2. Remove the Tray Switch PCB from the Mechanism Top Cover Assembly
(344) by pulling back the two tabs holding it in place. Then pull the PCB up
and out of the holder. See Figure 7.
3. Remove the Mechanism Top Cover Assembly (344) from the Mechanism
Base assembly (315) by just pulling it off. Then lay it aside. The Top Cover
Assembly should contain four of the five CD Trays. The remaining CD Tray
should be laying on the Mechanism Base Assembly as shown in Figure 8.
4. Remove the CD Tray that remains on top of the Mechanism Base Assembly
(315). The CD Tray comes right out, with nothing holding it in. Now the Tray
Base Lock Lever (327) will be revealed.

right shown in Figure 11. Release the tabs in the direction of the arrows in
Figures 10 & 11. Then pull the Tray Base (329) forward until it is free from the

Tray Assembly
1. Position the Drive Rack (336) back as far as it can go on the bottom of the left
leg of the Tray Base (329). See Figure 12. The Carrier Lever (334) on the top
of the Tray Base, should be pulled all the way forward until it is held in place
by the Carrier Lock Lever (328). See figure 13.
2. While holding the Drive Rack (336) in place, insert the two Tray Base (329)
legs into the tracks of the Mechanism Base Assembly (315). Continue
pushing in until the first tooth of the Drive Rack meets the Drive Gear (303).
See Figure 14.

the Pulley Gear (302) in the clockwise direction. See Figure 14. The Tray
Base will begin to pull in. After a few turns you should be able to push the
Tray Base in the rest of the way.
4. Now with the Tray Base (329) back in the Mechanism Base Assembly (315),
place CD Tray #1 (307) on the Tray Base. Make sure the Hole (Groove) of
the CD Tray is fitted with the Tray Hook Spring (331). See Figure 15.
5. The other CD Trays numbered 2 through 5 (308 – 311) should be stacked
one on top of the other, with # 2 on the bottom and # 5 on top. Place these
Trays in the Mechanism Top Cover Assembly (344) with the Top Cover
Assembly facing right side up.
6. Place the Mechanism Top Cover Assembly (334) back on top of the
Mechanism Base Assembly (315). The Tray Switch PCB should be reinserted into its holder. Insert the seven screws and the re-assembly is
complete.
