Warnings

E
LECTROSTATIC
Warning!
Electrostatic discharge (ESD) can damage circuit boards, disk drives and other
components. The circuit board must only be handled at an ESD workstation. If an
approved station is not available, some measure of protection can be provided by
wearing a grounded antistatic wrist strap. Keep all plastic away from the board and
do not slide the board over any surface.
After removing the board from its protective wrapper, place the board on a
grounded, static-free surface, component side up. Use an antistatic foam pad if
available.
The board should also be protected inside a closed metallic anti-static envelope
during shipment or storage.
Note The exterior coating on some metallic antistatic bags is sufficiently conductive to
cause excessive battery drain if the bag comes in contact with the bottom-side of
the VL-EBX-37.
L B
ITHIUM ATTERY
Warning!
To prevent shorting, premature failure or damage to the lithium battery, do not
place the board on a conductive surface such as metal, black conductive foam or
the outside surface of a metalized ESD protective pouch. The lithium battery may
explode if mistreated. Do not recharge, disassemble or dispose of in fire. Dispose
of used batteries promptly and in an environmentally suitable manner.
H C
ANDLING ARE
Warning! Care must be taken when handling the board not to touch the exposed circuitry
with your fingers. Though it will not damage the circuitry, it is possible that small
amounts of oil or perspiration on the skin could have enough conductivity to cause
the contents of CMOS RAM to become corrupted through careless handling,
resulting in CMOS resetting to factory defaults.
E G
ARTH ROUND
Warning!
All mounting standoffs (eight on EBX and EPIC boards, four on PC/104 boards)
should be connected to earth ground (chassis ground). This provides proper
grounding for ESD and EMI purposes.
