[. . . ] * 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. s 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 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 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. q The antenna should be at least two meters (6. 6 feet) from reinforced concrete walls or metal structures. q s Optional outdoor AM antenna In steel buildings or at a great distance from the transmitter, it may be necessary to install an outside long wire antenna. GND terminal For maximum safety and minimum interference, connect the GND terminal to a good earth ground. If multipath interference is detected, the indication decreases. 6 MEMO indicator When the MEMORY button is pressed, this indicator flashes for about 5 seconds. During this period, the displayed station can be programmed to the memory by using the A/B/C/D/E button and one of the PRESET STATIONS buttons. 7 EDIT indicator Flashes by the first press of the EDIT button when you will exchange preset stations, and lights up for a moment by the second press of the EDIT button to show that the exchange has succeeded. 6 English TUNING OPERATIONS Normally, if station signals are strong and there is no interference, quick automatic-search tuning (AUTOMATIC TUNING) is possible. However, if signals of the station you want to select are weak, you must tune to it manually (MANUAL TUNING). 1 23 AUTOMATIC TUNING MANUAL TUNING POWER 4 1 Turn the power on. 1 Turn the power on. POWER 2 Select the reception band confirming it on the display. 2 Select the reception band confirming it on the display. FM/MW/LW FM/MW/LW , or , or 3 4 TUNING MODE 3 AUTO TUNING MODE AUTO/MAN'MONO AUTO/MAN'MONO Turn "AUTO" off. 4 TUNING DOWN UP Tune to a desired station manually. TUNING DOWN UP * To continue tuning search, press and hold the button. To tune to a higher frequency, press the UP button. To tune to a lower frequency, press the DOWN button. * If the station where tuning search stops is not the desired one, press again. * If the tuning search does not stop at the desired station (because the signals of the station are weak), change to the MANUAL TUNING method. Notes If you tune to an FM station manually, it is received in monaural mode automatically to increase the signal quality. · 7 PRESET TUNING MANUAL PRESET TUNING This unit can store station frequencies selected by tuning operation. Check the contents and the number of preset stations by following the procedure of the section "To recall a preset station" on page 8. To recall a preset station Simply follow the procedure of the section "To recall a preset station" on page 8. Notes q If no station is received by the automatic preset tuning search, the search finishes after "NOTHING" flashes for about 3 seconds on the display. q 2 MEMORY You can replace a preset station by another FM, MW or LW station manually by simply following the procedure of the section "To store stations" on page 8. [. . . ] Set the button so that "AUTO" lights up on the display. Use a high quality directional FM antenna. Tighten the AM loop antenna connections and rotate it for best reception. Use the manual tuning mode. Noise from thermostats or other electrical equipment. [. . . ]
