6. PRECAUTIONS FOR REPAIR: MODULE QW-3390
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 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 arrows.
— 13 —
Page 16
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”
While pressing the D button, press A and C buttons at the normal timekeeping 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”
Press 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.
6-3. TIME CALIBRATION SIGNAL TEST MODE
1) Press B, C and D button at the same time to enter the test mode.
2) Press A button to switch from one signal source to another.
J4: Fukushima, Japan (Call Sign: JJY, Frequency: 40kHz)
J6: Fukuoka/Saga, Japan (Call Sign: JJY, Frequency: 60kHz)
U6: Fort Collins, Colorado (Call Sign: WWVB, Frequency: 60kHz)
3) Press D button to start signal reception.
