RXD-652/702/752/772S/852/A81/A601/A7015CIRCUIT DESCRIPTION1. Initialization1-1 Setting of initial conditionsWhile pressing the [ENTER] key, put the plug into an ACpower outlet.1-2 Initializing operation• A microcomputer is initialized for start when the ACpower is turned on when pressing the [ENTER] key. Atthat time, CD mechanism and CASSETTE mechanismare also initialized.• During the initial operation,the display shows INITIALIZEand after that it will be returned to STANDBY condition.1-3 Initial items and back up data*BACKED UP DATA1-4 Mechanism initialization1-4-1 CD mechanism• Disc unclamps(traverse down).• Rotary tray rotates(1/3 rotation).• If a mechanism error occurs, CD ERR is indicated on thedisplay.1-4-2 DECK mechanism• When initial condition becomes NG for the third time,decide the error. The error condition is displayed as XERR on the display.1-4-3 Error display• If both mechanism (CD/DECK) error occur, the display isindicated as follows. CD & X ERR2.
