Query: A candle that burned bright but quickly faded.

For the first year that I used my YO-520 I was very pleased. It had lots of room for telephone entries and added information, excellent backlight, useful scheduling feature, easy accessibility to features.Unfortunately after the first year and a month, it went "bellyup," losing all data. All I get now is a message reading "Data has been impaired! Press(Y) to CLEAR ALL memory." Sharp service was less than useful.
