This is a great site. I placed my order and by the next am it was available for download. Had some problems with some missing copy on some pages. Once I brought the error to the OMC's attention, the issue was resolved. I'll come back again.

The quality of this manual is good. It has all schematics and setup information for both the MDS-B3 and the MDS-B4. The scan quality is quite good, all pages are readable, This service manual also contains scans of the operating instructions from the User manual.

Das Service Manual war von der ersten bis zur letzten Seite sehr informativ und hilfreich. Die Darstellung aller Teile war klar und der Text gut lesbar.
Vielen Dank, das war nicht der letzte Download bei ownner-manuals.com.

Procedure : 1. Connect the oscilloscope to TP (RFACO) and TP (VC) on the CD board. 2. Insert the disc (YEDS-18). (Part No. : 3-702-101-01) 3. Press the [CD NX] button. 4. Confirm that the oscilloscope waveform is as shown in the figure below. (eye pattern) A good eye pattern means that the diamond shape (�) in the center of the waveform can be clearly distinguished. � RF signal reference waveform (eye pattern)
VOLT/DIV: 0.2 V (with the 10: 1 probe in use.) TIME/DIV: 500 ns
in phase 45° good
90° 135° 180° wrong
4. After the adjustments, apply suitable locking compound to the parts adjusted. Adjustment Location:Record/Playback/Erase Head Tape Speed Check Mode: Playback

1. Insert the WS-48B into the deck. 2. Press the N button on the deck. 3. Confirm that the frequency counter reads 3,000 ± 90 Hz. Sample value of Wow and Flutter: 0.3% or less W.RMS (JIS) (WS-48B)
CD SECTION
Note: 1. CD Block is basically constructed to operate without adjustment. 2. Use YEDS-18 disc (3-702-101-01) unless otherwise indicated. 3. Use an oscilloscope with more than 10 M� impedance. 4. Clean the object lens by an applicator with neutral detergent when the signal level is low than specified value with the following checks. 5. Check the focus bias check when optical block is replaced.
