Warning!
Caution!
Caution!
Notice:
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.
Always ground yourself to remove any static
charge before touching the single board com-
puter. Modern electronic devices are very sen-
sitive to static electric charges. As a safety
precaution, use a grounding wrist strap at all
times. Place all electronic components on a
static-dissipative surface or in a static-shielded
bag when they are not in the chassis.
The computer is provided with a battery-pow-
ered Real-time Clock circuit. There is a danger
of explosion if battery is incorrectly replaced.
Replace only with same or equivalent type rec-
ommended by the manufacturer. Discard used
batteries according to manufacturer's instruc-
tions.
Before install your PCA-6289 into a chassis,
make sure that all components on both sides of
the CPU card do not touch any metal parts,
especially the chassis wall and add-on card at
the adjacent slot.
