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!

CD Adjustment Method �Perform the adjustments after the machine enters the test mode. �Place the CD mechanism on level ground. �Equipment and tools required Measuring equipment: Oscilloscope (Use the probe of 10:1) Digital Multimeter (Use it in the DC Volt range) Jitter meter (Kikusui 6235) Test Disc: TCD-782 ATD-001 1. Focus Offset Adjustment 1) Connect a digital multimeter to the test point (FE), (VC). 2) Play back the 2nd track of TCD-782. 3) Adjust SFR501 until the digital multimeter indicates 0 ± 10 mV. 2. RF Waveform Check 1) Connect an oscilloscope to test point (RF), (VC). 2) Play back the 2nd track of TCD-782. 3) Check that the RF waveform has the maximum amplitude and the center of the wedge waveform has the clear blank.

3. Jitter Check 1) While an oscilloscope is kept connected in the same test point as in step 2. RF Waveform Check, connect the output terminal of an oscilloscope to the input terminal of the jitter meter. 2) Set the VOLT range selector of an oscilloscope to 500 mV range or lower. 3) Play back the 2nd track of TCD-782. 4) Check that the jitter meter indicates 28.0 ns or less.
