Using the ADCU Interface

3.1 Startup and Self-test
1. Turn on the IRD and television.
2. If a GPS receiver is connected, ensure that it has
obtained an accurate position.
3. Apply operating power to the ADCU.
4. Wait while the system conducts a brief self-test
sequence. Test status messages are displayed on
the ADCU for approximately two seconds each.
If the self-testing routine detects faults in any of the first four self-
tests, the screen pictured in Figure 3-2 is displayed. Operation
halts at this point and the GyroTrac cannot operate. The unit
should be returned to your local authorized KVH dealer,
distributor, or service center.

Startup and Self-test Sequence
The absence of valid GPS data is
not a fault; the status message
merely indicates that valid GPS
data is not present and that those
navigation functions that use GPS
inputs are not available.
The GPS must be turned on first for
TracVision G4 to use the GPS
position data during initialization.
