REPLACEMENT OF BATTERY: MODULE QW-51175.
AC (ALL CLEAR)5-1.
Be sure to perform AC (All Clear) after batteries are
replaced. The memory and/or counter may be displayed
incorrectly without performing AC. Lightly touch the AC
pad of the PCB with a metal tweezer, and touch the other
tweezer with the switching plate (approx. 2 seconds).
* After performing AC, press any button to move to the
Hand Set mode. Without pressing a button, it takes
approximately 1 minute to automatically change to the
Hand Set mode.

TESTING: MODULE QW-51177.
MEASURING CURRENT CONSUMPTION7-1.
This model starts correct positioning of the second hand in the Hand Set mode immediately after AC.
When it is functioning, the value of consumption current would be a little higher as the internal circuit
operation would be different from the usual status.
Measure the current value at 5 seconds after AC is performed.
* Measure within one minute while light is blocked from the watch face.
* Supply voltage is 2.5V.
