How to shut off FLASH LT on g shock

"G-Shock WR20BAR" could mean hundreds of different G-Shock models. If yours is an all digital G-Shock, the answer is fairly simple. When looking at the watch face, the upper left corner button is the "ADJUST" button. Press and hold the ADJUST button for a couple of seconds. You should start to see something flash on the display. Some models will have many options to select in ADJUST mode. To scroll through them, press the MODE button, which is in the lower left corner. You set the hour, minute, seconds, month, date, and year each separately. When you are done, press the ADJUST button again and you'll be back to normal time keeping.

If you want to learn more about your G-Shock, there is something called a "MODULE" inside it that is the brains of the watch. You can find that on the back of the watch, outlined in a rectangle. Usually a 4 digit number. You can download the manual for your watch using that number, if you enter it on a CASIO website:

Press the "Adjust" button. It's usually the top-left button, slightly smaller than the rest. When you have successfully pressed the button, one of the numbers on the screen (generally the seconds) should begin to flash.

Choose which number you would like to change (hours, minutes, day, etc.) by using the "Mode" button on the bottom-right to cycle through each option on the main screen. You'll know when you have reached your target position because that number will flash.

Use the top-right button (usually labeled "Start/Stop," or sometimes "Light on/off") to change the number once you have highlighted the position you wish to change. When you have finished making the desired adjustments, press the "Adjust" button again to complete the process.

Use "Adjust" on any screen of your Casio G-Shock watch. To reach the watch's other screens, press "Mode" (bottom-right button). Most G-Shock watches have four screens total, including the main screen. On each screen, use the same process described above to make adjustments to the time (with the exception of the stopwatch screen, which does not keep time.)

When you are looking at the watch you have 2 buttons on the left side, top button being A and bottom button being C. ON the right the top button in B and the bottom one is D. If you press and hold the A button in time keeping mode the numbers will start to flash. While things are flashing, hit the D button and it should switch between 24 and 12 hour times, then hit A again to escape the time setting mode

The "mode" button is there to change the function of the + & - buttons.

If you press the mode button several times you will cycle through the various setting features of the clock.

Look for the one that sets the time zone and use the + or - buttons to select your zone.

Some experimentation may be required!

Hi there,

Just in case you didn't manage to set the time / date on your tocuh screen thermo clock, I'll try to help you from my experience (no available manual at the moment!).

1. To set the time, touch the clock icon on the upper left corner;
2. Keep touching the screen for longer than 5 seconds, on the hour area;
3. Touch the hour area until you get what you want (if you prefer the 24 hour display style, touch repeatedly until you get the right hour without the AM / PM indicator next to it);
4. Touch the clock icon again to start the clock;
5. Repeat steps 1 to 4 to set up the minutes (the hour area will be replaced by the minutes area);
6. To set the date, tocuh the calendar icon on the left hand side;
7. Keep touching the screen for longer than 5 seconds, on the year area;
8. Touch the year area until you get what you want;
9. Touch the month area until you get what you want;
10. Touch the day area until you get what you want;
11. The screen will reverse to the time display after 5 seconds if no touch.
12. The TEMP (temperature) area, if touched, is toggling between C and Fahrenheit degrees.

P.S. I don't know if it is possible to set an earlier time / date, except touching. I mean, if 2009 is on the screen and you want 2007, you'll keep touching up to 2030 and then from 1901 up to 2007.

Hope it helped.

if there is a black screen and shows chg thats mean your battery level is to low ////// so you must charge as soon a possible,,,,,,

Press & hold the adjust button until the time starts to flash.

I have a G Shock DW-004 made in 1997. I had this same problem, and I tried everything to change TO military time and back to standard time. I just read the bit to try and was about to do it. I pressed the top left button to get the time to flash, and hit the light button by accident (the one with the big G on it) and VIOLA! It changed to military time. So in my model, anyway, the G light button (under the display on the edge of the watch body) changed the time to military from standard and back again, when the time is flashing.

Good luck!
