long run, it will cause irreversible damage to the battery and even the internal components of the device.

3, regular shutdown; frequent switching machine to the PDA loss is relatively large. It can be turned off once a week, so that the PDA can rest better. It is suitable to choose the frequency of switching once a week. Helps extend the life of your equipment.

4, the battery power should not be used up and then recharge; if the battery is in a low voltage state for a long time, excessive discharge will lead to charging and not charging, when the battery power is used to low battery alarm it should be charged (low battery 10% - 15% charge is best).

5. Do not continue charging for a long time after the battery is fully charged; the charging time is from 3% to 100% and the charging time is about 3 hours. After charging, the charging device should be unplugged.

6. Do not disassemble the PDA privately; non-professionals dismantle it privately. If the method is improper, the battery may be damaged or deformed. After the battery is damaged, it may easily swell or explode.

7. Place the environment; if the PDA is placed in a humid environment for a long time, it will shorten the service life of the electronic components, and the PDA should be placed in a dry and low-temperature environment.
