GyroTrac-specific Issues

The GyroTrac is designed for reliable, easy use. This section
provides a brief overview of some potential operational issues.
Issue 1:
System is installed correctly and power is available, but the
system is non-functional.
Solution:
Check the 4-amp fuse within the ADCU. Remove the two screws
securing the top and the base of the ADCU, and remove the
ADCU's top cover. The fuse is secured in brackets on the upper
printed circuit board (PCB). Remove the damaged fuse and
replace with a new, functional fuse.
Issue 2:
System fails the startup routine and the ADCU displays "Errors
Detected."
Solution:
GyroTrac will not operate unless the system passes the startup
self-tests. The following actions may be taken in this instance.
•
Shut down the system, then restore power.
•
Shut down the system and verify proper wiring as
detailed in Section 2.6, "Wiring the ADCU" on
page 29.
•
Contact a KVH dealer or distributor for further
assistance.
Issue 3:
GyroTrac is connected to a TracVision G4 system but there is no
communications between GyroTrac and the antenna, and you are
unable to access antenna-specific menus on the ADCU.
Solution:
Verify that GyroTrac is configured as a TracVision component, as
detailed in "Selecting TracVision or GyroTrac-only Operations"
page 76.
