CD CHANGER OPERATION DESCRIPTION
1.
9 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.

r Lcm3IUNLam MOTOR
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.

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.

First, prepare the new turntable and new special washer for
replacement. The removed turntable will be deformed by
the heat of the soldering iron, and cannot be reused.
Prepare dial-type calipers.
The attached bonding material can be dissolved by using a
60W soldering iron to heat the shaft the upper part of the
turntable for about one minute.
The turntable can then be removed from the shaft by
verycarefully applying force upward at the center of the lower
surface of the turntable.
Remove the two screws and remove the spindle motor.
Attach the special washer top the spindle motor.
Clean the spindle motor’s shaft. To clean them, use a soft
cloth soaked in isopropyl alcohol.
Apply a small amount of a mixture of the ” Three bond
2001 “and “2015F” bonding materials to the motor’s shaft.
Install the turntable as shown in the figure.
Secure the turntable by pressing gently. Be sure to wipe
away (by using a piece of cloth, or similarmaterial) any
bonding material coming out of the hole.

Insert the pick-up rail into the base chassis.
If the rack of the base chassis are missing when the pick-up
rail have been installed, first wipe the tips of the rail with
alcohol.
After the pick-up has been replaced, apply grease (FLOIL
G-4748) to the
sections.
The pick-up P.W.Board pattern’is “shorted”, as shown in
the figure, so that the new pick-up will not be susceptible to
the effects of static.
