Battery maintenance

1. Fully charge/discharge battery up to 4 cycles before achieving full 

capacity of a new battery.

2. Fully discharge and then fully charge the battery every two to three 

weeks for battery conditions.

3. Remove from the device and stored in a cool, dry, clean place if the 

battery will not be in use for a month or longer and recharge the 
battery after a storage period.

4. Do not short-circuit. A short-circuit may cause severe damage to the 

battery.

5. Do not drop, hit or otherwise abuse the battery as this may result in 

the exposure of the cell contents, which are corrosive.

6. Do not expose the battery to moisture or rain.
7. Keep battery away from fire or other sources of extreme heat. Do not 

incinerate. Exposure of battery to extreme heat may result in an 
explosion.

8. Do not use AC adapters other than the one provided with the Joybook.
9. Do not place the battery within reach of children.
10.Follow the local laws governing the disposal of batteries. As far as 

possible, submit used batteries to be recycled.

11.Use of improper batteries, or attempting to disassemble a battery, may 

result in explosions. Follow vendor recommendations in using 
batteries of the identical or equivalent type as replacements for worn-
out batteries.

Cleaning your Joybook

When cleaning the Joybook, follow these steps:
1. Turn off the Joybook, disconnect the AC adapter, and remove the 

battery. 

2. Use a damp cloth to wipe the outer surface of the Joybook. Do not 

apply liquid or spray cleaners directly on the Joybook.

3. Do not use cleaners containing alcohol or acetone. Instead, use 

cleaning fluids specially formulated for LCD screens.
