Warnings
ELECTROSTATIC DISCHARGE
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 product.
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.
HANDLING CARE
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 BIOS RAM to become
corrupted through careless handling, resulting in BIOS resetting to factory
defaults.
EARTH GROUND REQUIREMENT
Warning! All mounting holes (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. In portable applications, the
mounting holes should be connected to the ground reference of the system
power supply
