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, particularly metallic 
ones, 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, before perma-
nently mounting your ISS or other transmitter(s).
The console’s reception status displays at the lower right corner of the screen.

Outside temperature sen-

sor reading seems too high

Check to see if ISS is near mechanical or radiant heat source. 

Check calibration number and adjust if necessary. ISS or temp 

sensor may need to be relocated. See ISS or other transmitter 

manual.

Inside temperature sensor 

reading seems too high

Move the console out of direct sunlight. Make sure that the con-

sole or sensor is not in contact with an exterior wall that heats 

up in sunlight or when outside temperature rises. Make sure the 

console or sensor is not near a heater or other internal heat 

source (lamps, appliances, etc.). Also make sure the console 

backlight is not on. Check calibration number and adjust if nec-

essary.

Outside temperature 

seems too low

Check calibration number and adjust if necessary. Sprinklers 

may be hitting the ISS radiation shield. Relocate. See ISS man-

ual.

Inside temperature sensor 

reading seems too low

Make sure the console or other temperature sensor is not in 

contact with an exterior wall that cools down when outside tem-

perature drops. Make sure the console or other temperature 

sensor is not near an air conditioning vent. Check calibration 

number and adjust if necessary. 

Wind direction reading is 

dashed out

•

Wireless model - check reception. See Reception Prob-

lems below.

•

Cabled model - cable may be faulty.

If these steps do not reveal the problem, the anemometer may 

be faulty. Call technical support.

Wind direction always says 

north

Usually a problem in the ISS, either with the transmitter or ane-

mometer cable. See the ISS manual for troubleshooting infor-

mation.

Wind chill reading seems 

too high or too low

Check calibration numbers for temperature. Wind chill depends 

on temperature and wind speed. Make sure they’re working.

Heat Index reading seems 

too high or too low

Check calibration numbers for temperature. The heat index de-

pends on temperature and outside humidity. Make sure the sen-

sors are working.

No rain readings

Make sure cable-tie is removed from inside the rain collector. 

See the ISS manual. 

Readings are too high

Can be caused by high thin cirrus clouds. 

Incorrect times for sunrise 

and sunset

Check your latitude, longitude, time zone, and daylight savings 

time settings. Sunrise and sunset times are calculated from the 

console using all of these settings.
