When stopping in an area where the antenna will be blocked from the satellite (i.e., gas stations,
parking structures, heavy foliage, etc.) it is recommended the antenna be turned off and restarted
when the antenna' s line of sight to the satellite is clear.
When the vehicle is stationary for long periods of time, turn antenna system off after acquiring
signal. Turning system off will reduce power drain and extend operating life of antenna and vehicle
battery.
If the antenna loses track for approximately two (2) minutes, it will automatically re-initialize, as
indicated by the "INT-REV XXXX" message. The vehicle should be kept in a straight path during
this re-initializing mode.
If there is excessive vehicle motion during the initializing process, the system will remain in the
initializing mode until motion has reduced to an acceptable level, or until five (5) minutes has
elapsed.
If the antenna loses track for five (5) minutes or more switch the power off and on again to reboot
the system.
The antenna can move 360° from the center position in either direction. The word "repositioning"
will appear when the antenna unwraps the wiring bundle. When the antenna repositioning is
complete, the system will start tracking the satellite again. This process will take approximately
five (5) seconds.
Sharp turns or curves at high acceleration may result in brief signal loss. This is normal operation.
Signal should reappear in a few seconds.
Do not attempt to remove the radome (cover). Contact with the internal components may cause
serious damage to the unit and void any warranties.
Clean the outside radome surface of bugs, debris and other contamination with water and a mild
detergent periodically.
In heavy dew conditions operation can be optimized by wiping the excess moisture from the
radome or just spraying the unit off with a water hose. The vehicle may be driven to blow the
moisture from the radome. The antenna radome may be treated with rain repellent to minimize
moisture buildup.
