Power is supplied at the depresed ( - ) switch position (ON) and turned off at the released (I) position (OFF). @ HEADPHoNE JAcK Connect the plug on the stereo headphones to this jack when listening to sound through headphones. @ ToNE coNTRoLs BASS : The bass is increased when this control is rotated clockwise from the center position and reduced when rotated counterclockwise. TREBLE : The treble is increased when this control is rotatd clockwise from the center position and reduced when rotated counterclockwise. @ BALANcE coNTRoL This is normally kept at its center position. lt is rotated when the volume of sound delivered through the left and right channels of the speakers or headphones differs. The right channel volume is reduced when the control is rotatd toward the LEFT from the center position while the left channel volume is reduced when it is rotated toward the RIGHT. O FuNcrtoN swtrcHEs PHONO : Press when listening to records. FM : Press when listening to FM broadcasts. AM : Press when listening to AM broadcasts. @ TAPE (ADPT) SWITcH This is depresed when using a tape deck or adaptor unit connected to the rear panel TAPE/ADAPTOR jacks. @ LOUDNESS SWITcH Depress this switch to the ON position when listening to sound at a low level of volume. This will enhance the bass and treble and give more life to the sound even at a low volume. @ voLUME coNTRoL Use this to adjust the volume of the sound delivered through the speakers or headphones. The volume is increased when this control is rotated clockwise from the minimum "0" position. @ TUNING INDIcAToR (TUNING) This lights up to indicate that an FM, AM station has been tuned in. @ srEREo tNDtcAToR (srEREo) This lights up automatically when an FM station broad- casting in stereo has been tuned in. @ SPEAKERS swrrcHEs These are used to select the speakers through which you will listen to the sound. The selected speakers are now working. A: The sound is heard from the speakers connected to the speaker A terminals on the rear panel. B: The sound is heard from the speakers connected to the speaker B terminals on the rear panel. No sound will be heard when SPEAKERS A and B switches are both released. This is the position at which the sound can be heard through the headphones. NOTE:No sund will be heard through the geakers when both the A and B switches are depressed if only one et of speakerc has been connected to either the A or B SPEAKERS terminals. @ FREoUENcY scALE This indicates the frequency of the broadcasting station (FM, AM). The top level figures (88 - 108) indicate the FM band. The bottom level figures (55 - 1601 indicate the AM band. @ TUNTNG KNoB Rotate this knob to pick up stations (FM, AM). @ PowER tNDtcAToR/DtAL potNTER r6" L;N t';K t;K -IFUNCTIONl-*'-' L FI-EI-E
