DISASSEMBLY: MODULE QW-31956.
When removing the back cover, do not misplace the spring/coil.
On removing of the module from the case, please insert the precision screw driver between the module and the case pointed by arrows.
SPRING/COIL 1604-2
SPRING/COIL 2709-4 SPRING/COIL 1253-2
TESTING: MODULE QW-31957.
MEASURING CURRENT CONSUMPTION7-1.
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.
ACCURACY CHECKING7-2.
Check the accuracy of the module with the quartz timer after switching the module to [ ACCURACY
CHECKING MODE ].
The operations are shown below:
SWITCHING TO [ ACCURACY CHECKING MODE ]1)
While pressing the A button, press D and C buttons 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.
CANCELLATION OF THE [ ACCURACY CHECKING MODE ]2)
Press the D button.
Then the display is returned to its original state.
This mode will automatically return to the timekeeping mode in 1 ~ 2 hour(s) without any opera-
tion.

"Insufficient Signal" may also be the reason
for the signal receiving fault.
Insufcient Signal
The time calibration signal may not be properly received under the following conditions.
• The strength of the signal has changed due to season or time of day
• The watch is placed in the reinforced concrete building
• There is a broadcasting station nearby
• Strong enough signal cannot be received due to the position of the watch
The signal used for the local time setting differs from that for the facility testing in China using TEM cell.
* For the local time calibration signal, use the normal mode.
* To check the signal using TEM cell, perform the inspection in the Test Mode.
MANUAL/AUTO Reception7-5-1.
For details of MANUAL and AUTO reception modes, refer to the Operation Guide.
MANUAL Reception
While in Normal Time Keeping mode, hold down D for 2 seconds to start receiving signals manually.
Reception OK: The time is adjusted and “GET” appears on the display for 2 minutes.
Reception NG: No time adjustment is made and “ERR” appears on the display for 2 minutes.
* Press D to end the manual reception or the reception result display and return to the normal Time
Keeping Mode.
AUTO Reception
Turn on the AUTO Reception setting. When AUTO Reception is turned ON, the calibration signal is
automatically received up to 6 times from midnight through early morning.
(If reception is successful once, the subsequent AUTO reception will not be conducted on the same
day.)
Whether reception was successful may be conrmed with [Last Receiving Date/Time] in the [Last Reception] display.
(The date/time is updated after successful reception.)

TEST MODE7-5-2.
While on the Timekeeping mode, hold down 1)
D
and press C and B at the same time to go to the
Time Calibration Signal Test mode.
Each time 2)
D
is pressed, the test signal receiving station changes as shown below:

while in a receiving station state to start receiving a signal.
Pressing any button during reception results in a reception failure.4)
In approximately 7 minutes, check the indication and deterine the result by refering to the table 5)
