COMPONENTS DESCRIPTION

LCD derive & Key input interface
Remote control sensor
Key scan start at base gose "L".
When BU5V & MSTOP (12pin) goes "H" (IC1 is active)
When CNTL (1pin) goes "H" (SW3.3V AVR : ON)
CD RF amp, Servo, DSP & DAC
Focus, tracking coil, Sled & Spindle motor driver IC
SW5V SW transistor
Auto Power Control
EQ SW transistor
System control microprocessor
Audio power amplifier
Multi AVR IC (for 5V, 8V, P-CON & P-ANT)
Control for MUTE, P-ANT & RESET muting
E-VOL. FM/AM tuner & stereo decoder
When BU5V line voltage is less than 3.5V, this IC output line is "L"
Memorized tuner adjustment data (save & load)
When the base goes "H" during BU applied (ON)
When the base goes "H" during ACC applied (ON)
When the base goes "L" (Muting : ON)
When the base goes "L" (SW5V : ON)
Control SW for IC7
Servo AVR (7.4V)
When the base goes "H" (Surge detection)
When the base goes "L" (DSI illumination : ON)
When the base goes "L" (Panel 5V : ON)
When the base goes "H" (Preout muting : ON)
When the base goes "H" (RF circuit gain is up)
When the base goes "H" (RF circuit gain is up)
