The Baby G watch by Casio has a fairly complicated display. It can make it hard to figure out how to set all of the features. Luckily, once you learn how to set a Baby G watch it is pretty easy to remember for the next time. However, even if you have the manual that came with the watch, that first attempt can be a bit tricky. The most important thing to learn is which button does what.
Press the button on the bottom left until you see the time on the watch, as opposed to the data bank screen. Push the button on the bottom right to switch between standard time and military time, choosing the one you would like to use. Then push the button on the top left and wait for the seconds to start flashing (the watch will also read "set" on the face). Press the button on the bottom left again, and the seconds will automatically go to "00." Push the button on the bottom right to move forward and the button on the bottom right to move backward. Push the button on the top left again to save your changes.
Repeat step 1 three times to set the hours, date and DST (Daylight Savings Time) option. Just press the top left button until the figure you'd like to change is flashing; then proceed. There are only two settings for DST. Turn it on if you live in an area that participates in the practice, and off if you don't. The indicator on the top right of the watch's display will show whether or not it is on. (The third of the oval that is on the top will be filled in when it's on.) Once you set the date, the watch will automatically adjust for the days of the week using its internal calendar.
Input names and phone numbers into the data bank. Push the button on the top left until you see "DB" on the watch's face, indicating you are in data bank mode. Then push the button on the top right until you see a blank record. Push the button on the top left and you will see a cursor. Use the two right side buttons to choose your letters, moving up and down through the alphabet. When you get to the one you'd like to use, push the bottom left button. Type in up to eight letters, using the bottom left button to skip if the name is shorter. Then use the same method to type in the person's phone number. Push the top left button to save your record.
Use the top left button to scroll through the modes so you're familiar with everything the watch offers before you begin setting it. If you can't get a blank data record, you don't have any memory left on your watch. You need to remove some data that is already saved to enter new data.
