INSTALLATION The Meade Instruments Semi-professional weather station (TE827NLW) operates at 433MHz radio frequency, so no wire installation is required between the main unit (receiver) and the remote weather sensors (transmitters). The remote weather sensors include a thermo-hygrometer (temperature and humidity) sensor, anemometer (wind sensor) and a rain gauge (rain sensor). All data measured by these remote sensors is transmitted to the main unit wirelessly, with the operating range up to 328 feet (100 meters) in the open area. The Anemometer and rain gauge must be placed outdoors to measure weather elements. Remote thermo-hygrometers can be placed indoors or outdoors, depending on the location where the temperature and humidity are to be measured. If you intend measuring outdoor temperature and humidity, place the remote sensor outdoors, preferably not in direct sunlight. Note: It is critical to assemble and power up all of the remote weather sensors BEFORE setting up the main unit. Note: It is critical to power up and test communication between all of the weather sensors and the main unit BEFORE permanently mounting them outside. BEFORE YOU BEGIN · We recommend using alkaline batteries for the remote weather sensors and the main unit when temperatures are above 32°F (0°C). We recommend using lithium batteries for the remote weather sensors when temperatures are below 32°F (0°C). · Avoid using rechargeable batteries. (Rechargeable batteries cannot maintain correct power requirements). · ALWAYS install batteries in the remote weather sensors before the main unit. · Insert batteries before first use, matching the polarity in the battery compartment · Remove protective plastic screen from LCD display (if any). · During an initial setup, place the main unit close to the remote weather sensors. · After reception is established (all of the remote readings will appear on the main unit's display), position the remote sensors and the main unit within the effective transmission range of up to 328 feet (100 meters). Ideally they should be placed within the line of sight of the main unit. See placement tips in the user manual for each remote weather sensor separately. · Transmission range may be affected by trees, metal structures and electronic appliances. · The main unit must be placed indoors. · The effective operating range may be influenced by the surrounding building materials and how the receiver (main unit) and transmitters (weather sensors) are positioned. · Place the remote weather sensors so that they face the main unit (receiver), minimizing obstructions such as doors, walls, and furniture. Note: When the temperature falls below freezing, the batteries in the outdoor remote weather sensors may have reduced voltage supply and a shorter effective range. We recommend using lithium batteries at temperatures of 32°F (0°C) and below. IMPORTANT: Make sure that the remote weather sensors are easily accessible for cleaning and maintenance. We recommend cleaning the remote weather sensors periodically, as the dirt and debris may affect sensors accuracy.

Atomic Time Reception The main unit synchronizes the time and date with WWVB radio clock broadcasts maintaining the atomic time precision. WWVB RADIO CONTROLLED TIME The NIST (National Institute of Standards and Technology) radio station (WWVB) is located in Ft. Collins, Colorado. It transmits an exact time signal continuously to most of the continental United States at 60 KHz frequency. The Atomic Time Clock in your weather station can receive this WWVB signal through the internal antenna from up to 2,000 miles away. Due to the nature of the Earth's ionosphere, reception can be limited during the daylight hours. The radio controlled clock will search for an alternate station that receives the atomic time signal from the NIST Atomic clock in Boulder, Colorado. The WWVB tower icon on the unit's display will flash indicating a radio signal reception from the WWVB station. If the tower icon is not fully lit, or if the time and date are not set automatically, please consider the following: · During night-time hours, atmospheric disturbances are typically less severe and radio signal reception may improve. A single daily reception is sufficient enough to keep the clock accuracy within 1 second. · Make sure the unit is positioned at 8 feet (2 meters) distance from any interference source such as a TV, computer monitor, microwave, etc. · Within concrete wall rooms such as basements or office buildings, the received signal may be weakened. Always place the Projection Clock near the window for better reception. Once the atomic time signal is received, the date and time will be set automatically, and the icon will appear. After the clock is set manually, place the main unit by the window for the better reception. The atomic clock receiver is programmed that it will continue to search for the atomic time signal daily for every hour between 1:00 am and 4:30 am. Once the time signal has been successfully received, the time and date will be updated automatically. To enable or disable the atomic time receiver: · Press and hold UP ? - if atomic time reception is activated, a triangular tower icon will start flashing next to the clock icon. If reception is disabled, the triangular tower icon will disappear. Icon
