2.FRONT PANEL FACILITIES O poweR swtrcH (powER) When this switch is set to the ON position, power is supplied to the tuner's main circuits. The unit's oower switch is geared to selecting the transformer's secondary and so even at the STAND-BY position. the unit's circuitry will work as long as the power cord is connected to the power outlet. Disconnect the power cord from the AC power outlet when the unit is not in regular use. @ rurueo tNDlcAToR (TUNED) This indicates that an FM broadcast station is being receiv- ed. The indicator does not light during MW or LW reception. @ stcNAL tNDtcAToR (stcNAL 1.,31 This indicates the strength of the signals being transmitted by the broadcasting station (FM, MW or LW) which has been tuned in. The higher the lamp which lights, the stronger the signals picked up (and the better the reception). @ sreneo rNDtcAToR (srEREo) This lights automatically when an FM program is being broadcast in stereo. It does not light when the FM MUTING switch has been set to the OFF/MONO position. @ mu MUTTNG swtrcH (FM MUTTNG) In the released position when it is normally set, this switch suppresses the annoying interstation noise which is heard when tuning in FM broadcasting stations. lf the station signals are weak and there is a great deal of noise and distortion, depress this switch (and monaural sound reproduction results). This switch does not work with MW and LW reception. @ rulnnw/Lw rNDtcAToRs These indicate the band (FM, MW or LW) on which the signals from the broadcasting station are being received. @ rurutruc KNoB Rotate this knob to pick up the stations (FM, MW or LW). a;:-lI o FlFi o I t--l @ rurucnoN swtTcHES (FM, MW or LW) Depress the FM switch for listening to FM broadcasts. Depress the MW switch for listening to MW broadcasts. Depress the LW switch for listening to LW broadcasts. @ rneouENcY scALE This indicates the frequency of the broadcast station (FM, MW and LW). The top level figures (88ru'108) indicate the FM frequencies. The center level figures (55ru160) indicate the MW frequen- cies. The bottom level figures (150-350) indicate the LW frequen- cies. @ oureuT coRD (accessory) This is used to hook the unit up with the stereo amplifier. @ r-wpe FM ANTENNA (accessoryl This antenna is for listening to FM stations and it should be connected to the rear panel of the unit. This is a spare antenna for listening to FM stations and used until an outdoor FM antenna is erected. For the best reception. an outdoor antenna should be obtained. @ nrta ANTENNA AND ANTENNA cATcHER (accessory) This antenna is for listening to MW and LW stations and it should be connected to the rear panel of the unit. The anten- na catcher is used when fixing the antenna to a wall or other location. NO7-E: Even with the accessory T-type FM antenna and AM antenna it may be impossible to tune into some stations when the broad- cast stations are too far away or when the unit is located in a weak-signal area such as in the mountains. ln cases like this, use an external antenna. r) e) (3) (4) (5) (6 @ m tttru^lEo s'6+al 6rE+Eo I r-=-f-T-] r L ]L_::Jt ] tttl FMMl,i,No I FUN4noN I .I -t .L l:trlrl rl l3l;-* lffi#l 9
