PCM-6890
All-in-One Socket 370 Celeron Single Board Computer
with LCD, Ethernet, Audio, & 4 COMs
Part no. 2007689000 1st Ed. Printed in Taiwan May 1999
Quick Installation Guide
Warning! Always completely disconnect the power cord
from your chassis whenever you work with the
hardware. Do not make connections while the
power is on. Sensitive electronic components
can be damaged by sudden power surges. Only
experienced electronics personnel should open the
PC chassis.
Caution! Always ground yourself to remove any static
charge before touching the CPU card. Modern
electronic devices are very sensitive to static
electric charges. As a safety precaution, use a
grounding wrist strap at all times. Place all
electronic components in a static-dissipative
surface or static-shielded bag when they are not
in the chassis.
