Before starting installation
Be careful when handling the NC-9100h. There are many delicate
electronic components that are susceptible to damage from static
electricity. To avoid such damage, use the following precautions
when handling the board.
■
Leave the NC-9100h in its anti-static bag until you are ready to
install it.
■
Make sure that you are adequately grounded before touching the
NC-9100h. Use an anti-static wrist strap and a grounding mat if
possible. If you do not have an anti-static wrist strap, touch the
bare metal surface on the back of the machine before handling
the NC-9100h.
■
Avoid moving around the work area in order to eliminate static
charge build-up.
■
If possible, do not work on a carpeted area.
■
Do not flex the board and do not touch the components on the
card.
