Satellite Frequency Data Changed
If some channels work, while one or more other channels do not,
or the antenna cannot find the satellite, the selected satellite's
frequency data may have changed. To update this frequency
data, refer to "Updating Satellite Frequency Data" on page 88.
Incorrect or Loose RF Connectors
As part of preventive maintenance (described in Section 5.2,
"Preventive Maintenance" on page 103) KVH recommends checking
the antenna unit's cable connections. A loose RF connector can
reduce the signal quality. In addition, if you are unable to switch
satellites using your IRD remote, make sure that your IRD's RF
cable is connected to the antenna baseplate connector labeled
"RF1" (see Section 2.5, "Connecting the IRD(s) on page 26).
Type of Multiswitch Used
(North American Systems Only)
An active (not passive) multiswitch must always be used to
connect the TracVision G4 system to multiple IRDs. Refer to
Section 2.5, "Connecting the IRD(s)" on page 26 for directions on
proper multiswitch/multiple IRD cabling.
