The Casio Module 4756 watch is a radio-controlled atomic watch, which means the watch automatically receives a time calibration signal once a day from the atomic clock in Fort Collins, Colorado. Setting the watch is fairly easy using the radio signal from the atomic clock. Your Casio watch will keep current Standard Time as well as Daylight Saving Time during the summer.

Activate the watch functions by pressing any of the three buttons on the side of the watch. This turns the watch on in preparation for timekeeping.

Press the button on the lower left-hand side of the watch to turn the watch to “Timekeeping” mode.

Hold down the button on the top right-hand side of the watch for 5 seconds until the current time zone is displayed on the watch. Press the button on the top left-hand side of the watch until your correct time zone is displayed. “PT” stands for Pacific time, “MT” is mountain time, “CT” is central time, and “ET” is Eastern time.

Press the button on the top right-hand side of the watch to return to the timekeeping mode.

Perform a manual timekeeping reception if the watch does not display the correct time. Set the watch on a stable surface near a window to begin.

Press the button on the top-right hand side of the watch for 2 seconds or until “RD” flashes on the watch display.

Watch the hands on the watch move to the 12:00 position while the watch receives the time signal from the atomic clock. The hands will move to the correct time position after approximately 5 minutes. Do not move or touch the watch during this time. Once the correct time is displayed on the watch face, you can pick the watch back up and wear it.
