4.1.1 Blown Fuse or Improper 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 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,

the antenna unit will not operate correctly. Refer to

Section 2.3, “Connecting System Components” for

complete system wiring information.

4.1.2 Dew or Rain Pooling on Dome

Dew or rain can occasionally pool on the top of the radome.

While this moisture will usually be dispersed when the vehicle is

in motion, it can disrupt the signal while the vehicle is at rest.

This issue can be minimized with two approaches:

1. Using a hose, spray the dome with water to

remove the dew from the dome surface.

2. Periodically apply liquid dish detergent to the

dome surface. Wipe the full-strength detergent on

the dome and allow it to dry. This treatment will

provide a film that will help moisture bead up and

roll off the dome.

4.1.3 Satellite Signal Blocked

Satellite signals can be blocked or degraded by trees and

branches, buildings, mountains, or equipment on the vehicle

itself. Refer to Section 2.1, “Choosing the Best Location,” to make

certain that the TracVision S2 unit is in the optimal location.

Simply moving the vehicle to clear an external obstruction will

also restore signal quality.
