7.1 Precautions for E3PDA
To ensure that the E3PDA does not fail, follow the following precautions during use of
the E3PDA:
Put the E3PDA and its components and accessories in the places wherechildren
cannot reach.
Keep the E3PDA dry.
Rain, moisture and liquid contain acidic materials and will
corrode the circuit board.
Do not store or use the E3PDA in dusty or dirty places.
Do not store the E3PDA in a place that is too hot. High temperature will shorten the
service life of electronic components.
Do not store the E3PDA in a place that is too cold. When the temperature inside the
E3PDA rises, moisture is generated inside the E3PDA, which may damage the circuit
board.
Do not try to disassemble the E3PDA. Otherwise, the E3PDA may bedamaged.
Do not touch the screen surface of the E3PDA by using a pen, a pencil or othersharp
articles in case the screen may be scratched.
Do not throw, beat or violently collide the E3PDA. Otherwise, the components of the
E3PDA may be damaged and the E3PDA may be faulty.
Do not use strong chemical products or strong detergent to clean the E3PDA. If the
E3PDA become dirty, clean the surface of the E3PDA by using a soft cloth soaked
with dilute glass detergent.
Please use the protective film to reduce wear as much as possible. The screen
protective film can improve the availability and durability of the screen.
Pay attention to the following during use of the battery.
The area where the E3PDA is charged must keep away from scraps, inflammables or
chemical substances.
When you charge the battery of a mobile device, the temperature on the batteryand
charger must be in the range 0
C to 40
C.
Do not use incompatible batteries or chargers, which may cause fire, explosion, leakage
or other hazards.
Do not disassemble, press, twist, pierce or cut the battery.
Do not make the battery short-circuited or contact the connecting terminal of the battery
by using metal or other conductive objects.
Do not insert other materials into the battery, contact the battery with water or other
liquid, or expose the battery in an open fire, explosive source or other sources of
danger.
Do not put or store the battery in the environment where the temperature is toohigh.
Do not put the battery in a microwave oven or a drying machine.
