THE CAPACITOR OF MIGHT HAVE SHORTED.
PLEASE GO TO AUTHORISED SERVICE. NO PERSONAL REPAIR IS DONE.

You need to Shortcut the battery with AC contact. AC can be found on the sides of watch movement(very tiny). You have to use pointed tweezers: one end on battery+, another on AC contact for three secs to get the watch started

I've never used one of these watches, but after looking online, I think this is how it's done:

Try using the top-left button to cycle through the settings, and use the button on the right to change them. So I'd imagine that after pressing the top-left button enough times, the indicator for the hourly beep will start to blink. At that point, press the rightmost button.

The indicator on the face of the watch should light up to indicate that the hourly chime is enabled.

Push the lower left button. The alarm time is showing.
Press the lower right button and it will cycle the hourly beep and alarm on/off.
Press the lower left button to exit when the setting are what you want.

Most of these resin-case F-series Casio sport watches use a fairly large lithium coin cell battery. Once the four screws holding the watch back are removed, you should be able to just pop off the stainless steel spring clip that holds the cell in place and pull it out, without having to remove any more screws. Be careful when replacing the clip, because it is asymmetrical and goes in only one way. Also be careful not to lose the tiny spring contact that connects the watch movement to the piezoelectric sound element glued to the watch back. If you lose the spring, the watch will still run, but the alarm won't sound anymore.

hello,if you have the little circle window on the left of your face,that will tell you if the alarm and chime are on.
to turn them off you must push and hold the lap/reset button and at the same time push the st./stop button:
1 time takes of the chime-hourly beep
2 times takes off the alarm tha you set
3x's puts the chime back and 4x's puts the alarm back on.

go to mode menu scroll it and find the alarm mode ,when you see in a display a bell it will alarm every hour but if take the bell display it will not alarm every hour..
