CD CHANGER OPERATION DESCRIPTION
l This set is capable of stocking and playing up to 3 CDs.
l While playing a CD, other discs can be replaced.
In this case, press the button for the disc No. you wish to remove, and then press the OPEN/CLOSE button.
l When the “POWER” button is turned off, the power turns off after the discs are loaded in the discs trays.

2. FUNCTION
(l)OPEN/CLOSE
1. The rotation of the OPEN/CLOSE MOTOR rotates the
OPEN/CLOSE IDLER GEAR via the BELT and PULLEY,
and the RACK GEAR which is intermeshed with the OPEN/
CLOSE IDLER GEAR moves forward during “OPEN”,
backwards during “CLOSE”.
l The HOME POSITION is reached when the largest square
hole in the UP/DOWN CAM GEAR is between the
SENSORS.
2. Rotate the UP/DOWN CAM GEAR counter-clockwise (with
OPEN/CLOSE during PLAY) or clockwise (with normal
OPEN/CLOSE), raise the GEAR-BLOCK BRACKET, stop
at the selected TRAY, hold the TRAY GUIDE by means of
the OPEN/CLOSE RACK and save the other TRAY
GUIDES.
3. The OPEN/CLOSE motor start running, the OPEN/CLOSE
RACK moves forward, the TRAY LOCK LEVER is raised to
lock the TRAY, and the OPEN operation commences.

1. The rotation of the LOAD/UNLOAD MOTOR rotates the
LOAD/UNLOAD DRIVE GEAR in the clockwise direction.
2. The DRIVE GEAR and the gear portion of the TRAY
meshtogether and the TRAY movers backward.
3. The completion of TRAY movement causes the UP/DOWN
MOTOR to operate and lower the TRAY HOLDER putting
the until to chucking status.
4. The rotation of the UP/DOWN MOTOR rotates the UP/
DOWN GEAR in the counter-clockwise direction. In
connection with this, the TRAY HOLDER SLIDE moves
forward, and at the same time, the RIGHT SLIDE is moved
backwards by the SYNCHRO LEVER.
