Setup DTV04 HD TVRO Antenna
5-4
26. Press either of the LEFT & RIGHT arrow keys to skew antenna in azimuth to bring
displayed AGC to any value above the threshold value recorded in Step 23. ___________________
□
LEFT
arrow key drives antenna CCW (decrements AZ value)
RIGHT
arrow key drives antenna CW (increments AZ value)
27. With AGC value above threshold, Press the TRACK key to enable tracking. _____________
□
28. Press the
NEXT
arrow key until ‘SAT’ window is displayed and verify decoded NID of FFFE
is displayed in the bottom right hand side of the screen. __________________________________
□
If the displayed NID is any other value then FFFE, turn tracking off, and resume azimuth sweeps until
101W is properly identified.
29. Press the
NEXT
arrow key until Antenna window is displayed. ______________________
□
30. Record On-Sat AZ and EL position values.
AZ___________ EL____________ ____________________________________________________
□
31. Using the DIRECTV satellite receiver verify signal strength on both even and odd transponders
(Refer to satellite receiver manual for instructions). _______________________________________
□
32. Calculate the required AZ TRIM parameter:
If the On-Sat Az value is less than the calculated Az value:
33. Subtract targeted AZ value recorded in Step 30 from Calculated Az value recorded in step 25,
multiply by 10 and record the required AZ TRIM parameter______ _________________________
□
Example: Calculated AZ 180.0, On-Sat AZ 176.2 (180.0-176.2)*10 = Az Trim value of 0038
If the On-Sat Az value is greater than the calculated Az value:
34. Subtract Calculated AZ value recorded in Step 25 from Calculated Az value recorded in step 30,
multiply by a negative10 and record the required AZ TRIM parameter______ _________________
□
Example: Calculated AZ 180.0, On-Sat AZ 186.2 (186.2-180.0)*-10 = -0062) for an Az Trim value of -0038
35. Calculate the required
EL TRIM
parameter:
If the On-Sat EL value is less than the calculated EL value:
36. Subtract targeted EL value recorded in Step 30 from Calculated EL value recorded in step 25,
multiply by 10 and record the required AZ TRIM parameter______ _________________________
□
Example: Calculated EL 45.0, On-Sat
EL
43.5 (45.0-43.5)*10 = EL Trim value of 0015
If the On-Sat EL value is greater than the calculated EL value:
37. Subtract Calculated EL value recorded in Step 25 from Calculated EL value recorded in step 30,
multiply by a negative10 and record the required AZ TRIM parameter______ _________________
□
Example: Calculated EL 45.0, On-Sat EL 46.5 (46.5-45.0)*-10 = -0015) for an EL Trim value of -0038
38. Press the
LEFT
&
RIGHT
arrow keys simultaneously for 6 seconds to access the setup
mode parameters menu. ____________________________________________________________
□
39. Use the
LEFT
&
RIGHT
arrow keys to select appropriate digits then use the ‘
UP
&
DOWN’
arrow keys to change
EL TRIM
parameter to value recorded in Step 33.
(Pressing the Down
arrow key from 0000 will cause numbers to go negative) __________________________________________
