Super nice! Good to have a manual in digital format.
;
Great job supplying the manual.
Many of these products weerepretty obscure, so it was great that you had
the manual for it!
;
Great manual, would not have been able to operate my machine without it!!

excellent value & price! Includes everything you need to know about the NN-C777! I would buy this again.
;
Very satisfied! I was searching for several days, but nope; till I discovered your webside and there it was at a very reasonable price. Keep up the good work!

SAFETY CHECK-OUT
After correcting the original service problem, perform the following safety checks before releasing the set to the customer.

Check the area of your repair for unsoldered or poorly-soldered connections. Check the entire board surface for solder splashes and bridges. Check the interboard wiring to ensure that no wires are "pinched" or contact high-wattage resistors. Look for unauthorized replacement parts, particularly transistors, that were installed during a previous repair. Point them out to the customer and recommend their replacement. Look for parts which, though functioning, show obvious signs of deterioration. Point them out to the customer and recommend their replacement. Check the line cord for cracks and abrasion. Recommend the replacement of any such line cord to the customer. Check the B+ voltage to see it is at the values specified. Check the antenna terminals, metal trim, "metallized" knobs, screws, and all other exposed metal parts for AC leakage. Check leakage as described below.
LEAKAGE TEST The AC leakage from any exposed metal part to earth ground and from all exposed metal parts to any exposed metal part having a return to chassis, must not exceed 0.5mA (500 microampers). Leakage current can be measured by any one of three methods. 1. A commercial leakage tester, such as the Simpson 229 or RCA TW-540A. Follow the manufacturers' instructions to use these instruments. A battery-operated AC milliammeter. The Data Precision 245 digital multimeter is suitable for this job. Measuring the voltage drop across a resistor by means of a VOM or battery-operated AC voltmeter. The "limit" indication is 0.75V, so analog meters must have an accurate low voltage scale. The Simpson 250 and Sanwa SH-63Trd are examples of a passive VOM that is suitable. Nearly all battery operated digital multimeters that have a 2V AC range are suitable. (See Fig. A)
