CD changer mechanism. 

1. When CD is at play position (Figure 2), rotate reduction gear C

clock-wise as shown in Figure 3 Until disc tray is at stock position,
then rotate further to eject the disc tray so that CD can be removed
from the tray.

2. In another case, if CD mechanism is at tray No.1 play position and

to remove CD located in tray No.3, the procedure is as follows:

If the gear up down board is located at tray No.1 position, then
rotate gear clock-wise until it at stock position. Rotate reduction
gear D clockwise (Figure 4) to move the CD mechanism to tray
No.3 position.This is confirmed by checking the gear up down
board position by the marking as indicated on the main chassis as
shown in Figure 5.
