Troubleshooting Reception Problems
While we have tested the Wireless Vantage Pro2 radio extensively, each site
and each installation presents its own issues and challenges. Obstructions, par-
ticularly metallic ones, will often cut down your station's reception 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 trans-
mitter(s).

Check calibration number and adjust if necessary. ISS or temp sen-
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-
light or when outside temperature rises. Make sure the console or
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.
Check calibration number and adjust if necessary. Sprinklers may
be hitting the ISS radiation shield. Relocate. See ISS manual.
Make sure the console or other temperature sensor is not in contact
with an exterior wall that cools down when outside temperature
drops. Make sure the console or other temperature sensor is not
near an air conditioning vent. Check calibration number and adjust
if necessary.
• Wireless model - check reception. See Reception Problems
below.
• Cabled model - cable may be faulty.
If these steps do not reveal the problem, the anemometer may be
faulty. Call technical support for return authorization.
Usually an ISS problem, especially if outside temperature is dashed
out as well. See the ISS manual for troubleshooting information
Check calibration numbers for temperature. Remember, wind chill
depends on temperature and wind speed. Make sure they're work-
ing.
Check calibration numbers for temperature. Remember, the heat in-
dex depends on temperature and outside humidity. Make sure
they're working.
Make sure cable-tie is removed from rain collector. See the ISS
manual.
Check your latitude, longitude, time zone, and daylight savings time
settings. Sunrise and sunset times are calculated from the console
