Guides I've Contributed To
Why won't my calculator turn on?I replaced the battery but nothing appears on the screen when I press the "on" button.
Answer to: Why are the characters so faint?The screen could be the problem. Faulty wiring to the display may make the characters appear too faintly. I would recommend looking at the Screen Replacement Guide.
Answer to: Why is my battery life so short?This may be a problem with the solar panel. The solar panel supplies charge to the battery, so if it is malfunctioning then it would make sense for the battery to die quickly. You should probably refer to the Solar Panel Replacement Guide.
