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 2 ELECTRICAL ADJUSTMENTS
Notes: 1. Use transmitter with check and adjustment alreadycompleted. 2. The transmitter section adjustments should be completed before performing the headphones section adjustment. 3. On adjusting the headphones section, use the transmitter as a jig. Headphones MDR-RF830 Transmitter TMR-RF830R

Connect an digital voltmeter (AC range) and oscilloscope to the L-CH speaker outputs (both sides of MDD01). Receive signals by turning the TUNING VOL (RV302). Adjust the VOL (RV301) so that the RX board L-CH speaker outputs (both sides of MDD01) are 155mVrms. Connect an digital voltmeter (AC range) and oscilloscope to the R-CH speaker outputs (both sides of MDD02) and measure the voltages. At this time, check to make sure the level separation of L-CH and R-CH speaker outputs is more than 20dB. If the separation

1. Feed a signal to jig (transmitter) and connect a power supply to DC IN 9V jack (J404).
Receive frequency check and adjustment
1. Set the transmitter channel to CH2. 2. Set the transmitter noise filter SW to OFF . 3. Input a signal of 1kHz 316mVrms to onl y the transmitter LCH (J403). 4. Place transmitter and headphones at a distance of more than 5m apart. 5. Set the VOL (RV301) to MIN. 6. Position RX board TUNING VOL (RV302) to the center . 7. Connect a digital voltmeter (DC range) and an oscilloscope between IC301 pin @¡ and GND. 8. First check to make sure that a demodulated waveform of 1kHz (appr oximately 13mVrms) is outputted to the oscilloscope , then check to make sure the DC voltmeter reading is DC 1 to 1.2V . 9. If a demodulated waveform of 1kHz is not outputted to the oscilloscope or if the DC level is not within the range specified above, adjust the RX board L301 so that a demodulated waveform of 1kHz is outputted to the oscilloscope and while the wave-form is outputted, further fine adjust the L301 so that the DC voltmeter reading is DC1.1V. 10. When completed, make sure signals can be received when switching the transmitter channel to CH1 or CH3 by turning RX board TUNING VOL (RV302).
is less than 20dB, turn R V303 on the RX boar d so that the RCH output is minimal, then check to see if the level separation of L-CH and R-CH speaker outputs is more than 20dB. 9. Input a signal of 1kHz 316mVrms to only the transmitter R-CH (J402). 10. Adjust the VOL (RV301) so that the RX boar d R-CH speaker outputs (both sides of MDD02) are 155mVrms. 11. Connect an digital voltmeter (AC range) and oscilloscope to the L-CH speaker outputs (both sides of MDD01) and measure the voltages. 12. At this time, check to make sure the level separation of L-CH and R-CH speaker outputs is more than 20dB.
