[ 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.
