Il download del Service Manual JVC HR 4100 non é stato eseguito
 ;
The Service Manual was just as expected, complete with schematics and I was able to download it in less than an hour after I ordered it. The only problem with these is that the schematics are hard to read due to the small font. I could remedy this by printing them on a larger printer.

Very fast, clear and usefull site !
Also this Service Manual are very well maked and with a very good definition !
Very fast download speed !
Recomended Seller !

The manual you sent me was excellent. It included clear, readable diagrams and a usable parts list. I would surely use your service again. Thanks

Payments were processed quickly and items were exactly as described. I will use owner-manuals.com in the future for any other manual needs.
3. After servicing, make the following leakage current checks to prevent the customer from being exposed to shock hazards. 1.2. Touch-Current Check 1. Plug the AC cord directly into the AC outlet. Do not use an isolation transformer for this check. 2. Connect a measuring network for touch currents between each exposed metallic part on the set and a good earth ground such as a water pipe, as shown in Figure 1. 3. Use Leakage Current Tester (Simpson 228 or equivalent) to measure the potential across the measuring network. 4. Check each exposed metallic part, and measure the voltage at each point. 5. Reserve the AC plug in the AC outlet and repeat each of the above measure. 6. The potential at any point (TOUGH CURRENT) expressed as voltage U1 and U2 , does not exceed the following values: For a. c.: U1 = 35 V (peak) and U2 = 0.35 V (peak); For d. c.: U1 = 1.0 V,
Note: The limit value of U2 = 0.35 V (peak) for a. c. and U1 = 1.0 V for d. c. correspond to the values 0.7 mA (peak) a. c. and 2.0 mA d. c. The limit value U1 = 35 V (peak) for a. c. correspond to the value 70 mA (peak) a. c. for frequencies greater than 100 kHz.
7. In case a measurement is out of the limits specified, there is a possibility of a shock hazard, and the equipment should be repaired and rechecked before it is returned to the customer.
