TROUBLESHOOTING
Problem: The LCD is faint.
Solution: 1) Set the LCD contrast to a higher level.
2) Replace batteries.
Problem: No outdoor temperature/humidity is displayed.
Solution: 1) Remove all batteries, reinsert into the remote thermo/hygro sensor
first, then into the indoor weather station.
2) Place remote thermo/hygro sensor closer to the indoor weather
station.
3) Be sure all batteries are fresh.
4) No other interfering sources are being used (such as computer
monitors, TV sets, headphones, or speakers) in the vicinity. The
signal travels in a straight line, an electrical source near that "line"
may cause interference.
Problem: Temperature, humidity, or air pressure is incorrect.
Solution: 1) Check/Replace batteries.
2) If multiple remote sensors are in use, check location with
corresponding "boxed numbers."
3) Move away from sources of heat/cold.
4) Adjust relative air pressure to a value from a reliable source (TV
radio, etc.).
5) The indoor weather station and remote sensors are calibrated at the
factory. If there is a consistent problem, please call La Crosse
Technology.
Problem: "- -" in humidity display.
Solution: 1) Humidity is below 20% or above 95%.
2) TX3U or TX3UP is used for remote temperature.
Problem: WWVB time and date will not set or update
Solution: 1) Wait until overnight for signal to be received
2) Move indoor weather station away from sources of electricity
3) Place indoor weather station in window facing Colorado
4) The first reception is most difficult, as the indoor weather station
needs five continual minutes of clear signal reception. After the
initial time/date set, the indoor weather station only requires one
full minute of clear reception each night.
