1. Verify that tracking is ON and that the antenna is peaked on your targeted satellite (targeting calculates the
azimuth, elevation and polarization angles).
2. Follow your service provider technicians instructions to set the modem to begin transmitting a CW (pure
carrier) signal.
3. Go to the SAT SKEW parameter in the Satellite menu of the ACU.
4. Press the LEFT arrow to edit the current value.
