If it is too dark
Try reducing the contast as follows
1.Press [2nd] key and release it
2.Press [DownArrow] and release it
3. Keep repeating the sequence until contrast is adequate.

If it is too light increase contrast
To increase contrast Do the same but press [UpArrow] instead of [DownArrow]

Hope it helps

When the number is to big it says something like 6.8E999? How do I get it to show me the full number?

You must be mistaken because your 6.8x10^(999) is out of reach of your calculator. The highest number that the calculator can handle is 9.99999999x10^100, and 10^100 will overflow thw memory.
There is no way you can display or even type in a number higher than 10^100.
If you are doing scientific calculations, you must keep in mind that most of the digits you are painfully trying to keep (for the sake of precision) are not really significant. Often, a correct order of magnitude combined with a few SIGNIFICANT digits is more than enough for any practical calculation.

When i type in 0.04x0.007 the answer doesnt come in full the zeroz before the decimal dont show up how do i make them show and get the full answer?????

Unfortunately you can't. If the magnitude of the number is too small or too large, the calculator automatically switches to scientific notation. Consider a number that has 30 zeros before it instead of the 3 in this example. How is that going to fit on the screen?

Have you tried messing around with the decimal setting and setting if to F (floating) or somethings besides 2? This should affect your inputting of numbers however. You're not hitting the percent key (%) by any chance, are you. I don't have this calculator but I'm not aware of any function that inserts a decimal point in a number that you enter (other than the percent key). The decimal setting should only affect the number of decimal points in the answer. Good luck and let us know how you make out. I'm curious.

Every time i punch in 1000 - 500 i keep getting a negative sign in front of my numbers. and the = doesnt work. please help

Calculators usually have two minuses, the regular minus sign and the change sign sometimes labeled (-) or (+/-). The latter is not meant to effect a subtraction, but to take the negative of the number you just entered. Big difference, would you say, but the syntax is different.
Ex: 15 - 7 is a subtraction with result 8
10 (-) displays -10 on the screen.
In some calculators the change sign is smaller than the regular minus, and is raised above the main line.
Hope it helps.

I am trying to set time and date on a calculator

OK, I bought one over the weekend just for chuckles. I figured it out.
On the top of the calculator there is a key that shows a little clock. Punch it once and the date 01-01-2000 or somesuch. Press it again and the time shows up..

Hold the time set key (=) down for a second until the first zero starts to flash. All you have to do is start punching in the time. When you are done press the time set key again. Voila!

Punch the key with the little clock again and the date shows up. Hold down the time set key for a second like explained above until it starts flashing. Enter the date with the key pad numbers. Done!

I couldn't figure this out either till I looked above each key (didn't notice what it said). Anyway, look real close.

Hope it works out for all and everyone finds this solution...
