How it works
Switch 2 is used to reset the safe. Switch 8 is used to set your code (on = set, off = locked). Switches 3 to 5 are used to set the code. The push button is used to enter your code.
How to test
Set your desired code using Switches 3 to 5. Once you’ve done so, toggle Switch 8 to on then back off–the safe is now set! Turn on Switch 2, and press the push button. The seven segment display should show “L” (for locked). Next turn off Switch 2 to begin entering codes. If you enter a correct code, thw seven segment display should show “U” (for unlocked).
