KVH Industries TracVision G8 - Manual (Page 85)

Improper Wiring
If the system has been improperly wired, the antenna unit will
not operate correctly. Refer to Section 2.4, “Wiring the MCU,” on
page 35 for complete system wiring information.
Vessel Turning During Startup
If the vessel turns during the two-minute startup sequence that
occurs immediately after turning on the power to the
TracVision G8, the antenna will record that variable motion as
“standing still.” This may cause the antenna to track
improperly. To solve this problem, turn the TracVision G8 off
for at least 10 seconds. Then turn the system back on, ensuring
that the vessel is either motionless or traveling in a straight line
for the two minutes immediately following power-up.
Data/Power Cable Interference
Depending on how cables are routed, conducted emissions from
the system’s data/power cable may cause reduced picture
quality on your TV screen. If the picture quality degrades only
when the TracVision G8 is operating, try installing the small
ferrite coil supplied in the kitpack. Simply clamp it onto the
data/power cable to reduce its conducted emissions (see
Figure 4-2). You might also try grounding the receiver to a
suitable earth ground.
