PRECAUTIONS FOR REPAIR: MODULE QW-1522/1523 [ AC (ALL CLEAR) AND REMOVING OF MODULE ]
1. Perform AC (ALL CLEAR) 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 arrows.

[ 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.
