1. During Transportation/Storage:
• During transportation or when in storage, new P .W. Boards must not be indiscriminately
removed from their protective conductive bags.
• Do not store or place P.W. Boards in a location exposed to direct sunlight and high tem-
perature.
• When it becomes absolutely necessary to remove a Board from its conductive bag or
case, always place it on its conductive mat in an area as free as possible from static elec-
tricity.
• Do not touch the pins of the ICs with your bare hands.
• Protect the PWBs from any external force so that they are not bent or damaged.
2. 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 P.W. Boards, make sure that the power cord has
been unplugged from the outlet.
• When removing a Board from its conductive bag or conductive 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, wear a wrist strap and connect its cord to a securely grounded
place whenever possible. If you cannot wear a wrist strap, touch a metal part to dis-
charge static electricity before touching the PWB.
• Note that replacement of a PWB may call for readjustments or resetting of particular
items.
• The magnet roller generates a strong magnetic field. Do not bring it near a watch, floppy
disk, magnetic card, or CRT tube.
