Obtain the last four digits of the lower barcode of the unit, described by the video.
In my case they were 4654.
Add 1, 2, 3 and 4 to the numbers respectively.
4 + 1 = 5
6 + 2 = 8
5 + 3 = 8
4 + 4 = 8
Only numbers 1 to 6 can be entered on the radio keypad.
So any number over 6 (7 to 10) should have 6 subtracted from it.
This will be your code.
So in my case:
4 + 1 = 5
6 + 2 = 8 - 6 = 2
5 + 3 = 8 - 6 = 2
4 + 4 = 8 - 6 = 2
Code: 5222
If you are unable to enter the code, carry out the following:
1. Turn key to the first position. The screen should show " ---- "
2. Press and hold the radio band button (BND). The screen should change to " ===="
3. Now wait until "Code In" is diplayed. This could be some time (in my case I think it was 60 mins)
