You know the radio code is easy to work out yourself right?

THis

last 4 digits off the barcode code ontop of the unit then add 1 to the 1st, 2 to the 2nd, 3 to the 3rd and 4 to the 4th digit and keep taking 6 off the resulting numbers till you end up with all digits being 6 or less then put it in.

Ie if the last 4 is 1357 then you add 1 to the 1st, 2 to the 2nd, 3 to the 3rd and 4 to the 4th digit giving 2 5 8 11 then you remove 6 from anything over 6 making your code 2525
