Casio atomic watches are manufactured by the Tokyo-based Casio Computer Company, Ltd. The atomic watch uses low-frequency radio signals that receive transmissions from time stations located around the world. The stations provide the most accurate times available. Casio’s G-Shock and Wave Ceptor Combi watches are multifunctional watches that update the time for accuracy daily.
Setting Functions
There are four buttons on the edge of the case of an analog/digital Casio atomic watch. The buttons are located at 2, 4, 8 and 10 o’clock. The button in the 8 o’clock position sets the world time, alarm, date alert, time recorder, stopwatch and hand setting modes. The 2 o’clock button illuminates the display. Set your atomic watch in an area clear of large buildings or mountains to receive a strong radio signal.
Setting Time Calibration
You can set the Casio atomic watch to the city closest to where you will wear the watch. If you live in the United States, set the watch to the Ft. Collins, Colo., watch station time. Hold down the button in the 10 o’clock position until “USA” is flashing. Press the 4 o’clock button for eastern cities and 2 o’clock for western cities. For example, if you live in Las Vegas, set it to “LAX” for Los Angeles by pushing the 2 o’clock button. Press the 10 o’clock button to exit. The time re-calibrates automatically daily.
Alarm Setting
Press the button in the 8 o’clock position to access the alarm mode. Then press the 4 o’clock button to access the alarm screens that provide four alarms and one snooze alarm. Select an alarm, such as “AL1,” and then hold down the 10 o’clock button until the hour flashes. The 8 o’clock button allows you to move between the hour and minutes setting. The 4 o’clock button advances the time display and 2 o’clock reverses it. Once set, exit the alarm mode by pressing the 10 o’clock button.
Date Alert Setting
Press the button in the 8 o’clock position until you access the date alert mode on the Casio atomic watch. Select a mode such as “DA1” and then hold down the 10 o’clock button until the proper month appears. Then push the button in the 8 o’clock position to move between the month and date. Use the 4 o’clock button to advance the date and 2 o’clock to reverse the date until the proper date is illuminated. Exit by pressing the 10 o’clock button.
Stopwatch Settings
Press the button in the 8 o’clock position until you find the stopwatch that illuminates “00:00.” Press the 4 o’clock button to start elapsed time, then again to stop it. Press the button in the 10 o’clock position to clear the function.
