This is a binary system. If you don't know how binary works here is a simple explanation: The first digit is 1, the second is 2, the third is 4, the fourth is 8, and so on, doubling each time. Example in an eight digit system; 1 - 2 - 4 - 8 - 16 - 32 - 64 - 128 ----- If your binary code is 1 0 1 0 1 0 1 0 your number would be 85; 1 + 4 + 16 + 64 = 85 If I did anything wrong here, please tell me. Use keys 1 and 2 to select what you want to type in. The maximum number you can input is 255.
