and the screw of the antenna cable holder. the antenna cable.
5. PRECAUTIONS FOR REPAIR: MODULE QW-3042
5-1. 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 main plate with the metallic tweezers.
The contact should be made for about two seconds.
For 2 seconds after the AC operation, do not make any button operations on these modules.
Metallic tweezers
Sensor cable holder
C. Insert a precision screwdriver between the module
and the case when you remove the module from
the case.

4. Removing of the antenna
A. Follow the instruction “Removing of the
module from the case”and remove the module. B. Remove the Reinforcement Plate that is fit
in the center. (Obtain a Cushion to place
around the antenna in a separated order.)
Never replace the sensor, the antenna or the PCB ass'y alone.
Because the matching of the sensor and antenna has been adjusted in the factory production line.

5-3. SOLAR CELL-PCB ASS'Y CONTACT CHECKING
Check a Solar cell and PCB ass'y are contacted correctly by contact spring, when a module is
disassembled.
1. To enter TEST mode.
1) While pressing Ebutton, press Aand C buttons at the normal timekeeping mode.
2. Check a Solar cell and PCB ass'y contact in the following order.
1) Display side up and place the watch on the desk.
2) Check the display indicates as figure 2.
3) Display side down and place the watch on the desk more than five seconds.
Or go to a dark room and place the watch more than five seconds.
4) Check the display indicates as figure 3.
If "SLR" is not appeared on the display, disassemble again the module and check the contact spring
between the Solar cell and PCB.
3. To exit from TEST mode
Press any button.
5-2. 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”
While pressing the E button, press Cand Dbuttons at the normal timekeeping mode.
B) CANCELLATION OF THE “ACCURACY CHECKING MODE”
Press any button except for C.
NOTE: The “ACCURACY CHECKING MODE” will automatically

5-4. HOW TO CHECK TILT SENSOR
1) Press E, Aand Dbuttons simultaneously in the timekeeping mode.
2) Check the display indicates as figure 4.
3) Tilt the watch towards you for 45 degrees so that the six o’clock side comes downward.
Tilt the watch in the following order for three times;
0 degree (for one second) -> 45 degrees (for one second) -> 0 degree.
4) Check the display indicates as figure 5 (for more than five times).
Figure 4 Figure 5
Tilt the watch whose LCD faces upward towards
you so that the six o’clock side comes downward
(repeat this for three times).
“TLT” appears on the LCD. “8888” appears on the LCD
(for more than two times).
