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!

I was very satisfied with the service manual I ordered and downloaded. I will definitely buy again from this seller.

Great product. Recieved it fast...exactly as advertised.
Setting A
1 July 1994
7. If the mean value is improper, select the [4-01] screen and change the flash setting step with
the value change keys (vw) on the process control OFF screen. Changing one step will change approximately 25 volts in the AID reference voltage. select the [4-03] screen again and repeat steps 4 to 7.
8. Press the Process Control ON key on the screen and be sure that all shift steps are 0. Then,
NOTE
� When the correct flash setting step is obtained, set the value of the actual VL (measured value) as
the target VL. During the flashing on the [4-03] screen, the actual VL shows the value that should be the target for the VL if the flash output is proper. This makes it easier to obtain the target VL and VD values. (You cannot know the target VD by doing the flashing 10 times on the [4-03] screen. This is because the VD is measured and corrected after flashing 20 times.)
� As VD and VL are related, the measured AID reference voltage for the black (or white) area of the
PC-1 chart may change when the flash (or grid) step setting is changed. Therefore, make the following checks and reset the value if the proper flash and grid setting steps have deviated. 1) Repeat steps 3 to 9 of the grid step setting. 2) Repeat steps 1 to 7 of the flash step setting. 3) Set the value of the actual VL (measured value) as the target VL when the correct flash setting step is obtained.
3. Target VL and VD setting The correct flash and grid setting steps have been set in the preceding procedures. In this procedure, read with the [4-01] screen what voltages of the OPC potentials are produced for the black and white patterns on the back of the original scale, and set them as the target VL and VD. After setting the targets, the machine will modify the flash and grid outputs so that the actual VL and VD match the target VL and VD.
1. Place a sheet of A3 (or larger) white paper on the exposure glass, near the original scale.
(This is to prevent change of reflectivity from the white-and-black pattern by a change of original density near the pattern.)
2. Select the [4-01] screen. 3. Press the Process Control OFF key, then press the ON key to reset all shift steps to 0. 4. Press the Start key, and press the Clear/Stop key immediately after the 18th flash. The machine stops after 20 flashes. (This is because the flash output compensation is applied just after flashing 10 times and the grid output compensation is applied just after 20 times.)
5. Read the actual VL (measured value). 6. Set the actual VL value as the target VL using the value change keys (vw) (10 volts per
step). If the actual VL is outside of the target VL adjustable range, set the closest value, and repeat steps 3 to 8 once again after doing step 8.
7. Read the actual VD (measured value). 8. Set the actual VD value as the target VD using the value change keys (vw) (10 volts per
step). If the actual VD is outside of the target VD adjustable range, set the closest value and repeat steps 3 to 8 once again.
