CHECKING FOR 868 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 meters 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 (868 MHz) can prevent the transmission pick up.
4. Neighbours using electrical products operating on the 868 MHz signal can also
cause interference. In most severe cases, the reception is only possible once all
other electrical products using the 868 MHz are switched off.
