[. . . ] 4. 5. 6. 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 (868MHz) can prevent the transmission pick up. Neighbours using electrical items operating on the 868MHz signal can also cause interference. [. . . ] IMPORTANT NOTE: · By the time of inserting the batteries into the next transmitter, the outdoor temperature and humidity readings from the previous transmitter should be received. Always ensure that the readings are received from one transmitter before activating the next. · Each succesfull 868MHz transmission from the transmitter to the Weather station should take approximately thirty seconds. If no temperature readings are received within a minute after inserting the batteries into the transmitter, then reset all units (see Resetting below). · The Weather station allows sufficient time for setting up process. If setting up has taken more than 8 minutes, then the start up problems may occur because the Weather station may not attempt to receive the 868MHz signal after this period. · Transmitter need not to be activated in any set order, except that each transmitter temperature and humidity readings before activating the next transmitter. 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 . 868MHZ-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: 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. Note: Remember when inserting, the Weather station and all the transmitters have to be reset and insert the batteries into the Weather station first. WALL MOUNTING THERMO-HYGRO TRANSMITTER: Each transmitter is supplied with 2 wall mounting screws and plastic anchors. Secure the wall base onto a desired wall using the screws and plastic anchors. Insert the transmitter to the wall base. Note: Before permanently fixing the transmitter wall base, pace all units in the desired locations to check that the outdoor temperature and humidity readings are receivable. [. . . ] · Do not make any repairs to the unit. Please return to the original point of purchase for repair by a qualified engineer. Opening and tampering with the units may invalidate its guarantee.
