3.1.1 Blown Fuse or Wiring
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 4.4, "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. Section 2.3, "Wiring the TracVision 4
System," provides complete system wiring
information.

3.1.2 Vessel Turning During Startup

If the vessel turns during the 60-second startup and
initialization sequence that occurs immediately after turning
on the power to the TracVision 4 unit, the antenna gyro will
record that variable motion as "standing still." This may cause
the antenna to track improperly. To solve this problem, turn
TracVision 4 off for at least 10 seconds. Turn the system back
on, making certain that the vessel is either motionless or
travelling in a straight line for the 60 seconds immediately
following power-up.

3.1.3 Incorrect Satellite Configuration

(European Systems Only)

The satellite configuration on European IRDs must match the
satellite settings on the TracVision 4 system.
• Satellite A on the TracVision 4 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 4 must be the same
satellite as IRD Alternative 2 (or B, based on your
IRD) and must be assigned the IRD DiSEqC 2
setting.
