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

SAFETY PRECAUTIONS
NOTICE: Comply with all cautions and safety-related notes located on or inside the cabinet and on the chassis or optic unit. WARNING: Since the chassis of this receiver is connected to one side of the AC power supply during operation, whenever the receiver is plugged in service should not be attempted by anyone unfamiliar with the precautions necessary when working on this type of receiver. The following precautions should be observed: 1. Do not install, remove, or handle the optic unit in any manner unless shatterproof goggles are worn. People not so equipped should be kept away from the optic unit while handling. 2. When service is required, an isolation transformer should be inserted between power line and the receiver before any service is performed on a �HOT� chassis receiver. 3. When replacing a chassis in the receiver, all the protective devices must be put back in place, such as barriers, nonmetallic knobs, adjustment and compartment cover-shields, isolation resistors, capacitors, etc. 4. When service is required, observe the original lead dress. 5. Always use the manufacturer�s replacement components. Critical components as indicated on the circuit diagram should not be replaced by another manufacturer�s. Furthermore, where a short circuit has occurred, replace those components that indicate evidence of overheating.
Leakage Current Hot Check Plug the AC line cord directly into a 120V AC 60Hz outlet (do not use an isolated transformer for this check). Turn the AC power ON. Using a Leakage Current Tester (Simpson�s Model 228 or equivalent), measure for current from all exposed metal parts of the cabinet (antennas, screwheads, overlays, control shafts, etc.) particularly any exposed metal part having a return path to the chassis or to a known earth ground (water pipe, conduit, etc.). Any current measured must not exceed 0.5 MIU.

ALSO TEST WITH PLUG REVERSED (USING AC ADAPTER PLUS AS REQUIRED)
AC LEAKAGE TEST 6. Before returning a serviced receiver to the customer, the service technician must thoroughly test the unit to be certain that it is completely safe to operate without danger of electrical shock, and be sure that no protective device built into the receiver by the manufacturer has become defective, or inadvertently defeated during servicing. Therefore, the following checks should be performed for the continued protection of the customer and service technician. Leakage Current Cold Check With the AC plug removed from the 120V AC 60Hz source, place a jumper across the two plug prongs. Using an insulation tester (DC500V), connect one lead to the jumpered AC plug and touch the other lead to each exposed metal part (antennas, screwheads, metal overlays, control shafts, etc.), particularly any exposed metal part having a return path to the chassis should have a minimum resistor reading of 2.4M and a maximum resistor reading of 5.2M . Any resistance value below or above this range indicates an abnormality which requires corrective action. An exposed metal part having a return path to the chassis will indicate an open circuit. ANY MEASUREMENTS NOT WITHIN THE LIMITS OUTLINED ABOVE ARE INDICATIVE OF A POTENTIAL SHOCK HAZARD AND MUST BE CORRECTED BEFORE RETURNING THE RECEIVER TO THE CUSTOMER.
