What kind of chip are you using?

[ENCORE]

Do a "HARD RESET" on it. There's nothing wrong with the card/chip. You've hit some button or changed something that makes it do that. Just do the "hard reset" and then check it out. Oh ya, your manual will show ya Mike ;) :D

Mike,
Hard Reset: With the unit off............. press and hold pages and the power button at the same time. This does a hard reset of the unit and resets it back to the factory settings.
