Well, this is a bad news for you. Just think of the damage that electrostatic discharge can do to these electronic devices; how much more the sudden fluctuation of the power lines can do or the electromagnetic interference resulting from the thunderstorm. This is why such electronic devices are strongly recommended to be unplugged when not in use or during thunderstorms and the likes. Unplug the device for several hours to allow the microprocessor to reset. Have it serviced by a qualified technician should the microprocessor doesn't reset after unplugging.

The cadence is different, but you can change all the other rings to a different tone. On a 76xx phone, press PROG and the CO button twice. Press your navigator button up (or down) until you hear the tone you like, then press enter to save.

Tones 01,04 and 05 tend to be reasonable.
