On the sensor may not directly rain - placed under the window reveals, on the balcony, under the roof, shelter, etc. Using the specified batteries - do not use sensors, rechargeable batteries, because they have a lower voltage (1.2V). Use alkaline batteries with 1.5V voltage. Any metal objects reduces the transmission power. Therefore, do not place the sensor on the parapet and other metal structures, etc. Keep in mind that the temperature above the ground and at a height of several meters is not the same! Transmission range depends on local conditions and electromagnetic interference in the field. When passing through the building structure is to control a range of radio waves is falling rapidly. Sometimes doing the problem and retracted blinds. Beware of heating in the floors, where underneath the aluminum foil - the signal is shielded. When replacing the batteries, insert new batteries into the station and sensors, sensor leave the thermometer in the vicinity of a few minutes before the thermometer displays the data from the sensor.
