433MHz RECEPTION CHECK
The Temperature station will receive the temperature data within 15 minutes. If the temperature data is not
being received 15 minutes after setting up (the display shows “- - -”), then please check the following points:
1. The distance of the Temperature Station or transmitter should be at least 1.5 to 2 meters away from any
interfering sources such as computer monitors or TV sets.
2. Avoid placing the receiver onto or in the immediate proximity of metal window frames.
3. Using other electrical products such as headphones or speakers operating on the same signal frequency
(433MHz) may prevent correct signal transmission and reception.
4. Neighbours using electrical devices operating on the 433MHz signal frequency can also cause
interference.
Note:
When the 433MHz signal is received correctly, do not re-open the battery cover of either the transmitter or
Temperature Station, as the batteries may spring free from the contacts and force a false reset. Should this
happen accidentally then reset all units (see
Setting up
above) otherwise transmission problems may occur.
The transmission range is around 25 m from the transmitter to the Temperature station (in open space).
However, this depends on the surrounding environment and interference levels. If no reception is possible
despite the observation of these factors, all system units have to be reset (see
Setting up
).
