This is a top quality manual. You couldn't get better if you had the original and scanned it yourself. Best price on the net as well. Diagrams are clear and complete, text is sharp and easy to read. Granted you don't get the manual the second you click pay, but the few hours you have to wait for it to be available for download isn't a problem at all. This is a very reliable company.
Very VERY pleased with the product, and will buy others. Thanks!

In a word AWESOME.
I never expected the quality and abundant content that I got with this manual. Everything you'd ever want to know from a service perspective is found in this manual, along with... as a bonus, operating instructions on how to use the unit. WOW. Very impressed with the quality of the manual. You won't be disappointed if you're looking for the EVS900 service manual.

I thank Owen-Manuals.com for the wonderful service rendered to me, and this manual which I purchased helped me a lot in servicing my Denon System, which was lying in a dead state.
Thanks Owner-Manual.com

Excellent service manual, i didn't believe i could find it for such old product, it is very explanatory, managed to fix the disk player!!!
11. Rotate the AMS knob until the waveform of the oscilloscope moves closer to the specified value. In this adjustment, waveform varies at intervals of approx. 2%. Adjust the waveform so that the specified value is satisfied as much as possible. (Traverse Waveform)
5-12. FOCUS BIAS ADJUSTMENT
Adjusting Procedure : 1. Load a test disk (MDW-74/AU-1). 2. Rotate the AMS knob and display �CPLAY MODE� (S: 30). 3. Press the YES button and display �CPLAY MID�. 4. Press the MENU/NO button when �C = AD = � is displayed. 5. Rotate the AMS knob and display �FBIAS ADJUST� (S: 13). 6. Press the YES button and display � / a = �. The first four digits indicate the C1 error rate, the two digits after [/] indicate ADER, and the 2 digits after [a =] indicate the focus bias value. 7. Rotate the AMS knob in the clockwise direction and find the focus bias value at which the C1 error rate becomes 220 (Refer to Note 2). 8. Press the YES button and display � / b = �. 9. Rotate the AMS knob in the counterclockwise direction and find the focus bias value at which the C1 error rate becomes 220. 10. Press the YES button and display � / c = �. 11. Check that the C1 error rate is below 50 and ADER is 00. Then press the YES button. 12. If the �( )� in � ( )� is above 20, press the YES button. If below 20, press the MENU/NO button and repeat the adjustment from step 2. 13. Press the §EJECT button to remove the test disc. Note 1 : The relation between the C1 error and focus bias is as shown in the following figure. Find points a and b in the following figure using the above adjustment. The focal point position C is automatically calculated from points a and b. Note 2 : As the C1 error rate changes, perform the adjustment using the average vale.

Specification A = B
12. Press the YES button, and save the adjustment results in the non-volatile memory. (�EFB = SAV� will be displayed for a moment.) Next �EF MO ADJUS� is displayed. The disc stops rotating automatically. 13. Press the §EJECT button and remove the disc. 14. Load the check disc (MD) TDYS-1. 15. Roteto AMS knob and display �EF CD ADJUS� (S: 12). 16. Press the YES button and display �EFB = CD�. Servo is imposed automatically. 17. Rotate the AMS knob so that the waveform of the oscilloscope moves closer to the specified value. In this adjustment, waveform varies at intervals of approx. 2%. Adjust the waveform so that the specified value is satisfied as much as possible. (Traverse Waveform)

18. Press the YES button, display �EFB = SAV� for a moment and save the adjustment results in the non-volatile memory. Next �EF CD ADJUS� will be displayed. 19. Press the §EJECT button and remove the check disc (MD) TDYS-1. Note 1 : MO reading data will be erased during if a recorded disc is used in this adjustment. Note 2 : If the traverse waveform is not clear, connect the oscilloscope as shown in the following figure so that it can be seen more clearly.
