Quick service response. A useful and very rare service manual with all details. I recomend this service.

I ordered this manual sometime in the afternoon and I received it on my e-mail the same evening.
This is a fantastically good and properly scanned copy of the original manual. All pages are of the same scale and they overlap each other. It means that you can print the manual and easily make it as a convenient paper manual.
The content of the manual is fantastic. Alignment descriptions, PCB layouts and elementary diagrams are explicit and precise. I immediately found what I was looking for. Thanks to this manual and Owner-Manuals.com my amplifier is alive again. Many thanx indded!

The manual was well-scanned and easy to read. As an added bonus, the Operator's Manual was bundled with the Service Manual!
I'd definitely use owner-manuals.com again.

Finally, i found one website, where i can download this service manual , and fix my hifi. The service manual is very good, and easy to download and to print.

[ ACCURACY CHECKING ]
Check the frequency of the quartz oscillator (32,768 Hz) with the sensor B of the quartz timer, or switch the module to �ACCURACY CHECKING MODE�. Then check the frequency of LCD drive waveforms (32Hz) with the sensor A of a quartz timer. The operations are shown below: A) SWITCHING TO �ACCURACY CHECKING MODE� Continuously push the A , C and D buttons and at the same time. Then all the segments are displayed and the LCD drive signals are changed to the static drive signal of �32 Hz� so that you can check the accuracy with the sensor A of the quartz timer. B) CANCELLATION OF THE �ACCURACY CHECKING MODE� A Push any button. Then the display is returned to its original state. NOTE: The �ACCURACY CHECKING MODE� will automatically return to the regular mode in 1 ~ 2 hour(s) without any operation.
