Dust is harmful for MP1800-3 router operation. Dust causes static
absorption, which makes the poor contact of metal pieces. Static
absorption appears especially when the temperature and humidity are
lower, which affects the device life and causes communication fault.

MP1800-3 router takes lots of measures in anti-static, but when the static
exceeds a certain volume, the circuits even the whole monitor are
damaged.
For router communication, static electricity originates from external
electric field of high-pressure like electricity cables and thunders, and
internal system such as floor material and chassis structure. To prevent
the damage caused by the static, do as follows:
•
Ensure proper equipment grounding
•
Maintain dustproof room
•
Keep suitable temperature & humidity
•
Wear anti-static equipment
•
Place the disassembled circuit board on the anti static workstation
and keep the face upturned or in the anti static bag
When
viewing
or removing the disassembled circuit board, touch the edge
of circuit board and avoid touching the components on the circuit board.

The various interference sources no matter from the exterior of devices or
application systems or from the interior affect the devices through
capacitance coupling, inductance coupling, electromagnetic radiation,
public impedance (including grounding system) and lead (such as power
lines, signal lines and output lines).
Therefore, pay attention to the following:
