6. PRECAUTIONS FOR REPAIR: QW-1664
6-1. 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 an arrow.
6-2. ACCURACY CHECKING
Check the accuracy of the module with the quartz timer after switching the module to “ACCURACY
CHECKING MODE”.
The operations are shown below:
A) SWITCHING TO “ACCURACY CHECKING MODE”
Continuously push the A, Cand Dbuttons 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 quartz timer.
B) CANCELLATION OF THE “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. CD
