An excellent document to assist in the repair of my old personal tape player. It includes full circuit diagrams and physical layout drawings and full instructions on disassembly and fault finding.
Well worth the meagre price.

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,

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.
GEX-P900DAB
3) Guard interval The time 25% more than the sampling time required for processing DAB signals by FFT is called "guard interval." For multipath within the time of guard interval, errors can be corrected in most cases, regardless of the D/U ratio. Mode 1 2048 points (1 ms): Number of samples required for FFT 512 points (250 µs): Guard interval
Delayed multipath wave S1 S2 Actual DAB signal S1 S2 Direct wave (OFDM wave)
Interference between different symbols (effect of delay) Time required for FFT (1 ms)
Guard interval (250 µs)
S1
S2 Received DAB signal
Time required for FFT for every symbol
The time of guard interval depends on modes. Different time of guide interval is used for transmitting frequency, receiving speed (vehicle speed), etc.
