theres an old saying in the scene.
'if all else fails, read the instructions'
even though the instructions are on the ebay listing you probabaly bought it from (i read them myself)
im feeling nice today.
plug your lnb into the meter where it says 'to lnb' plug the other side all the way into your box,
start making adjustments to your dish first of all. google dish pointer, and it will tell you what the north south angle should be on the dish. align it according to the markings on the back of the dish.
now move your dish side to side (small movements) the needle wlll start going crazy and will beep when fine tuning.
Install your lnb first seeing as you already bought it, have a look on youtube for guides.
God i hate spoon feeding,
