Providing the manual works fine, quickly and without any problems for an acceptable price. After printing the service manual it took me only a short time to repair my carradio from Clarion. Thank You! Greetings from Heiko

I was searching a way to modify the original phono-in entry (for connection of vynil disc player, with RIAA equalization) to a line-in entry (for connection of modern analog entries, eg. ipod, mp3player).
This service manual gave me the correct hints.
It contains very useful infos for repairing and modifing the hi-fi, such as disassembling instructions, block diagrams, schematic diagrams, PCB prints, replacement parts list.
Very good!

Alignment Procedure
Step Remarks Press the 4 key to enter the TEST Mode 4. Connect the RF Signal SG: 1mV L615 Generator to the RF test point on the handset MAIN PCB. Make sure that (�47dBm) (Discriminator the frequency is 926.997467 MHz. No modulation Voltage) Connect the DC Voltmeter to the AF Terminal of RT603. Adjust L615 to indicate DC 0.85 V. SG: 1mV (�47dBm) 1 kHz ±8kHz Deviation SG: �6.0 dBµV (�113dBm) No modulation RT604 (RX AF Voltage) RT603 (SQ Point) Connect the RF Signal Generator to the RF test point on the handset MAIN PCB. Make sure that the frequency is 926.997467 MHz. Connect the AC Voltmeter across a 150-ohms dummy to the SP Connector. Adjust RT604 for a 113mV (-19dBV) reading on the AC Voltmeter. Press the 5 key to enter the TEST Mode 5. Make sure that the frequency of RF SG output is 926.997467 MHz. Adjust RT603 to turn to the point where the indication is just vibrated. Preset to Adjustment
