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!

Outstanding quality manual. This is the exact documentation I needed to service my AKAI GX-210D. This is a PERFECT COPY of the service manual for my machine. Outstanding service. Thank-you!
Sect. I1 Page 2 2) Set the RANGE and FREQUENCY controls for the desired frequency. The frequency dial scale must be multiplied by the multiplying factor indicated by the RANGE switch setting to obtain the oscillator frequency. Example: 4 (on dial scale) x . l (multiplying factor indicated by RANGE switch setting) = . 4 cycles/sec.
3) Set the FUNCTION switch for the desired output waveform.
must be connected to one of the OUTPUT terminals, and the strapped pair will then be the ground side of the output.

BALANCED OUTPUT
4) Connect the equipment under test to the OUTPUT terminals.
5) Adjust the AMPLITUDE Control for the desired output voltage. Because the frequency response is rated k0.2 db, the output amplitude may be measured at any convenient frequency and the output level will be correct (within these limits) for any other frequency. NOTES When small output voltages a r e required it may be desirable to use an external attenuator. This is because the hum and noise in the output is nearly constant with output amplitude.
Connect the two OUTPUT binding posts to the equipment being supplied. The "G" binding post may then be connected to the chassis of the equipment being driven. Under these conditions the internal impedance of the Model 202A from either OUTPUT terminal to ground is 7900 ohms in series with a 1 pf capacitor (C29). A maximum dc voltage of 400 volts may be applied between either OUTPUT terminal and the "G" terminal without damaging the 1 pf capacitor (C29). The 40 ohms internal impedance (resistive) will shunt the impedance existing between the two signal inputs of the system being driven. Under circumstances where the connection places the Model 202A in series with a path carrying current, distortion of the Model 202A output will occur if greater than 10 ma peak current is caused to flow through the Model 202A output system.

Single-Ended Output C o ~ e c t i o n s
The SYNC. OUT is a negative pulse of l e s s than 5 microseconds duration and at least 10 volts peak into a 2,500 ohm load. It occurs on one of the sine and triangular c r e s t s and a t the rise o r f a l l of t h e squarewave. It occurs a t the positive c r e s t s with respect to one of the OUTPUT terminals and at the negative c r e s t of the other. Therefore, it can be changed by 180" with respect to the output system by reversing connections to the two OUTPUT terminals, which are otherwise completely interchangeable. The SYNC. OUT terminal marked "G1' is directly connected to the chassis.
