[. . . ] Model IMPORTANT THE WIRES IN THE MAINS LEAD ARE COLOURED IN ACCORDANCE WITH THE FOLLOWING CODE: Blue: NEUTRAL Brown: LIVE The colours of the wires in the mains lead of this apparatus may not correspond with the coloured markings identifying the terminals in your plug. Proceed as follows: the wire which is coloured BLUE must be connected to the terminal which is marked with the letter N or coloured BLACK. The wire which is coloured BROWN must be connected to the terminal which is marked with the letter L or coloured RED. Making sure that neither core is connected to the earth terminal of the three pin plug. 2. [. . . ] Be sure to read the "TROUBLESHOOTING" section of this manual for advice on common operating errors before concluding that the unit is faulty. 11. Keep this manual in a safe place for future reference. 1 CONNECTIONS Never plug in this unit and other components until all connections are completed. ANTENNA CONNECTIONS q q Each antenna should be connected to the designated terminals correctly, referring to the following figure. 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.

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. 4 ST (STEREO) indicator Lights up when an FM stereo broadcast with sufficient signal strength is received. 5 Signal-level meter Indicates the signal level of the received station. 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.

TUNING DOWN UP * To continue tuning search, press and hold the 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. The automatic preset tuning search will be performed through all FM frequencies until stations are stored up to E8. [. . . ] Because of the characteristics of FM stereo broadcasts, this is limited to cases where the transmitter is far away or the antenna input is poor. There is distortion and clear reception cannot be obtained even with a good FM antenna. These noises result from lightning, fluorescent lamps, motors, thermostats and other electrical equipment. There is multipath interference. FM The ST indicator flickers and reception is noisy. The TUNING MODE button is set to the manual tuning mode. [. . . ]
