The scan is clear and well readable with very few weaker spots, usually on black background with white letters, but with enough zoom those spots can be read.
Printout is clear, the manual is complete and has all pages scanned.
I would give 5 stars, except that it is not in color, and the schematic and PCB pages are scanned on multiple pages. The document is locked (except printing) so the pages can not be extracted to compose them together for printing on the large plotter
It is worth the price tag.

let's say first that i do not need to have a credit for my opinion, i am a retired sparkie and i voluteerd to fix an electronic device for a local "Youthgroup",as no diagram was present i checked the "net" and gambled on this site and paying some fee via PayPall, i was gladly surprised that the manual arrived as was stated, GOOD SHOW, and best wishes, John

I had been looking for a Manual for my CS2150 for quite a while -- in fact I had just about given up. I saw this site and decided to download the Manual. When I Received it by Email I was really pleased with what I got, with the result that My Kenwood 'Scope is now 100% repaired and working well. As an AV Serviceman, you need a good 'scope, and thanks to this site, and the Service Manual, I have been able to repair it. The Manual was a copy of the Factory Original and the copy was very clear, especially in the area of the Circuit Schematics, where You really need to be sure of what You are looking at.

I recently purchased a manual for a Samsung DLP tv to help with a trouble shooting problem I was having. Every tv repair shop wanted close to $400.00 for the fix, but after I found Owner-Manuals.com I hit pay dirt. The manual they had for me to purchase and download was a complete service manual for the exact tv I needed. It was complete with wiring diagrams, schematics, and even part numbers. If your the fix it yourself type I highly recommend trying to find any manual here before paying someone else to fix whatever problem your having.

Once again, excellent price and manual delivered in a timely manner and as advertised!
SECTION 1 SERVICING NOTES
1-1. WRITING FOCUS/TRACKING AUTO GAIN DATA
In general for the CD players that use a digital servo IC, the focus/ tracking gain is automatically adjusted each time a disc is changed. In this set, the gain in test disc (YEDS-18) has been written to a nonvolatile memory (IC803: X24C01S) on the Display Board, and therefore the gain is not readjusted even if a disc is changed. Accordingly, always write auto gain data when replacing the Servo Board, IC803 on Display Board, or optical pick-up. 1)Connect CN805 1 pin (IN/OUT SW) and 6 pin (GND) on Display Board. Under this condition, the set will operate even when the disc lid is open (or Key Board is not connected). 2)Connect TP (ADJ: CN105 3 pin) on Servo Board to GND, and TP (VC: CN108 2 Pin) to TP3 (TEI: IC105 @¶ pin) with lead wires respectively. 3)Connect an oscilloscope to TP (TE: CN108 1 pin).

1-2. AF MODE
With the TP (AFJ: CN105 2 Pin) connected to the GND on Servo Board, turn on the POWER switch, and the AF mode is activated and the following checking can be made. 1-2-1. FL tube check All tubes turn on, then if · button is pressed, the display will be as shown below. (Segment ON 1)

IF P button is pressed, the display will be as shown below. (Segment ON 2)

4)Insert the test disc (YEDS-18), turn on POWER switch, and play fifth music with · (PLAY) and AMS Keys on the Remocon. 5)Adjust RV101 so that the waveform on oscilloscope is verticolly symmetric with respect to the A [Vdc], and also its level is 1.3 ± 0.6 Vp-p.
B 0Vdc A
If STOP p is pressed, all tubes turn on again.
symmetric level: 1.3 ± 0.6 Vp-p
At this time, A/B � 100 = ± 22 (%) or less 6)The auto gain data are written when a lead wire between TP (ADJ: CN105 3 pin) and GND is removed. Note: If the POWER switch was turned on without connecting TP (ADJ) to the GND, auto gain data are not written to the memory even if a disc is inserted, but the previous data saved in the memory are used as focus/tracking data.
