Part 5:  Antenna Pointing 

Step  30: 

Scan  the  Azimuth  by  slowly  swinging  the 

antenna  from  left  to  right  and  then  stop  when  the 
Heartbeat  Tone  is  replaced  by  a  Beep  Tone 
(interrupted  tone),  confirmed  by  a  transitioning 
melody 

Step 31:

 Fix the Antenna  by tightening the 

4  locking 

nuts #7-10 

(fig. 1) on the 2 clamps holding the pole 

Step 32: 

Fine pointing Azimuth (fig. 15): 

- Rotate 

Azimuth bolt #4 

(fig. 1) in any direction until the 

audio tone drops in tone  a first time 

Reverse the direction until a continuous tone is achieved 

and  continue  in  the  same  direction  until  the  audio  tone 
drops a second time 
-  Reverse  the  direction  again  and  stop  when  a  2nd 
continuous tone is achieved 

 

Step 33: 

Fine pointing Elevation (fig. 15): 

Repeat the same procedure of Step 32 with the 

Elevation 

bolt #1

 (fig. 1) instead of the azimuth bolt 

 

Step  34: 

Fine  pointing  Azimuth  a  2nd  time  (fig.  15): 

Repeat again Step 32

 

 
Step 35: 

Lock off the 2 azimuth locking nuts 

#5

 & 

#6

 

(fig. 1) 
 

Step 36: 

Lock off the 2 elevation locking nuts 

#2

 & 

#3

 

(fig. 1) 
 
 

Step  37: 

Check  the  antenna  pointing  by  gently 

pushing and pulling at the top/bottom & left/right 
 
 

Step 38: 

Check on the modem page ‘Step 2/3 -  Dish 

Pointing’  (fig.  16)  that  the  carrier  is  locked  with  a 

green arrow

 and verify signal levels
