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. This frequency data can be
updated via the maintenance port. Please call KVH Technical
Support for details.
Incorrect or Loose RF Connectors
As part of preventive maintenance (described in Section 4.2,
“Preventive Maintenance” on page 51) 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 2.3, “Connecting the IRD(s) on page 19).
Type of Multiswitch Used
(North American Systems Only)
An active (not passive) multiswitch must always be used to
connect the TracVision 4 system to multiple IRDs. Refer to
Section 2.3, “Connecting the IRD(s)” on page 19 for directions on
proper multiswitch/multiple IRD cabling.
3.3 IRD Troubleshooting
The IRD that was provided with your satellite television service
may also be the cause of less-than-ideal operation. First check the
IRD’s configuration to ensure it is set up for the desired
programming. In the case of a faulty IRD, refer to your IRD user
manual for service and warranty information. If the IRD is both
configured properly and fully functional, contact your local KVH
dealer or service center for assistance.
3.4 Antenna Gyro and LNB Faults
Section 4, “Maintenance” on page 49 provides detailed instructions
for authorized service personnel who may be required to replace
the TracVision 4 antenna gyro or the LNB.
