Follow the safety precautions below to reduce the risk of poor product
performance, property damage, personal injury, and/or death.
WARNING: GPS Accuracy
The GPS position and velocity accuracies are controlled by the U.S. Department
of Defence. Therefore the position accuracy described in the specifications cannot
be guaranteed.
WARNING: Correct Installation Important
The sensor must be installed and operated according to the instructions in this
owner’s guide.
WARNING: Installation Safety
Always wear safety goggles and a dust mask when installing.
WARNING: Compass Safe Distance
The sensor must be a minimum of 0.3m (1') from other standard and steering
compasses.
WARNING: Do Not Install Near Artificial Magnetic Fields
Observe a safe distance from ferrous metals and anything that can create a
magnetic field to prevent interference to the magnetic compass.
WARNING: Electrical Safety
The power supply must be OFF before making electrical connections.
WARNING: Voltage
The power supply voltage must be 9 - 40 VDC.
WARNING: Battery
Make power connections to a power source that is isolated from the engine start
battery(s). Voltage drops may cause the compass to lose information and/or
change operating mode.
WARNING: Fuse or Circuit Breaker
A safe installation requires a 0.5 amp fast-blow fuse or circuit breaker.
WARNING: Calibrating the Compass
The internal compass may need to be calibrated after the sensor is installed. Perform
the pretest to determine if calibration is necessary.
WARNING
Navigation Aid Only: The sensor is only an aid to
navigation and should never be solely relied upon. It is
not a replacement for traditional navigation aids and
techniques. Only official government charts contain all
the information needed for safe navigation.
