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
two fuses mounted on its CPU Board. If either of
these fuses 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
locations and how to access the CPU Board.
2. Wiring – If the system has been improperly wired,
the antenna unit will not operate corr
ectly. Refer to
Section 2.3, “Connecting System Components
,”
for
complete system wiring information.
4.1.2 Incorrect Satellite Configuration
The satellite configuration on your receiver must match the
satellite setting on the TracVision R5/R4 system.
• Satellite A on the TracVision R5/R4 must be the
same satellite as Receiver Alternative 1 (or A,
based on your receiver) and must be assigned the
Receiver DiSEqC 1 setting.*
• Satellite B on the TracV
ision R5/R4 must be the
same satellite as Receiver
Alternative 2 (or B,
based on your receiver) and must be assigned the
Receiver DiSEqC 2 setting
.*
* The DiSEqC settings only apply to European systems.
Refer to your receiver user manual for complete instructions on
configuring your r
eceiver

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 R5/R4 unit is in the optimal
location. Simply moving the vehicle to clear an external
obstr
uction will also r
estor
e signal quality
