Calibration - Winegard WV750 Product Manual

6. The software will show a progress bar and indicate when it is finished updating.
Do not go to step 8 until this finished status is displayed.
7. Cycle the power on the controller when the system returns to the Main Menu.
8. Check the version of the software by navigating to one of the screens described
in section 7.3.

8.4 - Calibration

There are several different systems that require calibration. The first group of
calibration procedures are factory set calibrations and will only be required if the
Outdoor Unit (ODU) or the Azimuth Position Sensor are replaced.
These procedures include calibration of the azimuth position sensor or calibration of
the Vehicle Attitude Board (pitch and roll).
The second calibration procedure involves systems that may require periodic
calibration. This includes setting the antenna system's home position. This procedure
can be accomplished using either the USB keyboard or the Indoor Unit (IDU) in normal
operation.
8.4.1 - Calibration of the Azimuth Home Position
This procedure should be performed if the LNB arm does not line up with the stow
position bracket or an AZ sensor error is detected during a stow routine. This
procedure requires a USB keyboard (or alternate method). The system must be in
debug mode as described earlier in this document.
It is very important that the antenna elevation is high enough that the LNB arm will
clear all obstacles.
1. The IDU screen should display "trk>".
2. Hold down the control key (ctrl), press "t", release both keys and then press enter.
a. The IDU screen should change to the capital "TRK>" prompt.
3. Type "dc" and press enter.
a. The IDU prompt should change to "DC>"
4. Type "v 2 100" and press enter.
a. The LNB arm should lift off of the stow tray.
5. Type "s" and press enter to stop the motor.
a. Verify that the LNB arm will not hit any obstacles when the azimuth motor is
engaged.
b. If the LNB arm must be raised farther, type "v 2 100". Continue raising the
antenna until the LNB arm is at a safe elevation.
6. Center the azimuth.
a. Visually inspect the front of the antenna assembly to see if the unit is aligned
in the middle of the stow tray.
b. If the unit is aligned, skip to step 6.
c. At the "DC>" prompt, type "p 0 -500" and press enter. This will rotate the
azimuth motor clockwise past the magnetic sensor.
