[. . . ] These are often not evident from visual inspection nor the protection afforded by them necessarily can be obtained by using replacement components rated for voltage, wattage, etc. Replacement parts which have these special safety characteristics are identified in this Service Manual. Electrical components having such features are identified by marking with a on the schematics and on the parts list in this Service Manual. The use of a substitute replacement component which does not have the same safety characteristics as the PIONEER recommended replacement one, shown in the parts list in this Service Manual, may create shock, fire, or other hazards.

LINE : Set to this position when listening to a program from a component connected to the LINE terminals. TAPE 1/MD : For playback with a cassette deck or MD recorder connected to the TAPE 1/MD terminals. Press to turn power to the unit ON and OFF. STANDBY/ON switch/indicator This is the switch for electric power. This switch does not function unless the POWER OFF/ ON switch is set to ON. ON : When set to the ON position, power is supplied and the unit becomes operational. STANDBY : When set to the STANDBY position, the main power flow is cut and the unit is no longer fully operational. NOTE: This control does not operate when the DIRECT button is in the on position. # SPEAKERS A (ON/OFF) button/indicator Use this button to listen to the speaker system connected to the SPEAKERS A terminals. Set to this position when listening with headphones. 0 DIRECT button/indicator Use this button when you do not wish to pass the output from input terminal equipment through the various frequency adjusting circuits (BASS, TREBLE, BALANCE, LOUDNESS). The signals input through the input terminals are reproduced without passing through the various frequency adjusting circuits. This results in flat, pure sound which is a more faithful reproduction of the input source. The signal passes through the various frequency adjusting circuits. - LOUDNESS button/indicator Use when listening at low volume level. Boosts low and high frequencies to give added punch to playback even at low volume level. NOTE: This button does not operate when the DIRECT button is in the on position. 27 A-60 8. 3 REMOTE CONTROL UNIT 1 2 STANDBY / ON AMP CD TUNER TAPE 8 9 TAPE SELECT 3 4 5 6 7 2 DECK II 7 3 DECK I 1 TAPE ¡ 7 3 0 = ~ 4 DISC SELECT ¢ CD _ STATION + TUNER CD TUNER PHONO + VOLUME TAPE 1 TAPE 2 LINE STEREO AMPLIFIER REMOTE CONTROL UNIT Î 1 CD 2 AMP STANDBY/ON button STANDBY/ON button 8 TUNER 9 TAPE STANDBY/ON button STANDBY/ON button Switches CD player power STANDBY/ON.
