Radar Interference
The TracVision M5/M7 antenna must be kept out of line with nearby
radars, as their energy levels might overload the antenna's front-end
circuits. Refer to the TracVision M5/M7 Installation Guide for details,
or visit any KVH-authorized dealer or distributor for assistance. To

Satellite Frequency Data Changed
If some channels work, while one or more other channels do not, or if
the antenna cannot find the selected satellite, the satellite's frequency
data might have changed. You can visit any KVH-authorized dealer or
distributor for assistance. To find a KVH-authorized dealer near you,

Vessel Turning During Startup
If you turn the vessel during the first minute after system startup, the
gyro calibration that occurs during startup might be invalid, causing
the TracVision M5/M7 system to track improperly. To solve this
problem, simply turn off the TracVision M5/M7 system for at least ten
seconds. Then turn on the TracVision system, ensuring the vessel is
either motionless or traveling in a straight line for the first minute after
startup.
Insufficient Power
If the power cable to the antenna unit is more than 50 ft (15 m) long,
the power level can decrease over the length of the cable, resulting in a
voltage level at the antenna that is too low to power the system. Refer
to the TracVision M5/M7 Installation Guide for details on supplying
adequate power to the antenna, or visit any KVH-authorized dealer or
distributor for assistance. To find a KVH-authorized dealer near you,
visit www.kvh.com/wheretogetservice.
Improper Wiring
If the system has been improperly wired, the antenna will not operate
correctly. Refer to the TracVision M5/M7 Installation Guide for
complete system wiring information, or visit any KVH-authorized
dealer or distributor for assistance. To find a KVH-authorized dealer
near you, visit www.kvh.com/wheretogetservice.
