Causes and Remedies for
Common Operational Issues
There are a number of common issues that can affect the signal
reception quality or the operation of the TracVision 4. The
following sections address these issues and potential solutions.
Blown Fuse, Low Power, or Wiring
If the antenna unit is installed but entirely non-responsive, there
are three key factors to check as part of the troubleshooting
process:
Blown Fuse
With the system powered on, move the antenna
reflector slowly by hand. If the reflector does not
move freely, a fuse is not the problem. If the
reflector does move freely, one of the two fuses
mounted on the CPU Board may have blown or
been broken.
The TracVision 4 Technical Manual
provides detailed instructions for authorized
service personnel who may be required to replace
a fuse.
Contact your local KVH dealer or service
center for assistance.
Low Power
If the power cable to the antenna unit is more than
50 ft (15 m), the power levels can decrease over the
course of the cable, resulting in a voltage or
current level at the antenna unit that is too low to
power the system properly.
The TracVision 4
Technical Manual provides detailed instructions for
supplying adequate power to the antenna unit.
Contact your local KVH dealer or service center
for assistance.
Wiring
If the system has been improperly wired, it will
not operate correctly.
The TracVision 4 Technical
Manual provides detailed instructions for
authorized service personnel who may be required
to check the wiring.
Contact your local KVH
dealer or service center for assistance.
If you need help troubleshooting
your system, please contact an
