NOTE: When replacing parts, make sure to handle the parts
carefully. It is necessary to use anti-static hand gloves or
a wrist strap when handling sensitive parts, such as circuit
boards or PCBA.
Make sure that somebody is around to provide help when
needed, such as when moving the whole enclosure.
Place the screws in a proper place, so they won’t be lost or
mixed up during servicing.
