For charging tones, incoming messages, etc., these are all covered under the Notification Volume. You can mute this in settings.
For the out of service beep, I blame Samsung. It's the same one on all of their phones, and there's no way I've found to silence/mute it.
Thanks for the info, i havent "upgraded" to the CL14. I dont have any issues like everyone else on here. GPS works, long battery life, only issue I have had is, a couple of times I couldnt hang up a phone call. WTF? Its a computer, so whatcha expect. Have a nice day.
