FCC/IC/CE STATEMENTS

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 la classe A prescrites dans le Règlement sur le brouillage radioélectrique publié par Industrie Canada.

EUROPEAN UNION DECLARATION OF CONFORMITY

This equipment complies with the requirements of the European EMC Directive 89/336/EEC.

CHAPTER 2: Introduction

2. Introduction

Switching between data lines manually can often damage the connected equipment, because this relatively slow and imprecise action can cause data-line surges and spikes large enough to damage today’s sensitive circuitry. With the Local/Remote Electronic Switches, you can eliminate this potential hazard. Their electronic switching action provides surgeless, spikeless changeovers—something a mechanical switch just can’t do.

In addition, these switches can be controlled remotely, from a convenient out-of-sight location.

The stock models available are:

SW980A	115-VAC 2-to-1 Switch
SW980AE	230-VAC 2-to-1 Switch
SW981A	115-VAC “X” (2-to-2) Switch
SW981AE	230-VAC “X” (2-to-2) Switch
SW982A	115-VAC 4-to-1 Switch
SW982AE	230-VAC 4-to-1 Switch

These Switches can also be cascaded to allow a larger number of ports to be switched.
