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!
The following is a simple adjustment method. â Simple Adjustment â
Note: Since exact adjustment cannot be performed, remember the positions of the controls before performing the adjustment. If the positions after the primary adjustment are only a little different, return the controls to the original position.
8. Connect the oscilloscope to TP (TRACKING-Y) and TP (VC) on the CD board. 9. Adjust RV704 so that the waveform is as shown in the figure below. (tracking gain adjustment)
VOLT/DIV: 1 V TIME/DIV:2 ms 0V
oscillosope (DC range) CD board TP (FOCUS-Y) TP (TRACKING-Y) TP (VC)
â¢ Incorrect Examples (fundamental wave appears)
low tracking gain VOLT/DIV: 1 V TIME/DIV: 2ms 0V
Procedure: 1. Keep the set horizontal. If the set is not horizontal, this adjustment cannot be performed 2. 3. 4. 5. due to the gravity against the 2-axis device. Connect the oscilloscope TP (FOCUS-Y) and TP (VC) on the CD board. Insert the disc (YEDS-18) in and close the lid for CD. Put the set into test mode. (See page 30.) Press the ( button. From focus searching, focus is turned ON while entering CLV drawing-in mode. Tracking and sled are turned OFF. 6. Press the ( button. [Both tracking and sled are turned ON.] 7. Adjust RV702 so that the waveform is as shown in the figure below. (Focus gain adjustment)
VOLT/DIV: 100 mV TIME/DIV:2ms 100 mV 0V
high tracking gain high fandamental wave than for low gain VOLT/DIV: 1 V TIME/DIV: 2ms
Note: VOLT/DIV: with the 10:1 probe in used.
10. Release test mode after adjustment is completed. â¢ Inconnect Examples (DC level changes more than on adjusted waveform)
low focus gain VOLT/DIV: 100 mV TIME/DIV:2ms 250 mV 0V
Adjustment Location: CD board (See page 33.)
high focus gain VOLT/DIV: 100 mV TIME/DIV:2ms 100 mV 75 mV 0V
