10. Plug the level cage cable back
into the D-Sub connector and
tighten retaining screws.
11. Place the belt onto the level
cage pulley.
12. Place the belt onto Stepper
Motor sprocket.
13. Tension belt by sliding Motor
sprocket assembly by hand
away from level cage and
tighten the four 4/40 screws
loosened in step 2 with Loctite

14. Rotate Level Cage by hand to
the CCW and CW stop and
check belt tension. Tension on
belt should just enough to
engage drive to level cage.
(approx. 3/16” play when
pinched) If belt tension is
tighter at the CCW stop than
the CW stop or vice versa than
readjust for proper tension with
the level cage oriented where
belt tension was greatest.
15. Check and/or adjust Antenna
balance.

Select the REMOTE TILT window on the ACU and;
1. Set a bubble (or bulls-eye) level on top of the Level Cage assembly. NOTE: If the level cage
is not within 4 degrees of level fore/aft or left/right, replace the Level Cage assembly.
2. If the level cage is within 4 degrees in BOTH For/Aft and Left/Right, use the UP/DOWN
arrow keys to adjust LV (fore/aft) until the level cage is level in this axis.
3. Use the LEFT/RIGHT arrow keys to adjust CL (left/right) until the level cage is level in this
axis.
4. Once the level cage is level in both axes, wait for 30 seconds then press the ENTER key.
