By chance I figured that the only way to switch on (and switch off) the unit is with the Backspace button! But it merely comes up with a Display containing only @ signs. Absolutely no response to keystrokes.

I tried to get a Memory Lost condition by removing batteries (left them out for about 12 hours), short-cutting the battery poles and also with the reset keystroke combination (Backspace - On). But nothing helped. Also, the machine does not switch off automatically after some time of inactivity.

Would appreciate any ideas to get it back to life ...

Check the betteries with a voltage meter or just change them for new ones.
