Wow very wonderful and clear!!!! I will always trust them

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!

Great Job!!! clear and efficient as always!!
it is really nice to have peple that are doing such a good work!!!!!

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 (°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 (°C) is 25 °C or less, set to the lower value. When the ambient temperature is over 25 °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.
