Unauthorized substitutes may result in fire, electric shock or other hazards. 17. Safety Check-Upon completion of any service or repairs to this product, ask the service technician to perform safety checks to determine that the product is in proper operating condition. 18. Outdoor Antenna Grounding-Before attempting to install this product, 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 (5.3mm 2 ) copper, No.8 AWG (8.4mm 2 ) aluminum, No.17 AWG (1.Omm 2 ) 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. A driven rod may be used as the grounding electrode where othertypes of electrode systems do not exist. Refer to the National Electrical Code, ANSI/NFPA 70-1990 for information. e. Use jumper wire not smaller than No.6 AWG 13.3mm 2 ) copper or equivalent, when a separate antenna grounding electrode is used.

Reception also includes FM broadcast (87 - 108 MHz) and Aircraft (118 -137 MHz) bands. The SATELLIT 800 MILLENNIUM offers excellent sensitivity, selectivity, dynamic range, and features that permit easy tuning of desired stations. Conveniently located front panel controls allow for rapid operator programming and ease of use. The unit can be operated from either the supplied AC ADAPTER or from six “D“ cell batteries (not supplied) for portable operation. A low battery voltage indication is displayed when that condition exists. Three electronically switched IF filters are provided. The front panel liquid crystal display provides feedback of the current status of the receiver. The seven digit frequency display provides resolution to 100 Hz accuracy in the AM broadcast, Aircraft and Shortwave bands. Resolution to 20 kHz is displayed in the FM broadcast band mode. Backlighting of the display is selectable by a front panel button. To prolong battery life with internal battery operation, the backlighting automatically turns off after a short delay following a function change or retuning of the receiver. Reception modes include Lower/Upper Sideband (LSB), (USB), and AM in the Shortwave, and AM broadcast bands. For the Shortwave and AM broadcast bands, a selectable sideband synchronous detector (SYNC) allows for enhanced reception by eliminating or reducing distortion due to fading signals. During FM broadcast use, stereo reception is available through the use of headphones. Other built-in reception aids include selectable slow or fast AGC, RF attenuator for use in strong signal handling conditions, as well as treble and bass controls. Two independent, real time clocks provide a local and alternative time selection. Also provided is a two event timer. A programmable memory area allows for 70 independent receiver set up memories. These memories do not require battery backup and are thus unaffected by power interruptions. All parameters associated with a particular memory channel are stored including the frequency, mode, bandwidth, fast or slow AGC, RF attenuator and synchronous detector. These memory channels may be accessed manually or through a time scan with each channel monitored for a 5 second period. 7 RadioFans.CNPOWER SUPPLY AC ADAPTER Keep curtains and other flammable materials out of The SATELLIT 800 MILLENNIUM receiver is supplied direct contact with the AC ADAPTER to avoid overheat with an auto-switchable AC ADAPTER to power it ing. indoors.
