This Service manual is very well scanned and its clean to read, no any anti-theft words that un-english could understand. I got my CCD600 working with this manual and it´s clear shematics :)

I was very pleased with the service provided and was surprised at how good the quality was of the manual. I thought it may be a third generation copy or so, but it is as good as the websites that charge 3 times this much. I repair some electronics for family and friends without charge, so this is perfect for me. Thank you very much.

I needed a service manual as the display on my oscilloscope was very dim. I thought I'd give owner-manuals.com a try, as they advertised a huge number of manuals. Sure enough they had one listed. I bought it hoping it would be useful... actually, I bought it hoping it would be readable! I've had manuals from online sources in the past, and been very disappointed. Not this time! An excellent manual, complete, and very readable. Using it I fixed my 'scope, and as such the manual was an investment that paid off manyfold. Do I have any complaints? One very minor one - The circuit diagrams could have been scanned at a higher resolution, as some of the details were a little difficult to make out - not impossible, just not as easy as my old eyes would like! Overall, I'm very satisfied with my manual, and I will certainly be using this company again. Well done.

I Have looked for this manual for quiet a while now, I have finally found it here. I believe this is the only place they have them in a very nice scan, pages are very clear to read, some of the pages are a bit tilted but overall it is great to have this manual available for purchase. Thanks
DIFFEROID® HEAD-WORN
CM-311A CM-311A/E
esigned for touring sound, the Crown CM-311A is a rugged head-worn microphone designed for musicians or sportscasters. It sounds like the best handheld microphones� full, clear, and distortion-free, even with the loudest singers.
CONDENSER MICROPHONE
D
The CM-311A is the latest version of the patented Differoid® technology. Its cardioid pickup pattern rejects sounds from the rear, such as floor monitors. And its noise-canceling ability rejects sounds at a distance, such as floor monitors, instruments on stage, and crowd noise. In fact, the CM-311A has outstanding gain-beforefeedback and isolation. Lightweight and comfortable, the mic�s headband and boom adjust to fit any singer. An included pop filter greatly reduces breath noise and pops. Because of the boom�s unique behind-the-ear design, it does not cover up the singer�s face.
Specifications
Transducer type: Electret condenser. Frequency response (typical): 50 Hz to 17,000 Hz (see Fig. 1). Polar pattern: Cardioid (see Fig. 2). Impedance: CM-311A, 75 ohms balanced. CM-311A/E, 6 kilohms unbalanced. Recommended load impedance: CM-311A, 1000 ohms or greater. CM-311A/E, 10 kilohms. Open-circuit sensitivity, typical, closetalking: CM-311A, 4 mV/Pa* (-48 dB re 1V/Pa), CM-311A/E, 1.25 mV/Pa (-58 dB re 1V/Pa). Power sensitivity, typical, close-talking: CM-311A: -42.5 dB re 1 mW/Pa*, CM-311A/E: -71.5 dB re 1 mW/Pa. Equivalent noise level (self noise): 26 dB SPL typical (0 dB = 0.0002 dyne/cm2), A-weighted. S/N ratio: 68 dB at 94 dB SPL. Maximum SPL: CM-311A, 148 dB SPL produces 3% THD. CM-311A/E, 140 dB SPL with 3V DC, 148 dB SPL with 9V DC. Operating voltage: CM-311A, 9V DC internal alkaline battery or 18-48V phantom power. CM-311A/E, 3�9V DC from the transmitter�s battery. Polarity: Positive pressure on diaphragm produces positive voltage on CM-311A XLR pin 2 with respect to pin 3, and on CM311A/E shield with respect to white lead. Current drain: CM-311A, 5 mA nominal. CM-311A/E, 0.27 mA nominal. Battery life: CM-311A, 110 hours. CM-311A/E, approximately equal to transmitter battery life. Output connectors: CM-311A, 3-pin pro audio (XLR type). CM-311A/E, supply your own to match your transmitter. Cables (CM-311A): 2-conductor shielded, unbalanced cable, 42 inches from headband to battery pack. Use 2-conductor shielded mic cable (not included) between XLR connector and mixer mic input. Cable (CM-311A/E): In-line with this cable is a small circuit module that equalizes the microphone signal. Cable is 42 inches long from headband to module, 12 inches from module to cable end. 2-conductor shielded unbalanced cable, unterminated. Materials: High-impact plastic mic housing, brass boom, steel wire headband, highimpact plastic and steel battery pack. Finish: Satin black. Net weight: Head-worn mic, 2.1 oz (61 g). CM-311A belt pack and battery, 6.1 oz (173g). Dimensions: Headband 5.5" diameter, adjustable. Boom approximately 7" x 3". See Figs. 3 and 4. Included accessories: Microphone carrying case, WS-6 foam pop filter, clothing clip. Optional accessories: PH-4B phantom power supply (4 channels, AC powered). PH-1A phantom power supply (1 channel, battery or AC-adapter powered). WS-14 accessory windscreen. *1 pascal = 10 dynes/cm2 = 10 microbars = 94 dB SPL.
Two models are available: CM-311A and CM-311A/E. The CM-311A is powered by a 9V battery or phantom power. It has a battery belt pack (AdaptaPack®) with a battery on/off switch, a programmable mic on/off switch, and a �Mic On� LED. The CM-311A/E has no connector; you connect it to a wireless transmitter of your choice.
How to adjust for best fit and to prevent boom bounce To get all the performance you paid for with this microphone, take the time to adjust it to fit correctly. You�ll be glad you did! For best results, the CM-311A MUST be custom fitted to one wearer�s head. This simple procedure takes only a few minutes. Please refer to Fig. 5 and locate the parts described. 1. If the microphone is for yourself, we suggest that you use a mirror to double check the fit as you make adjustments. 2. Loosen (just a little) the thumbscrew located on the outside of the foam block, part way back on the boom. This allows the boom to slide in and out, and to rotate left and right.
