Care & Maintenance
Display Unit Care
Clean with a soft, damp cloth. Do not use caustic cleaners or abrasives. Keep away from dust,
dirt and moisture. Clean ventilation ports regularly with a gentle puff of air.
3-in-1 Sensor Care
Clean the Sensor
Clean with a soft, damp cloth. Do not use caustic cleaners or abrasives.
Insect Prevention
Insects may cause obstructions and interrupt data by nesting in or on the 3-in-1 sensor. To limit
this problem, spray sensor housing with a household insect repellent. Note: Insect repellent
should not be sprayed on the internal components or into the sensor. Consult insect repellent
instructions prior to use.
Snow & Freezing Weather
The 3-in-1 sensor will not be damaged by freezing conditions.
Clean the Wind Anemometer
Remove foreign matter from the outside of the sensor for free movement of the wind
anemometer. If needed, use a small amount of spray lubricant, clear silicone or graphite
powder on the anemometer for improved movement. Note: Spray lubricant, clear silicone or
graphite powder should not be sprayed on the internal components or into the sensor.
