CAUTION
When the power to this equipment is turned on with the CD/MD Mechanical Unit disconnected, the capacitor C255(4700/
16) of the Main P.C.B. (CD/MD power supply section) is charged. Connecting the CD/MD P.C.B. in this state may cause
damage to its IC. Therefore, when installing the CD/MD Mechanical Unit, be sure to discharge the capacitor C255(4700/
16) of the Main P.C.B. before making connections. (To discharge it, short the W201 teB and GND with a
resistor(270
Ω
1W).)
