exchanged in only one of the devices (i.e. the remote
sensor) the signal can’t be received or can’t be received
correctly.
Note, that the effective range is vastly affected by building
materials and position of the main and remote units. Due to
external influences (various RC devices and other sources
of interference), the maximum distance can be greatly re-
duced. In such cases we suggest to position the main unit
and the remote sensor at other places. Sometimes all it
takes is a relocation of one of these components of a few
inches! Though the remote unit is weather proof, it should
be placed away from direct sunlight, rain or snow.
