20 Emissions and Immunity A Category 5 (or better) twisted pair cable must be used to connect th\ e X2 modules in order to maintain compliance with radio frequency energy emis\ sion regulations and ensure a suitably high level of immunity to electromagne\ tic disturbances. All other interface cables used with this equipment must be shielded in \ order to maintain compliance with radio frequency energy emission regulations \ and ensure a suitably high level of immunity to electromagnetic disturbances\ . The extender does not provide any extra error checking on the RS232 seri\ al port signals and so to ensure a suitably high level of immunity in electrical\ ly noisy installations, an RS232 protocol with bit error correction or a shielded\ CATx cable should be used. European EMC directive 89/336/EEC This equipment has been tested and found to comply with the limits for a class A computing device in accordance with the specifications in the European standard EN55022. These limits are designed to provide reasonable protection against harmful interference. This equipment generates, uses and can radiate radio frequency energy and if not installed and used in accordan\ ce with the instructions may cause harmful interference to radio or television r\ eception. However, there is no guarantee that harmful interference will not occur \ in a particular installation. If this equipment does cause interference to ra\ dio or television reception, which can be determined by turning the equipment o\ n and off, the user is encouraged to correct the interference with one or \ more of the following measures: (a) Reorient or relocate the receiving ante\ nna. (b) Increase the separation between the equipment and the receiver. (c) Co\ nnect the equipment to an outlet on a circuit different from that to which the\ receiver is connected. (d) Consult the supplier or an experienced radio/TV tech\ nician for help. FCC Compliance Statement (United States) This equipment generates, uses and can radiate radio frequency energy and if not installed and used properly, that is, in strict accordance wi\ th the manufacturer’s instructions, may cause interference to radio communic\ ation. It has been tested and found to comply with the limits for a class A com\ puting device in accordance with the specifications in Subpart J of part 15 of FCC rules, which are designed to provide reasonable protection against such interfe\ rence when the equipment is operated in a commercial environment. Operation of\ this equipment in a residential area may cause interference, in which case th\ e user at his own expense will be required to take whatever measures may be necess\ ary to correct the interference. Changes or modifications not expressly ap\ proved by the manufacturer could void the user’s authority to operate the equip\ ment. Canadian Department of Communications RFI statement This equipment does not exceed the class A limits for radio noise emissi\ ons from digital apparatus set out in the radio interference regulations of the C\ anadian Department of Communications. Le présent appareil numérique n’émet pas de bruits radioé\ lectriques dépassant les limites applicables aux appareils numériques de la classe A presc\ rites dans le règlement sur le brouillage radioélectriques publié par le m\ inistère des Communications du Canada.
