Dust-free Environment
Dust is harmful for MP1800 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.
Dust requirements for the room:

Apart from dust, the router has strict requirements for SO2, H2S, NH3,
and Cl2 in the room, because these harmful gases speed up the eroding of
metals and the aging of some components.
The specific limitations are as follows:

Anti-static
MP1800 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:
z
Ensure proper equipment grounding
z
Maintain dustproof room
z
Keep suitable temperature & humidity
z
Wear anti-static equipment
z
Place the disassembled circuit board on the anti static workstation and
keep the face upturned or in the anti static bag
