;
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!

Cautions at Service
1. General Items
1) Be careful not to have your eyes or a part of body touch with laser diode at repair because this product uses laser diode. 2) Do not disassemble Pick-up at repair. If the laser diode is bad, replace the entire Pick-up. 3) Keep away from TV or other electrical units at repair to prevent influence from surrounding units. 4) If you replace the parts during repair, be sure to unplug the power cable before replacement. 5) If you insert a disc into the drive, be sure to load it correctly. 6) Because this unit can't be used by itself, surely mount it on PC (486 DMA support) and check the operations in use of private device driver floppy diskette. Refer to Instruction manual. 7)This unit has many parts with features related to safety and especially, for essential parts, the importance is indicated on circuit diagram and part list. Be certain to use the parts with same specifications at replacing these parts.
2. Earthing cautions at handling Pick-up
- Because the laser diode in optical Pick-up is subject to get out of order due to the potential difference occurring by electricity load charged in clothes or bodies, observe the following earthing items at handling. 1) Body earthing(hand) : Be sure to wear a wrist strip with one side earthed.(Impedance : Below 104). It removes the electricity formed in body. 2) Work table earthing : Put the earthed conductive plate (Impedance : Below 104) such as copper plate on work table. 3) Cautions for clothes : Do not have any clothes touch with Pick-up because the electricity formed in clothes is destroyed easily.
