Once again owner-manual.com has saved the day for me, and come through with the manual I need. I looked other places too, and couldn't find it anywhere. Thank You owner-manual.com!!! You're the BEST!

very good quality that can be magnified several times, and it remains readable. For sure I will return next time the need for a service manual arise.

The service manual is really great - thanks to it I was able to install the laser unit and thus "save" my CD-player, which seemed to be impossible before I had the manual.

Note related to transportation and movement
Before transporting or moving this unit, carry out the following 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 difference in temperature between the previous location, when the humidity of the listening room is high, etc.

Operation to reset
The microprocessor may fall into malfunction (impossibility 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. ÷Please note that resetting the microprocessor clears the contents stored in, it returns the microprocessor to the condition 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 display. (When nothing is done, the display of this information continues.) Example: 71 . 16 . 06:14 3 Press the DISC 4 key and the 4 key at the same time. "BYE" will be shown on the display. 4 Press the ON/OFF key to go to Power OFF. 5 When Power ON is performed with the ON/OFF key, the settings become the default factory settings.
