The marking of products using lasers

(For countries other than U.S.A., U.S.-Military and Canada)

The marking this product has been classified as Class 1. It

means that there is no danger of hazardous radiation outside

the product.

Operation to reset

÷ Please note that resetting the microprocessor clears the

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

dition when it left the factory.

1 In Power ON condition, keep the DISC 3 key and the 4

(Skip) key pressed at the same time.

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

the software version, etc. will be displayed on the dis-

play. (When nothing is done, the display of this informa-

tion continues.) Example: 72. 14.02:05

3 Press the DISC 4 key and the 4

4

4 key at the same time.

"BYE" will be shown on the display.

4 Press the POWER ON/OFF switch to go to Power OFF.

5 When Power ON is performed with the POWER ON/OFF

switch, the settings become the default factory settings.

The microprocessor may fall into malfunction (impos-

sibility to operate 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.

DISASSEMBLY FOR REPAIR

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

(Fig.1)

1. Remove the plastic plate.

2. Turn the gear fully CCW using a flat driver and so on in the

drawing through the hole on the loading chassis bottom.

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

2. How to remove the DVD mechanism. (Fig.2)

1. Remove connectors (

1~3 and power switch lever.

2. To separate the DVD mechanism, remove screws (

4x4

and pull it out backward.
