During Replacement:
•
Before you unplug connectors from the circuit boards, be sure
the power cord has been unplugged from the power outlet.
•
When you remove a board from its conductive bag or case, do
not touch the pins of the ICs or the printed pattern. Place it in
position by holding only the edges of the board.
•
Before you plug connectors into the board, be sure the power
cord has been unplugged from the power outlet.
During Inspection:
•
Avoid checking the IC directly with a multimeter; use connectors
on the board.
•
Never create a closed circuit across IC pins with a metal tool.
•
When it is absolutely necessary to touch the ICs and other elec-
trical components on the board, be sure to ground your body.
