Maybe these are silly sugestions, but.... - Vieira, Luiz C. (Brazil) - 05-27-2005

Hi, Edgard;

although it seems not to be the problem, you could try:

1) hard-reset the calculator with a clip in the RESET small hole in the back of the calculator;

2) adjust the contrast with [ON] and [-] (possibly not if the no-system menu appears fine).

Let us know if anything happend.

Success!
