4.1.4 Outside Satellite Coverage Zone
TracVision SA will provide outstanding reception throughout the
entire coverage area for your satellite television service of choice.
However, signal quality can be degraded as you approach the
fringe coverage areas (e.g., Northern Maine). Refer to your
satellite television service manual to check the viable coverage
area.
4.1.5 Incorrect or Loose RF Connectors
As part of preventive maintenance (described in Section 5,
“Maintenance,” ) KVH recommends checking the Antenna Unit
cable connections. A loose RF connector can reduce the signal
quality. Refer to
Section 2.4.4, “Connecting the Antenna RF Signal
Cable to the IRD” for directions on proper Antenna Unit to
RF cabling.
4.2 IRD Troubleshooting
The IRD that was provided with your satellite television service
may also be the cause of less-than-ideal operation.
4.2.1 IRD Data Port or Cable/Wiring
Refer to Section 2.4.1, “Connecting the Antenna Unit Data Cable to
the IRD” and your IRD user manual to confirm that the IRD is
properly connected to the Antenna Unit and the television.
4.2.2 AC Power Fluctuating
If the system periodically displays a picture for less than one
minute, then enters Search Mode 1, the IRD data port may be
locked up as the result of power fluctuations and will require a
reset. This can be verified by hooking up a PC to the data port
and checking for error messages. Reset must be done by:
1. Completely shutting down DC power to the
antenna.
2. Remove the AC source, either at the breaker or by
unplugging the IRD.
3. Wait at least 10 seconds before restoring power
first to the IRD and then to the antenna.

Troubleshooting
54-0149 Rev. D
The long-term fix, typically done at
original system installation, is to
install an Uninterruptible Power
Supply (like those available for use
with computer systems) on the IRD.
Be sure to specify a UPS with
adequate available current for all
devices attached to it. (An IRD
draws approximately 200 watts.)
Baseline RF levels are included as
part of the startup sequence
provided in
Appendix E .
