I didn't see any keys for that) as was the case with my FX-8000G, when I replaced the batteries in that one my heart sank when I didn't see anything when I switched it on, until I got the idea to push up the contrast. That worked. I often found that replacing the batteries left all kinds of corrupt data in the 6000/6500/7000/80000/8500G series, including barely visible contrast. On those machines at least it's always a good idea to press the Reset button on the back, and more often than not, that rectifies the poor contrast. There are only 10 types of people in this world. Those who understand binary and those who don't. |
