La Crosse Technology, Ltd. Page 6Resistance: Obstacles such as walls, windows, stucco, concrete, and large metal objects can reduce therange. When considering the distance between the transmitter and the Temperature Station (330feet open air) cut that distance in half for each wall, window, tree, bush or other obstructionin the signal path. Closer is better. Do not mount the transmitter on a metal fence. This significantly reduces the effective range.Interference: Consider items in the signal path between the transmitter and the Temperature Station. Sometime a simple relocation of the transmitter or the Temperature Station will correct theinterference issue. Windows can reflect the radio signal. Metal will absorb the RF (radio frequency) signal. Stucco is held up by a metal mesh that can absorb the signal... Transmitting antennas (ham radio, emergency dispatch center, airports, military base etc.) Electrical wires (utilities, cable etc.) Vegetation is full of moisture and reduces signal. Dirt: Trying to receive a signal through a hill is difficult.Temperature StationPower Requirements 2-AA alkaline batteries power this Temperature Station.Dashes, OFL or Stuck Indoor Temperature/Humidity This is generally a power related issue. Batteries may be overpowered or underpowered. Remove batteries from TemperatureStation. Press any button 20 times. Leave the Temperature Station unpowered for 1-2 hours. Install fresh alkaline batteries with correct polarity. If the indoor temperature is still dashes or OFL, the Temperature Station may needreplacement.Inaccurate Indoor Temperature Reading Side-by-side test: Bring the outdoor transmitter in the house and place it next to theTemperature Station for 2 hours. Compare indoor and outdoor temperature. The temperature should be within 4 degrees tobe within tolerance. Look for heat sources such as sunlight, door or window frames, or reflected heat of cold.Temperature Station has missing segments This is generally a power related issue. Batteries may be overpowered or underpowered. Remove batteries from TemperatureStation. Press any button 20 times. Leave the Temperature Station unpowered for 1-2 hours. Install fresh alkaline batteries with correct polarity.
