Special Handling and Unpacking Instruction

ESD Sensitive Device!

Electronic boards and their components are sensitive to static electricity. Therefore, care

must be taken during all handling operations and inspections of this product, in order to en-

sure product integrity at all times.

Do not handle this product out of its protective enclosure while it is not used for operational purposes unless it is oth-

erwise protected.

Whenever possible, unpack or pack this product only at EOS/ESD safe work stations. Where a safe work station is not

guaranteed, it is important for the user to be electrically discharged before touching the product with his/her hands

or tools. This is most easily done by touching a metal part of your system housing.

It is particularly important to observe standard anti-static precautions when changing piggybacks, ROM devices,

jumper settings etc. If the product contains batteries for RTC or memory backup, ensure that the product is not placed

on conductive surfaces, including anti-static plastics or sponges. They can cause short circuits and damage the bat-

teries or conductive circuits on the product.
