SAFETY INSTRUCTIONS 1 2 3 4 5 Read Instructions ­ All the safety and operating instructions should be read before the unit is operated. [. . . ] The above statements apply ONLY to those products distributed by Yamaha Corporation of America or its subsidiaries. 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. SUPPLIED ACCESSORIES After unpacking, check that the following parts are contained. Indoor FM Antenna AM Loop 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.

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 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. Illuminates when an FM stereo broadcast with sufficient signal strength is received. Indicates the signal level of the received station. 7 MANUAL TUNING 3 2 1 2 TUNING MODE AUTO/MAN'L MONO Follow step 1 and 2 on the previous page. Note If you tune to an FM station manually, it is received in monaural mode automatically to increase the signal quality. "AUTO" goes off. 3 Tune to a desired station manually.
