I have a newer 7900B and i can not get any of the tones to work, hourly signal tone, button tones, timer tone, and alarm tones don't sound. The watch is not set to "mute" and everything else is working fine (I followed everything in the manual also). This has me stumped! Any ideas or suggestions would be appreciated. btw The watch has never been taken apart and has never been dropped or anything outside of what the watch is designed to handle.
Thanks all for your help.
