RoHS Compliance

The EPM-15 is RoHS-compliant.

A

BOUT 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 polybrominated biphenyls (PBB) and
polybrominated 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.

Warnings

Introduction

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 EPM-15.

ITHIUM BATTERY

L

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.

EPM-15 Reference Manual 5

Introduction

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 CMOS RAM to become corrupted through careless handling (such
as when changing the CompactFlash module), resulting in CMOS resetting to
factory defaults.

Configuration and Setup

22

You will also need a Windows (or other OS) installation CD.

Basic Setup

The following steps outline the procedure for setting up a typical development system. The EPM­15 should be handled at an ESD workstation or while wearing a grounded antistatic wrist strap.

Before you begin, unpack the EPM-15 and accessories. Verify that you received all the items you
ordered. Inspect the system visually for any damaged that may have occurred in shipping.
Contact [e-mail] immediately if any items are damaged or missing.

Gather all the peripheral devices you plan to attach to the EPM-15 and their interface and power
cables.

It is recommended that you attach standoffs to the board (see Hardware Assembly) to stabilize the
board and m
