Everything in the manual was excellent except for a couple of pictures of specific areas in the unit that were a little dark. Owners Manuals re-sent the pdf file & the problem was corrected. Excellent product! George

Thanks again.

This is the original manufacturers service manual, with detailed info on the circit boards, explosion drawings of all parts in assembly order, and tuning instructions. The only thing missing is the information on the dimensions of the various drive belts. mail me if you need them. gcrossman_at_aol.com

[ 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.
