FEDERAL COMMUNICATIONS COMMISSION

AND

INDUSTRY CANADA

RADIO FREQUENCY INTERFERENCE STATEMENTS

This equipment generates, uses, and can radiate radio frequency
energy and if not installed and used properly, that is, in strict
accordance with the manufacturer’s instructions, may cause
interference to radio communication. It has been tested and found
to comply with the limits for a Class A computing device in
accordance with the specifications in Subpart J of Part 15 of FCC
rules, which are designed to provide reasonable protection against
such interference when the equipment is operated in a commercial
environment. Operation of this equipment in a residential area is
likely to cause interference, in which case the user at his own
expense will be required to take whatever measures may be
necessary to correct the interference.

Changes or modifications not expressly approved by the party
responsible for compliance could void the user’s authority to
operate the equipment.

This digital apparatus does not exceed the Class A limits for radio noise
emission from digital apparatus set out in the Radio Interference
Regulation of Industry Canada.

Le présent appareil numérique n’émet pas de bruits radioélectriques
dépassant les limites applicables aux appareils numériques de
classe A prescrites dans le Règlement sur le brouillage radioélectrique
publié par Industrie Canada.

CHAPTER 1: Specifications

Compliance — FCC Class A, DOC Class/MDC classe A

Standards — IEEE 802.3, Ethernet Ver. 1 and 2

The Repeater models all have two front-mounted ports. The types of ports on
each model determine the types of Interfaces each model supports, the types
of Cable Required, the Maximum Distance attainable, and which (if any)

User Controls, Indicators, and Connectors are on each model (see below).
