modification may void the manufacturer's warranty or standard repair policies.
The following practices minimize possible damage to ICs resulting from electrostatic discharge or improper insertion.

Keep parts in original containers until ready for use.
•
Avoid having plastic, vinyl or styrofoam in the work area.
•
Wear a properly installed anti-static wrist-strap.
•
Discharge personal static before handling devices.

Remove and insert boards with care.

When removing boards, handle only by non-conductive surfaces and never touch open-edge connectors except at a static-free workstation.*

Minimize handling of ICs.

Handle each IC by its body.
•
Do not slide ICs or boards over any surface.
•
Insert ICs with the proper orientation, and watch for bent pins on ICs.

* To make a plastic-laminated workbench anti-static, wash with a solution of Lux liquid detergent, and allow to dry without rinsing.

INSTRUCTIONS:

Note: The profile of the new part is different from the original part. If there is any concern regarding
"cosmetic appearance" if only one connector requires replacement, replace both connectors.
