*When the wind speed is less than 2 m/s (4.6 MPH) and/or air temperature is below 0C (32F),

wind, temperature, and relative humidity readings will be less accurate.

**Wet conditions include moisture, rain, frost, dew, snow, ice and/or sea spray in the wind channel.

***Temperature and relative humidity reports invalid during heater operation.

****Airmar has made the address claiming modifications to enable compatibility with the ISO 11783

communication protocol for the agriculture industry that is based on the SAE J1939 protocol.

Only applicable to NMEA 0183 output. The end is an Airmar 8-pin connector, which can be removed to connect to a bare wire device. !!!!—-
