Preface
Antistatic Precautions
Electrostatic discharge (ESD) results from the buildup of static electricity and can cause computer
components to fail. Electrostatic discharge occurs when a person whose body contains a static
buildup touches a computer component. This product may contain static-sensitive devices that are
easily damaged. Proper handling, grounding and precautionary ESD measures are essential when
installing parts or cards. Keep parts and cards in antistatic packaging when not in use or during
transport. If possible, use antistatic floorpads and workbench pads.
When handling components, always use an antistatic wrist strap connected to a grounded equipment
frame or chassis. If a wrist strap is not available, periodically touch an unpainted metal surface on
the equipment. Never use a conductive tool, like a screwdriver or a paper clip, to set switches.
FCC Part 68 Compliance
Connection of data communications equipment to the public telephone network is regulated by
FCC Rules and Regulations. This equipment complies with Part 68 of these regulations which
require all of the following:
All connections to the telephone network must be made using standard plugs and telephone
company provided jacks or equivalent. Connection of this equipment to party lines and coin
telephones is prohibited. A label on the component side of the unit's printed circuit board provides
the FCC Registration number for the unit. If requested, give this information to the telephone
company. To connect the product to the Public Telephone Network, you are required to give the
following information to the telephone company:

with the FCC. The telephone company may change its communication facilities, equipment,
operations and procedures where reasonably required for operation. If so, the telephone company

General DataComm. Any other repair or modification by a user voids the FCC registration and the
warranty.
