Wind Direction
On the edge of the wind direction sensor, there are four letters - "N", "E", "S" and "W" representing the
directions North, East, South and West. The wind direction sensor has to be adjusted so that the directions
on the sensor are matching your real location. A permanent wind direction error will be introduced when
the wind direction sensor is not positioned correctly during installation.
Batteries
Note: Incorrectly inserting the batteries may cause a fault and invalidate the warranty so take care to
insert them with the correct polarity.
Note: Many rechargeable batteries are 1.2V and as such are not suitable for this unit which requires 1.5V
batteries. Rechargeable batteries also often leak their peak charge quickly which can cause reduced
transmission range. As such we recommend avoiding the use of rechargeable batteries.
Note: The performance of Alkaline batteries can be significantly reduced in colder environments resulting
in loss of signal. In this case we recommend the use of Lithium batteries in the thermo-hygro sensor.
Low Battery Indicator
The transmitter low battery indicator may illuminate when temperatures are outside the range
of 10-35C. This does not necessarily indicate low batteries and will switch off once the temperature
returns to this range (also see note above on the use of Alkaline batteries).
