Radar Interference
The energy levels radiated by radar units can overload the
antenna’s front-end circuits. Check with your installer to make
certain that the TracVision 4 antenna unit is in the optimal
location with regard to your radar unit.
Satellite Frequency Data Changed
If some channels work while one or more other channels do not,
or if the antenna is unable to find the satellite, the selected
satellite’s frequency data may have changed. This frequency data
can be updated via the maintenance port. Contact your local
KVH dealer or service center for assistance.
Incorrect or Loose RF Connectors
A loose RF connector can reduce the quality of the satellite signal.
Also, if you cannot switch satellites using your IRD remote, your
IRD may be connected to the wrong antenna baseplate connector.
The TracVision 4 Technical Manual provides instructions for
authorized service personnel who may need to check the RF
connections. Contact your local KVH dealer or service center for
assistance.
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. Contact your
KVH dealer or service center for assistance.
