4.1.1 Blown Fuse or Improper Wiring
If the Antenna Unit is installed but entirely non-responsive, there
are three 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
for details on the fuse location and
how to access the CPU Board.
2. Wiring – If the system has been improperly wired,
the Antenna Unit will not operate correctly. Refer
to
Section 2.3, “Wiring the TracVision S3 System,”
for
complete system wiring information.
4.1.2 Incorrect Satellite Configuration
The satellite configuration on your IRD must match the satellite
setting on the TracVision S3 system.
•
Satellite A on the TracVision S3 must be the same
satellite as IRD Alternative 1 (or A, based on your
IRD) and must be assigned the IRD DiSEqC 1
setting.*
•
Satellite B on the TracVision S3 must be the same
satellite as IRD Alternative 2 (or B, based on your
IRD) and must be assigned the IRD DiSEqC 2
setting.*
*
The DiSEqC settings only apply to European systems.
Refer to your IRD user manual for complete instructions on
configuring your IRD.
4.1.3 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 2.1, “Choosing the Best Location,”
to
make certain that the TracVision S3 unit is in the optimal location.
Simply moving the vehicle to clear an external obstruction will
also restore signal quality.
