CHECKING FOR 433 MHZ RECEPTION:
In normal surroundings (for example away from interfering sources such as TV sets), the outdoor
temperature can usually be easily received within 2-1/2 minutes. If the outdoor temperature is not
displayed on the LCD after 2-1/2 minutes, then check the following:
1.
The distance of the units should be at least 1.5 - 2.0 metres away from interfering sources such as
computer monitors or TV sets.
2.
Avoid placing the units onto or in the immediate proximity of metal doors, window frames or
structures.
3.
Using other electrical products such as headphones and speakers that operate on the same signal
(433 MHz) can prevent the transmission pick up.
4.
Neighbours using electrical products operating on the 433 MHz signal can also cause interference.
In most severe cases, the reception is only possible once all other electrical products using the 433
MHz are switched off.
5.
Within thick concrete rooms such as basements and tower blocks, the 433 MHz signal can be
weakened (avoid placing near metal frames and structures).
6.
Transmission can 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 transmission
signal may be weakened. (Please bear this in mind when positioning the transmitter).
