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!
I was very satisfied with the service manual I ordered and downloaded. I will definitely buy again from this seller.
6.1.3 MD Mechanism Assy Adjustment and Check
1 Temperature Check (Please perform this check soon after the power has been switched on.)
Note: When IC101 (RF-AMP) or IC104 (mechanical controller) has been exchanged or when a correction changing VD+3 has been made, be sure to correctly perform all steps up to step 7.
Step No. 1 Operation Keys and Operation Method Short circuit MECH TEST MODE during the power ON, or press the ESC key. (Service remote control unit)(Fig.1) Press the REC key. When is 80 or more at this time, the adjustment is OK (step 4 and following can be omitted). is 80 (not passed) Measure the ambient temperature T (Â°C) andcheck hat the measuring value ( ) is within the standard in regard to the microcomputer set value ( ). Note: When the indication of the measuring value ( ) is not stable, and the ambient temperature T (Â°C) is 25 Â°C or less, set to the lower value. When the ambient temperature is over 25 Â°C, set to the higher value. TEMP 80 FL Display EJECT Test mode Status Remarks

2 Laser Power Check
Step No. 1 Operation Keys and Operation Method Short circuit MECH TEST MODE during the power ON, or press the ESC key. (Service remote control unit)(Fig.1) Press the SET key (Remote control unit) Measure the laser power with an optical power meter. At this time, check that the measuring value (PLAY power) meets the standard value of the table on the right. Note: When the standard value on the right is applied, the numerical value immediately after entry into test mode 2 shall be taken as the standard.
