To turn off the alarm on a Casio G-Shock watch, the user must first access the "alarm mode" by selecting the button on the bottom-left. In alarm mode, select an alarm, and press the button in the top-left corner to turn it off.
In alarm mode, the button on the bottom-right is used to scroll through the list of alarms: AL1 through AL5. The alarms are only displayed when turned on and are displayed as "SNZ" when snoozed. To turn the hourly time signal on and off, select "SIG" with the scroll button, and press the button on the top-left of the watch.
