Follow the safety precautions below to reduce the risk of poor product 
performance, property damage, personal injury, and/or death.

WARNING

Correct Installation Important

The sensor must be installed and operated according to the instructions in this 
owner’s guide.

WARNING

Steel Vessel

Do not install the Heading Sensor within a steel hull because it is a ferrous 
(magnetic) material.

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 Field

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 - 24 VDC.

WARNING

Fuse or Circuit Breaker

A safe installation requires a 0.5 amp fast-blow fuse or circuit breaker.

WARNING

Battery

Make power connections to a power source that is isolated from the engine start 
battery(s). Voltage drops may cause the sensor to lose information and/or change 
operating mode.

WARNING

Installation Safety

Always wear safety goggles and a dust mask when installing.

WARNING

Calibrating the Compass

The internal compass may need to be calibrated on the water after the sensor is 
installed. Perform the pretest to determine if calibration is necessary.

WARNING

:

This product contains chemicals known to the State of California to cause cancer 
and/or reproductive harm.

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, 
and human judgement. Only official government nautical 
charts contain all the information needed for safe navigation.
