Airmar H2183—Heading Sensor - Manual (Page 16)

Maintenance
CAUTION: Do not disassemble the sensor. There are no user-serviceable parts
inside. Removing the screws from the sensor (part A) will damage the waterproof
seal, thus voiding the warranty.
CAUTION: Do not immerse in water or pressure wash. Doing so may allow water
to infiltrate the sensor, voiding the warranty.
Since the sensor has no moving parts, it requires minimal maintenance. Clean the
sensor with a soft damp cloth and mild household detergent.
Troubleshooting
Problems with the Sensor
• Is there power to the sensor?
• Are all the connections tight?
• Is the cable-run free of kinks or damage?
• Is the wiring correct?
• Is there damage to the sensor?
• Is the sensor exposed to excessive vibration?
Inaccurate Compass Readings
• Is the sensor installed facing forward and parallel to the centerline of the
vehicle/boat?
• Does the compass need to be calibrated?
• Is there interference from ferrous metals, electronic equipment, electric motors,
batteries, or cables that are creating a magnetic field?
• Is the sensor mounted near the vehicle/boat’s center of gravity?
Problems with the Rate Gyro or Accelerometer
• Is the sensor installed reasonably level with the waterline?
• Is the sensor mounted near the center of the vehicle/boat’s fore-aft axis?
