How to Assemble the Slider Ass'y in the
CD Mechanism
1. Mount the black lever1to the tray slider2 and assemble
them3.
2. Mount the white lever4 to the load slider5 and the open
slider6, and assemble them7.
3. Insert the gear9 to the groove of the holder8.
4. Insert the L shaped part of the load slider5 to the groove
of the holder8 and assemble them0.
5. Slide the load slider5 with lifting the edge of it rightwards.
Next insert the hook of the load slider5 and the boss of
the white lever4 to the groove of holder8. Then slide
the load slider5 to the fully leftward!.
6. Mount the tray slider 2 to the holder8 and assemble
them @.(note:Mount the tray slider2 to the wall of the
holder8)
7. Mount the slit of the center slider# to the boss of the
white lever4 and assemble them$.
How to Check the Slider Ass'y
After Assembly
Stand upright the slider ass'y before check
8. Slide the center slider# leftwards and position the right
edge of the gear9 to the right edge of center slider#.
Refer to %.
9. Position the boss of the open slider6 to the square hole
of the holder8 and slide the open slider6 fully rightwards. Mount the boss of the white lever4 assembled
with the open slider6 to the groove of the center
slider#.
Refer to ^.
10. Slide the center slider6 fully rightwards and slide the
boss of the center slider#.
Refer to &.
11. Mount the boss of the SW pcb to the slit of the holder8
and do holder* to the holder8. Then fix with screw).
Fig a: Turn the gear9 upwards and the tray
slider goes downwards smoothly. The
tray slider drops on the way.
Fig b: Turn the gear9 upwards and the open
slider goes downwards smoothly.

counterclockwise in the home position. The sliders separates and the sliders($ and ‹) moves more rightwards and the clamp mode starts after LOAD is over.
2-3 Clamp/Unclamp Function
The slider$ kicks the cross part of the gearº by load
mode. The gearª turns and moves the slider lack
gear# to LOAD by the door of the tray. Then the
slider# pushes the lever^ and T.U. ass'y moves
upwards. The clamp function starts by lifting the
T.U.ass'y.
The slider‹ moves to leftwards if the gear¡ turns clockwise in the home position. Then the open mode straits by
the sliders%,‹.

1. Initialization
1-1 Setting of initial conditions
While pressing the [ENTER] key, plug the AC power cord
into an 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. At
that time, CD mechanism, MD mechanism and CASSETTE mechanism are also initialized.
• During the initial operation, the display shows “INITIALIZE” and after that the clock blinks up on display.
• If a mechanism error occurs, “C” is indicated on the
display.
1-4-2 MD mechanism
• The MD ON code is input within 4 seconds after turned
the power port on, the MD initial code (D122H) is output.
If the MD on code is not input, the error indication is
displayed as "M" on the display.
1-4-3 CASSETTE mechanism
• If a mechanism error occurs, "X" is indicated on the display.
1-5 All RAM clear
While pressing [SET] key, plug the AC power cord into
an AC power outlet, the all RAM cleared.
