4.1.1 Blown Fuse or No Power
If the Antenna Unit is installed but entirely non-responsive, there
are two key factors to check as part of the troubleshooting
process:
1. Blown Fuse – The Antenna Unit is equipped with
a fuse mounted on its CPU Board. If this fuse has
blown or been broken, the Antenna Unit will not
operate. Refer to
Section 5.4.1, “PCB Removal and
Replacement,”
for details on the fuse location and
how to access the CPU Board.
2. Wiring – If the system has been improperly wired,
it will prevent the Antenna Unit from operating
correctly. Refer to
Section 2.4.2, “Connecting the
Antenna to Vehicle Power,”
for complete system
wiring information.
4.1.2 Satellite Signal Blocked
Satellite signals can be blocked or degraded by trees and
branches, buildings, mountains, overpasses, or equipment on the
vehicle itself. Refer to
Section 2.2, “Choosing the Best Location,”
to
make certain that the TracVision SA unit is in the optimal
location. Simply moving the vehicle to clear an external
obstruction will also restore signal quality.
4.1.3 Outside Satellite Coverage Zone
TracVision SA will provide outstanding reception throughout the
entire coverage area for your satellite television service of choice.
However, signal quality can be degraded as you approach the
fringe coverage areas (e.g., Northern Maine). Refer to your
satellite television service manual to check the viable coverage
area.
4.1.4 Incorrect or Loose RF Connectors
As part of preventive maintenance (described in
Section 5,
“Maintenance,”
) KVH recommends checking the Antenna Unit
cable connections. A loose RF connector can reduce the signal
quality. Refer to
Section 2.4.3, “Connecting the Antenna RF Signal
Cable to the IRD”
for directions on proper Antenna Unit to
RF cabling.
