DAU.
When handling circuit cards, observe the following precautions:
Note:

When setting switches on circuit cards, use a Portable Field Service Grounding Kit in order to prevent dam-
age to static-sensitive components.
For example, a 3M Model 8012 consists of a 2

If a CHARGE-GUARD wrist strap is to be used, connect the wrist strap to the frame or other ground using
the provided cable.
(2) Handling Circuit Cards
Whenever possible, do not handle circuit cards with bare hands.
Do not touch the surface or the mounted components. Touching the surface may damage the card.
Handle circuit cards with care.
