6. Once you have located the bearing of the best RSSI tighten the screws that allow the radio to turn
on the horizontal axis.
7. Now have the installer slowly tilt the SU on the vertical axis (tilt bracket is required for vertical
axis adjustments). While you are continuously checking the RSSI.
8. If the RSSI gets worse have him stop and start tilting it the other direction following the same
procedure as in step 7.
9. Once you have located the proper up tilt or down tilt on the SU for the best RSSI, tighten the
screws that allow the tilt bracket to pivot on the vertical axis.
Note:
If the vertical or horizontal alignment is way off when you start with step 4 you may have to try changing
both the horizontal and vertical axis at once until you can get a signal that you can start adjusting from.
