User manual LA CROSSE TECHNOLOGY TX4-433MHZ

[. . . ] Firstly, open the battery cover to your Weather Station and checking the correct polarization, insert 2 x AA, IEC LR6, 1. 5V batteries into the battery compartment. Replace the cover and ensure that the batteries do not spring free from the contacts, otherwise start up problems may occur. Slide open the battery cover of the transmitter as indicated above and insert 2 x AA, IEC LR6, 1. 5V batteries into the battery compartment and replace cover. [. . . ] Each transmission signal received by the Weather Station will be indicated by the satellite transmission icon and a 1, 2 or 3 icons (i. e transmitter 1, 2 or 3) on the LCD (unless only 1 transmitter is used) The icons are located on the Weather station LCD in between the outdoor temperature and humidity readings. · Always insert batteries into the Weather station first before the transmitters otherwise transmission problems will occur . 433MHZ-EMPFANGSTEST: In normal surroundings (for example, away from interfering sources such as TV sets), the outdoor temperature and humidity readings from the transmitter can usually be received within 1 minute of setting up. Should this not be the case, then check the following: The distance of all units should be at least 1. 5 ­ 2. 0 meters away from interfering sources such as computer monitors or TV sets. Avoid placing the units onto or in the immediate proximity of metal doors and window frames or structures. Using other electrical products such as wireless headphones and speakers that operate on the same frequency signal (433MHz) can prevent the transmission pick up. Neighbours using electrical items operating on the 433MHz signal can also cause interference. In most severe cases, readings will only be received once all the other electrical items using 433MHz are switched off. Within thick concrete rooms such as basements and tower blocks, the signal is naturally weaker. Should this happen, then place the Weather station closer to a window or point its front or back in the general direction of the transmitters (avoid placing near metal frames and structures). Transmission may be affected by exposure to extreme temperature conditions. For example, if the weather has been extremely cold (under -25ºC) for an extended period of time, then the 433MHz may be weakened. Please bear this in mind when positioning the transmitter (see Maintenance below). SPECIFICATIONS: · Recommended operating temperature: -29. 9ºC to +69. 9ºC with 0. 1ºC resolution · Transmission temperature update : approximately every 1 minute · Relative Humidity measuring range : 1% to 99% with 1% resolution · Transmission frequency : 433. 92 MHz · Temperature transmitting range up to: 25 meters (in open space and free from interference) · Transmission power source : 2 x AA, IEC LR6, 1. 5V batteries · Battery life: approximately 12 months (Alkaline batteries recommended) · Dimensions (L x W x H) : 60 x 73 x 121 mm Note: For full operating instructions, please refer to the main instruction manual enclosed with the Weather station. RESETTING: 1. Remove the batteries from all the transmitters and the Weather station. Wait at least 30 seconds and repeat the procedures specified in Setting up above. Always wait at least 30 seconds before reinserting the batteries, otherwise start up problems may occur. [. . . ] · Avoid areas where the transmitter(s) can be exposed to sudden changes in temperature, i. e. direct sunlight, extreme cold and wet/moist conditions as this may lead to rapid changes which may reduce the accuracy of the readings. Do not use solvents or scouring agents and do not submerge into water. [. . . ]
