Anti-static
MP7500 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.
