Je suis audiophile belge, électronicien et créateur d'enceintes acoustiques.
J'ai apprécié la qualité des documents fournis. Ils sont très lisibles, ils peuvent être agrandis sans problème et ils sont complets. Pour moi, c'est parfait. Pour cette qualité, je suis d'accord de payer. Et le système de paiement et d'envoi est simple. Merci, continuez comme cela.

The cover page was a little scary, very dark but readable. The remainder of the document was better copy and easily readable. Why would I give 5 Stars? (1) PRICE, (2) AUTHENTICITY, It was the real deal, filled with service information, including the specific information I required. (3) PRIVACY, I didn't start to get slammed with spam. (4) EASY TRANSACTION. Painless. (5) COMPLETE, I have found several manuals here, that I could find nowhere else. (6) I will be a repeat customer!

Well done!!! I found what I need to have, indeed!
Furthermore, due to my hobby is repairing vintage equipments, I added this web site in my desk toolbar because I have in mind to search further service manuals. Thanks a lot www.owner-manuals.com !

6. PRECAUTIONS FOR REPAIR: QW-1675 6-1. AC (ALL CLEAR) AND REMOVING OF MODULE
1. Perform AC (ALL CREAR) when inserting a new battery, or else the memories and/or counters may give erratic displays. Touch the AC contact and the positive (+) side of the battery or main plate with the metallic tweezers. The contact should be made for about two seconds. 2. On removing of the module from the case, please insert the precision screw driver between the module and the case pointed by an arrow.

6-2. ACCURACY CHECKING
Check the frequency of the quartz oscillator (32,786 Hz) with the sensor B of a quartz timer, or switch the module to "ACCURACY CHECKING MODE". Then check the frequency of LCD drive waveforms (32 Hz) with the sensor A of quartz timer. The operations are shown below: A) SWITCHING TO "ACCURACY CHECKING MODE" Continuously push the A, C and D buttons at the same time at the normal time keeping mode. 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 a quartz timer. B) CANCELLATION OF "ACCURACY CHECKING MODE" 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.
