DISASSEMBLY FOR REPAIR

1. How to remove the front panel.(1) Turn the power ON and then push the open/close

key to open the tray.(2) After removed the tray cover, push the open/close

key to close the tray and then turn the powerOFF.

(3) Remove the push rivet (1) and 4 screws (2, 3).(4) The front panel can be separated by removing the

3 screws (4) located at the bottom plate of thefront panel.

2. How to remove the CD mechanism (1) Remove 4 screws (5) on the left side/right side of

chassis.(2) Remove 2 screws (6) and the cap (7) on the

rear panel.(3) Disengage the CD mechanism as FIG.2.

3. How to open the tray if not comes out.(1) From the rear side of the CD mechanism, use a

screw driver or the like to turn the friction arm fullycounterclockwise.

(2) Pull out the tray front wards by hand when thetray comes just out.

* As for details of items in the below, refer to RXD-F3service manual (B51-5091-00).(1) How to detach the tray.(2) How to attach the tray.(3) Replacing the pickup.

CIRCUIT DESCRIPTION

1. Initialization

1-1 Setting of initial conditionsWhile pressing the [ENTER] key, plug the AC cord into

the AC power outlet.

1-2 Initializing operation A microcomputer is initialized for start when the AC

power is turned on while pressing the [ENTER] key. Atthat time, CD mechanism and CASSETTE mecha-nism are also initialized.

During the initial operation, the display shows INITIAL-IZE and after that the clock blinks up on display.

CAUTION: For continued safety, replacesafety critical components only with man-ufacturer's recommended parts (refer toparts list). indicates safety critical com-ponents. For continued protection againstrisk of fire, replace only with same typeand rating fuse(s). To reduce the risk ofelectric shock, leakage-current or resis-tance measurements shall be carried out(exposed parts are acceptably insulatedfrom the supply circuit) before the appli-ance is returned to the customer.

The DC voltage is an actual reading measured with a high impedance type voltmeter with a cassette loaded at playback mode. The measurementvalue may vary depending on the measuring instruments used or on the product. Bias circuit DC voltage is measured while in the record mode.
