Battery has lost charging capabilities. Time to replace battery.
Since power goes through it first, it feed the device if battery is damaged

You have either put the batteries in wrong or you have lost programming, see the dealer if you are 100% sure the new batteries where not installed incorrectly. What about the spare key???

try to replace your battery. the battery size is triple A size the maintenance instruction is on your users manual ok.

browse through my tips and you will find link for all Casio watch manual downloads.

This means the battery has failed. Since you will need to take the machine to a dealer to have the battery changed, give them the backup and they can restore your programming.

If it's the same as ours (clock button top left, clear bottom left):

1. press and hold clock until the clock starts to flash
2. set time using h/m/s keys
3. press clock again

Hope it works
