NOTE!
Please position the external sensor in such a way
that it is not exposed to extreme heat or cold.
In extremely cold conditions the batteries, and
therefore the transmission signal, will be adversely
affected. We recommend you operate the weather
station with ordinary batteries as opposed to
rechargeable batteries.
