	Problem		Solution
Dew	Dew Point reading seems	Check calibration numbers for temperature. Remember, dew point
		depends on temperature and outside humidity. Make sure they’re
	too high or too low
		working.
	Outside temperature sensor	Check calibration number and adjust if necessary. ISS or temp sen-
	reading seems too high	sor may need to be relocated. See ISS or other transmitter manual.
		Move the console out of direct sunlight. Make sure that the console
		or sensor is not in contact with an exterior wall that heats up in sun-
	Inside temperature sensor	light or when outside temperature rises. Make sure the console or
Temperature	reading seems too high	sensor is not near a heater or other internal heat source (lamps, ap-
		pliances, etc.). Also make sure the console backlight is not on.
		Check calibration number and adjust if necessary.
	Outside temperature seems	Check calibration number and adjust if necessary. Sprinklers may
	too low	be hitting the ISS radiation shield. Relocate. See ISS manual.
		Make sure the console or other temperature sensor is not in contact
	Inside temperature sensor	with an exterior wall that cools down when outside temperature

Troubleshooting Reception Problems

While we have tested the Wireless Vantage Pro2 radio extensively, each site and each installation presents its own issues and challenges. Obstruc- tions, particularly metallic ones, will often cut down your station’s recep- tion distance. Be sure to test reception between the console and ISS, in the locations you intend to install them, or before permanently mounting your ISS or other transmitter(s).
