Af4 Easter Egg - Help

Hello comrades, here I decided to look for a mysterious easter eggs in Africa 4, Ted Striker was looking for this easter egg back in 2008, but then there was no DC / ED 2 and HD2 CPD from Stern (thanks for such a cool program).



I supposedly found a place to deliver these keys, but I'm worried about what I do not understand, exactly where these items should be. Maybe it will clarify what the number 3 means (highlighted in the picture)

3 is the range in meters.

Also you have to replace the first "Goto end;" with "goto ACTIVATED;" otherwise if the keys are in range the script jumps to the bottom and the "activated" label is left out.
