34、ct is in proper operating condition. 21. Outdoor Antenna GroundingBefore attempting to install this prod- uct, be sure the antenna or cable system is grounded so as to provide some protection against voltage surges and built-up static charges. a. Use No.10 AWG (5.3mm2) copper, No.8 AWG (8.4mm2) alum

35、inum, No.17 AWG (1.0mm2) copper-clad steel or bronze wire or larger, as ground wire. b. Secure antenna lead-in and ground wires to house with stand-off insulators spaced from 4 feet (1.22m) to 6 feet (1.83m) apart. c. Mount antenna discharge unit as close as possible to where lead-in enters house. d

36、. A driven rod may be used as the grounding electrode where other types of electrode systems do not exist. Refer to the National Electrical Code, ANSI/NFPA 70-1990for information. e. Use jumper wire not smaller than No.6 AWG 13.3mm2) copper or equivalent, when a separate antenna grounding electrode

Please read before applying power The receiver is normally shipped with the input line voltage selector switch set to

46、108-132 VAC for operation in the U.S. and Canada. If your operating voltage is different than this, please refer to FIGURE 1 below. The voltage select switch is located on the rear panel and must be set to the proper voltage range for your area. In addition, the proper mains fuse may need to be inst

47、alled. The unit may be set to operate over the following voltage ranges: 90- 110 VAC, 108-132 VAC, 180-220 VAC and 216-264 VAC. Most countries outside the U.S. and Canada use either 220 VAC or 240 VAC line voltage. Please be certain of the operating voltage before connecting to the mains source. The

48、 receiver will operate on either 50 Hz or 60 Hz line frequency. _ Note: The warranty does not cover damage as a result of improper voltage selection, or replacement of fuse with ratings other than those specified. _ Introduction 4 Setting for 108-132 VAC Fuse rating 400mA Setting for 90-110 VAC Fuse rating 400mA Setting for 180-220 VAC Fuse rating 200mA Setting for 216-264 VAC Fuse rating 200mA FIGURE 1 VOLTAGE SELECTOR SWITCH SETTINGS Antenna
