Note related to transportation and movement

Before transporting or moving this unit, carry out the follow-

ing operations.

1. Set the POWER key to ON without loading a disc.

2. Wait a few seconds and verify that the display shown

appears.

3. Set the POWER key to OFF.

Beware of condensation

When the difference between the internal temperature of the unit

and external atmosphere is large, dew (mist) may be produced on

the internal parts of the unit. In such a case, turn the unit ON and

leave it for a few hours until the condensation has dried up.

Be especially careful in the following conditions:

When the unit is brought into a place where there is a large differ-

ence in temperature between the previous location, when the

humidity of the listening room is high, etc.

The marking is located on the rear panel and says that

the component uses laser beams that have been clas-

sified as Class 1. It means that the unit is utilizing laser

beams that are of a weaker class. There is no danger of

hazardous radiation outside the unit.

CLASS 1

LASER PRODUCT

The marking of products using lasers

(Except for some areas)

Operation to reset

The microprocessor may fall into malfunction (impossibility to oper-

ate erroneous display, etc.) when the power cord is unplugged while

power is ON or due to an external factor. In this case, execute the

following procedure to reset the microprocessor and return it to

normal condition.

÷Please note that resetting the microprocessor clears the

contents stored in, it returns the microprocessor to the condi-

tion when it left the factory.

1In

POWER ON

condition, keep the

DISC 3

key and the 44

(Skip) key pressed at the same time.

2When both keys are pressed, the region code of the unit, the

software version, etc. will be displayed on the display. (When

nothing is done, the display of this information continues.)

Example: 71 . 16 . 06:14

3Press the

DISC 4

key and the 44

4key at the same time.

"BYE" will be shown on the display.

4Press the

ON/OFF

key to go to Power OFF.

5When Power ON is performed with the

ON/OFF

key, the

settings become the default factory settings.

DISASSEMBLY FOR REPAIR

1. How to open the tray if it does not come

out. (Fig. 1)

1. Turn the gear ccw in the direction of the arrow in the

drawing through the hole on loading chassis bottom.

2. Pull out the tray frontward by hand when it comes just out.

2. How to Remove the Tray (Fig. 2)

1. Remove the front panel, front chassis, power supply and

the left mecha. frame.

2. Pull out the tray frontward (1) to match the dent of tray

(2) to the protrusions of the mecha. base (3).

3. Remove the tray upward (4).

3. How to assemble the Tray (Fig. 3,4)

1. Adjust the position of the plastic cam lifter (1) and main

gear (2) in the drawing (1so that the traverse unit will

reach the lowest position.

2. Attach the tray in the direction (3, 4) of the arrow in the

drawing.

3. Push the tray backward.
