La Crosse Technology, Ltd. Page 8 Batteries often resolve the connection. Distance/Resistance can cause loss of connection between the sensor and theRain station. Reorientation of the Rain station 90 degrees towards the outdoor sensor mayprovide better reception by the antenna. Try the factory restart.Inaccurate Outdoor Temperature Reading The outdoor sensor reads the environment. When mounted in the home it willread inside temperature. When the sensor reads high during the day but not at night it is a positioningproblem. Side-by-side test: Bring the outdoor sensor in the house and place it next tothe Rain station for 2 hours. Compare indoor and outdoor temperature. The temperatures should be within 4degrees to be within tolerance. If the sensor reads correctly when next to the rain station then try a differentlocation outside. Look for heat sources such as sunlight, door or window frames, or reflectedheat.Intermittent Outdoor Temperature RF (radio frequency) communication may come and go occasionally. This can benormal in some environments (e.g. moister climates). If sensor signal is lost,please wait 2-4 hours for the signal to reconnect on its own. Move the outdoor sensor to a closer location. Freezer test: Confirm the rain station is reading the correct outdoor sensor.Place the sensor in the freezer for an hour and watch the temperature drop onthe rain station. Indoor distance test: Please complete the Restart with sensor and rain station5-10 feet apart and inside to establish a strong connection. After 15 minutes if there is a reading in the outdoor temperature area, move thesensor to another room with one wall between the sensor and the rain station.Observe to see if the temperature remains on consistently for 1-hour. If the temperature remains on while in the house then it is likely adistance/resistance issue. Move the sensor to different locations outside to find alocation where the temperature reading will hold. Distance/Resistance can cause loss of sensor signal. Check Batteries.Outdoor Sensor Fell and No Longer Works If there is no physical damage to the outdoor sensor, the fall may not havecaused internal damage. An outdoor sensor that has fallen into a puddle or other standing water or snowmay have water damage. Sensors are water resistant, not waterproof. A fall can shock the sensor or the batteries in the sensor.
