Follow the rules below

to avoid damage to the equipment.

Make sure hands, hair, clothing, and shoes are clean before working on the

modem assembly.

cloth. Tools will damage the fragile connector. Dirt or body sweat will

cause corrosion.

If a board is to be transported, place it in its original shipping

container. If unavailable, pack it carefully with clean packing material

that will prevent physical damage and will not cause corrosion.

Do not use masking tape labels.

Hold boards by their edges whenever you handle them.

Store and ship boards in static free bags.

Store boards in a humidity controlled environment.

Do not smoke in the area where boards are used or stored.

Do not put beverages on or near boards.

corrosion and chemical damage.

4-10. MAINTENANCE PROCEDURES

Before you start a corrective maintenance procedure, you should gather all the

items or help listed in the initial setup box for that procedure. Read the

procedure carefully and do only what each step tells you to do. Some steps are

followed by a reference. Use the reference any time you are not sure what you must

do for that step. Always do the steps in the order they are given unless the

procedure requires decision steps. When decision steps are involved, go in the

order indicated by the decision.
