Setting the Time Using the Mode and Adjust Buttons

To adjust the time on a Casio Illuminator watch, start by locating the four buttons typically positioned around the watch face: Adjust, Mode, Light, and Search (names may vary slightly depending on the model). The process primarily involves entering the time-setting mode, selecting the element to adjust, and confirming the changes.

First, press and hold the Adjust button (usually located at the top left) for about 3 seconds until the seconds digits begin to flash. This indicates that the watch is in time-setting mode. If the seconds are flashing, pressing the Mode button (bottom left) will cycle through different time elements such as:

  • Seconds
  • Hours
  • Minutes
  • Year
  • Month
  • Day

Each press of the Mode button moves the flashing indicator to the next element to be adjusted.

To change the value of the flashing element, use the Search button (bottom right) or sometimes the Light button (top right), depending on your specific model. Each press increases the value by one. Holding the button down will rapidly advance the numbers.

Once all elements are correctly set, press the Adjust button again to exit the time-setting mode. The watch will return to normal timekeeping with the updated settings.

Adjusting for 12-hour or 24-hour Format

Casio Illuminator watches allow you to toggle between 12-hour (AM/PM) and 24-hour (military) time formats. This option is usually available within the time-setting mode.

To switch the time format:

  • Enter time-setting mode by holding the Adjust button until the seconds flash.
  • Press the Mode button repeatedly until the hour digits flash.
  • Use the Search button to toggle between the 12-hour and 24-hour formats. The 12-hour format will display “AM” or “PM” indicators, whereas the 24-hour format shows the hour in a 0-23 range.
  • Press Adjust to confirm and exit.

This feature helps users customize the watch display according to personal preference or regional standards.

Using the Stopwatch and Timer Functions

The Casio Illuminator watch also includes stopwatch and countdown timer functions, which can be accessed using the Mode button. These features are useful for timing events and activities.

Operating the Stopwatch:

  • Press the Mode button until the display shows the stopwatch screen (often indicated by “STW”).
  • Press the Search button to start and stop the stopwatch.
  • Press the Adjust button to reset the stopwatch to zero when it is stopped.

Using the Countdown Timer:

  • Press the Mode button until the timer screen appears (often indicated by “TMR”).
  • Hold the Adjust button to enter timer-setting mode.
  • Use the Mode button to switch between hours, minutes, and seconds.
  • Press the Search button to adjust each value.
  • Press Adjust to save the settings.
  • Use the Search button to start or stop the countdown.
  • Press Adjust to reset the timer.

These functions enhance the versatility of the watch beyond simple timekeeping.
