THANK YOU FOR A GOOD TRANSACTION, NICE COPY, CLEAR

Very Good! All the diagram are easy to read, and its complete.

This was an excellent source of detailed assembly information on a device which is at least 12 years old. A very lucky find, coupled with great service.
;
Excellent Service Manual and best price on the Internet. This Service Manual covers everything you could ever need including full circuit schematics, component layout diagrams, stripdown procedure and full parts list/breakdown. I needed this to carry out a modification to one of these headunits and this manual covered everything I needed. Fast delivery, processed within a few hours.

Thought I would never find a copy of the Technics SX-EN2 Service Manual until I found Owner-Manuals.com. Price was very fair and I received the download promptly. While a photocopy, it is quite readable and includes all the pertinent information and diagrams. Thank you Owner-Manuals!

[ 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.
