The temperature station receiver features an adjustable LCD screen, which relays conditions including the time, date, indoor and outdoor temperatures, and the minimum and maximum temperature recordings. Temperatures can be displayed by either Fahrenheit or Celsius degrees, while time of day can be viewed in 12- or 24- hour formats. To monitor outdoor conditions, a LaCrosse TX6U sensor is included. The sensor transmits information to the receiver from up to 80 feet at a 433.92MHz frequency. Transmission through walls reduces this range. While the sensor fares well in fog or mist, shelter it to prevent rain damage. The temperature system measures temperatures ranging from +32 to +140 degrees F. The outdoor sensor registers temperatures ranging from -21.8 to +157.2 degrees F. With a radio-controlled time and date function, the temperature station automatically updates for Daylight Savings Time or travel to a new time zone. The temperature station hangs or can stand upright on a tabletop. The outdoor sensor comes with a mounting hardware. Separate purchase of four AA alkaline batteries is required to power the temperature station and sensor. Replace batteries annually for best results. The weather station accommodates up to three outdoor sensors. LaCrosse encloses a thorough manual for setting up the weather station. This product is covered under a limited one-year warranty. The base monitor measures 5-2/3 by 3-1/45 by 1-1/4 inches while the sensor is approximately 5 by 1.5 by 4/5 inches. This item weighs 2 pounds upon shipping. --Jessica Reuling
