You probably have a switch in the wrong position or need to reset the unit.

The product manual is available here:

Yours is a fairly simple one to program, and the best instructions are in the factory manual that you can download and print, at no cost, here:

BTW, they're frequencies, not codes, and you can find a great database for your area at:

When you want to complete a problem on an adding machine, such as "7 - 3," you would not key in "7," then the subtraction sign, then "3" and then an equal sign. If you do, then you will get an answer of "-4," and you know that is not the correct answer. Again, you have to think like an accountant when you are working with your adding machine. To figure this subtraction problem on an adding machine, you would need to key in "7," the addition sign, "3" and then the subtraction sign; you would get the answer of 4. You are actually working the problem as "7 + (-3)." This would be true on most modern day machines. In order to subtract, you have to add the negative number.

You can download the manual from the manufacturer's web site at http://www.usa.canon.com/consumer/controller?act=ModelInfoAct&tabact=DownloadDetailTabAct&fcategoryid=346&modelid=15431
