4-digit code
Example - 2 6 5 3
To enter the 1st digit, in this case "2" you press the button labelled '1' two times.
Each press of button will increase the number on screen by 1, until it gets back to the start.
So
press 1 - twice to enter 2
press 2 - six times to enter 6
press 3 - five times to enter 5
press 4 - four times to enter 4
then press select i believe.
