Very good conversation, Pretty fast Service, wood do it again,
Have paid by Paypal, so i got the Service Manual online after 15 Min.
Very helpfully.
Greeting from Germany,
Hans
;
Good-quality scans. Detailed description. I hope I can repair the machine.

High-quality scanning. Detailed description. Recommend for all technician. A+++

This is a good quality scan of the original Service Manual from Nordmende, Germany. Contains the circuit diagram, PCB layout, adjust/tune instructions as well. It is NOT in English but in GERMAN language! That was quite right for my german friend from the lower east side in Berlin.

Received via e-mail this PDF manual is worth the money. This is a quality scan of a manual in excellent condition and is just as good as having the original manual in hand. I have later seen the original manual and it was printed in colour, but this particular manual is black & white but scan resolution is high end quality! All drawings and pictures are presented in great detail. So, nearly perfect score in my opinion.
If you own the turntable you also should own the manual!

3 PROCEDURE FOR MEASURING MICROWAVE ENERGY LEAKAGE
3.2.1. Measurement with the outer panel removed.
Whenever you replace the magnetron, measure for radiation leakage before the outer panel is installed and after all necessary components are replaced or adjusted. Special care should be taken in measuring around the magnetron.
NOTE: The U.S. Government standard is 5 mW/cm 2 while in the customer�s home. 2mW/cm 2 stated here is our own voluntary standard. (1mW/cm2 for Canada)
3.2.2.
Measurements with a fully assembled oven.
3.1.
Equipment
After all components, including outer panel are fully assembled, measure for radiation leakage around the door periphery, the door viewing window, the exhaust opening, control panel and air inlet openings.
� Electromagnatic radiation monitor � 600cc glass beaker
� Glass thermometer 212°F or 100°C
3.3.
Record keeping and notification after measurement
3.2.
Procedure for measuring radiation leakage
� After any adjustment or repair to a microwave oven, a leakage reading must be taken. Record this leakage reading on the repair ticket even if it is zero. A copy of this repair ticket and the microwave leakage reading should be kept by repair facility. � Should the radiation leakage be more than 2 mW/cm 2 (1mW/cm2 for Canada) after determining that all parts are in good condition, functioning properly, and genuine replacement parts as listed in this manual have been used, immediately notify PSTC, PSC or PCI.
Note before measuring. � Do not exceed meter full scale deflection. Leakage monitor should initially be set to the highest scale. � To prevent false readings the test probe should be held by � the grip portion of the handle only and moved along the shaded area in Figure no faster than 1 inch/sec (2.5cm/sec). � Leakage with the outer panel removed ...... less than 5mW/cm2. � Leakage for a fully assembled oven with door normally closed ...... less than 2mW/cm 2 (1mW/cm 2 for Canada). � Leakage for a fully assembled oven [Before the latch switch (primary) is interrupted] while pulling the door ...... less than 2mW/cm 2. 1. Pour 275 ± 15cc (9ozss± 1/2oz) of 20°C ± 5°C (68° ± 9°F) water in a beaker which is graduated to 600cc, and place in the center of the oven. 2. Set the radiation monitor to 2450MHz and use it following the manufacturer´s recommended test procedure to assure correct results. 3. When measuring the leakage, always use the 2 inch (5cm) spacer supplied with the probe. 4. Tap the start pad or set the timer and with the magnetron oscillating, measure the leakage by holding the probe perpendicular to the surface being measured.
