Introduction
• When it becomes absolutely necessary to remove a Board from its anti-static bag or case,
always place it on its anti-static mat in an area as free as possible from static electricity.
• Do not touch the pins of the IC's with your bare hands.
• Protect the PWB's from any external force so that they are not bent or damaged.
During inspection/replacement
• 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.
• Before unplugging connectors from the PWB's, make sure that the power cord has been
unplugged from the outlet.
• When removing a board from its conductive bag or anti-static 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.
• When touching the PWB, observe standard ESD procedures.
• Note that replacement of a PWB may call for readjustments or resetting of particular items.
7. Handling of other parts
• The magnet roller generates a strong magnetic field. Do not bring it near a watch, floppy disk,
magnetic card, or CRT tube.
