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!

Charged Section
The places where the commercial AC power is used without passing through the power supply transformer. If the places are touched, there is a risk of electric shock. In addition, the measuring equipment can be damaged if it is connected to the GND of the charged section and the GND of the non-charged section while connecting the set directly to the commercial AC power supply. Therefore, be sure to connect the set via an insulated transformer and supply the current.
High Voltage Generating Point
The places where voltage is 100 V or more besides the live parts are described above. You must not touch them, since there is risk of electric shock. The VSUS voltage remains for several minutes after the power to the unit is turned off. These places must not be touched until about 10 minutes after the power is turned off, or it is confirmed with a tester that there is no residual VSUS voltage. 1.

X CONNECTOR B Assy ............................... (�230V to 223V) Discharge the VSUS voltage, as shown below: [Method for discharging the VSUS voltage] 1. Set DRF_SW on the DIGITAL VIDEO Assy to ON (Drive OFF status). �1, �2 2. Leave the switch at that position for about 20-30 seconds. 3. If the power is on, turn it off. Then return DRF_SW to the OFF position. �3 Notes �1: You can also set the unit to "Drive OFF status" by sending the "DRF" RS232C command from the PC. �2: DRF_SW can be switched whether the power is on or off. �3: Power-down will occur if DRF_SW is set to OFF while the power is on. (See "7.1.5 POWER ON/OFF FUNCTION FOR THE LARGE-SIGNAL SYSTEM".)
