I just bought this model last week. It's very nice model with very thin profile. It wears more confortable than my G100.
However, after wearing for 1 week, there is no beep sound whenever I pressed the mode button. I had tried to set alarm but all I could see is LCD digit flashing but no alarm sound. I also looked for any "mute " function in the manual but there is none.
Is this defective? Should I send back to Casio for warranty?
