Grounding or Polarization ­ Precautions should be taken so that the grounding or polarization is not defeated. Outdoor Antenna Grounding ­ If an outside antenna is connected to this unit, be sure the antenna system is grounded so as to provide some protection against voltage surges and built-up static charges. Article 810 of the National Electrical Code, ANSI/NFPA 70, provides information with regard to proper grounding of the mast and supporting structure, grounding of the lead-in wire to an antenna discharge unit, size of grounding conductors, location of antenna discharge unit, connection to grounding electrodes, and requirements for the grounding electrode.

PART H) NEC ­ NATIONAL ELECTRICAL CODE Note to CATV system installer: This reminder is provided to call the CATV system installer's attention to Article 820-40 of the NEC that provides guidelines for proper grounding and, in particular, specifies that the cable ground shall be connected to the grounding system of the building, as close to the point of cable entry as practical. 12 13 14 15 A. B. C. D. E. We Want You Listening For A Lifetime YAMAHA and the Electronic Industries Association's Consumer Electronics Group want you to get the most out of your equipment by playing it at a safe level. One that lets the sound come through loud and clear without annoying blaring or distortion ­ and, most importantly, without affecting your sensitive hearing. Since hearing damage from loud sounds is often undetectable until it is too late, YAMAHA and the Electronic Industries Association's Consumer Electronics Group recommend you to avoid prolonged exposure from excessive volume levels. 2 CAUTION: READ THIS BEFORE OPERATING YOUR UNIT 1. This unit is a sophisticated AM/FM stereo tuner. To assure proper operation and the best possible performance, please read this manual carefully. 6. Do not use force when operating switches and other controls. 2. Choose the installation location for the unit carefully. Avoid placing it in direct sunlight or close to a source of heat. Also avoid locations subject to vibration and excessive dust, heat, cold or moisture. Keep it away from such sources of hum as transformers or motors. 7. When moving the unit, be sure to first disconnect the power plug and disconnect all wires connected from the unit to other equipment. 8. Do not attempt to clean this unit with chemical solvents, because this may damage the finish. Use a clean, dry cloth. 3. Do not open the cabinet, because this may result in damage to the unit or electrical shock. If a foreign object should get into the unit, contact your local dealer. 9. Be sure to read the "TROUBLESHOOTING" section of this manual for advice on common operating errors before concluding that the unit is faulty. 4. To prevent lightning damage, disconnect the AC power plug and disconnect the antenna cable when there is an electrical storm. 10. Keep this manual in a safe place for future reference. 5. When disconnecting the power plug from the wall outlet, always pull directly on the plug; never pull the cord itself. FCC INFORMATION (U.S.A.) 1. IMPORTANT NOTICE : DO NOT MODIFY THIS UNIT!

AM Loop Antenna Indoor FM Antenna Audio connection cord 3 CONNECTIONS ANTENNA CONNECTIONS q q Each antenna should be connected to the designated terminals correctly, referring to the following figure. Both AM and FM indoor antennas are included with this unit. In general, these antennas will probably provide sufficient signal strength. Nevertheless, a properly installed outdoor antenna will give clearer reception than an indoor one. If you experience poor reception quality, an outdoor antenna may result in improvement. Outdoor FM antenna Indoor FM antenna (included) Outdoor AM antenna AM loop antenna (included) FM ANT GND AM ANT 75 UNBAL. 75-ohm antenna adapter 300-ohm feeder 75-ohm coaxial cable 75-ohm/300-ohm antenna adapter Ground 4 Connecting the indoor FM antenna *If you connect an outdoor FM antenna to this unit, do not connect the indoor FM antenna to this unit. Connecting the AM loop antenna 2 Orient so that the best reception is obtained. 1 3 * The AM loop antenna should be placed apart from the main unit. The antenna may be hung on a wall. * The AM loop antenna should be kept connected, even if an outdoor AM antenna is connected to this unit. Optional outdoor FM antenna Consult with your dealer or authorized service center about the best method of selecting and erecting an outdoor FM antenna. The choice of the feeder cable is also important. Flat ribbonshaped twin-lead cable performs well electrically, and is cheaper and somewhat easier to handle when routing it through windows and around rooms. Coaxial cable is more expensive, does a much better job of minimizing interference, is less prone to the effects of weather and close-by metal objects, and is nearly as good a signal conductor as feeder cable, particularly for foam-type coaxial cables. Coaxial cable is somewhat more difficult to install at the point where the cable enters the building. If coaxial cable is selected, make sure the antenna is designed to be used with that type of cable. * Use a 75-ohm/300-ohm antenna adapter (not included) or a 75-ohm antenna adapter (not included) for connections. 300-ohm feeder cable 75-ohm coaxial cable 75-ohm/300-ohm antenna adapter 75-ohm coaxial cable 75-ohm antenna adapter 300-ohm feeder cable 75-ohm coaxial cable Notes for FM antenna installation q To minimize automobile ignition noise, locate the antenna as far from heavy traffic as possible. q Keep the feeder cable or coaxial cable as short as possible. Do not bundle or roll up excess cable. q The antenna should be at least two meters (6.6 feet) from reinforced concrete walls or metal structu ...
