This is the second Manual I have ordered from owner-manuals, I give it five stars because it is exactly what I expected given the age of the equipment. So the contents look a bit aged and the pictures a bit grainy, it fulfills my needs and I am glad I can still get hold of them.

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.
