EPM-19 Hardware Reference Manual iv
Warranty Repair All parts and labor charges are covered, including return shipping
charges for UPS Ground delivery to United States addresses.
Non-warranty Repair All non-warranty repairs are subject to diagnosis and labor charges,
parts charges and return shipping fees. Specify the shipping method
you prefer and provide a purchase order number for invoicing the
repair.

Note:
Mark the RMA number clearly on the outside of the box before returning. Failure to do
so can delay the processing of your return.
RoHS Compliance
The EPM-19 is RoHS-compliant.
ABOUT ROHS
In 2003, the European Union issued Directive 2002/95/EC regarding the Restriction of the use of
certain Hazardous Substances (RoHS) in electrical and electronic equipment.
The RoHS directive requires producers of electrical and electronic equipment to reduce to
acceptable levels the presence of six environmentally sensitive substances: lead, mercury,
cadmium, hexavalent chromium, and the presence of poly-brominated biphenyls (PBB) and poly-
brominated diphenyl ethers (PBDE) flame retardants, in certain electrical and electronic products
sold in the European Union (EU) beginning July 1, 2006.
VersaLogic Corporation is committed to supporting customers with high-quality products and
services meeting the European Union’s RoHS directive.
Cautions
ELECTROSTATIC DISCHARGE
Electrostatic discharge (ESD) can damage 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 EPM-19.
LITHIUM BATTERY
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.

EPM-19 Hardware Reference Manual v
MOUNTING SUPPORT
The single board computer must be supported at all four mounting points to prevent excessive
flexing when expansion modules are attached and removed. Flex damage caused by excessive
force on an improperly mounted circuit board is not covered under the product warranty. See
page 5 for more details.
EARTH GROUND REQUIREMENT
All mounting standoffs should be connected to earth ground (chassis ground). This provides
proper grounding for EMI purposes. Figure 1 shows the locations of the board’s mounting holes.
All mounting holes identified in Figure 1 must be connected to earth ground.
