LOW BATTERY INDICATOR
The low battery indicator of the Weather Center and the Thermo-hygro sensor will be
displayed at the top and bottom portion of the LCD respectively when the battery
power is low. It is recommended to replace the batteries in all units on an annual
basis to ensure optimum accuracy of the system.

OUTDOOR TRANSMITTER 915 MHz RECEPTION
The outdoor temperature, humidity, wind data and rainfall are transmitted from the
Thermo-hygro sensor every 4.5 seconds. The Weather Center will then be
synchronized to the Thermo-hygro sensor to receiver outdoor data. The transmission
range (up to 330 feet) of the Outdoor Thermo-hygro sensor may be affected by the
ambient temperature. At cold temperatures the transmitting distance may be
decreased. Please keep this in mind when placing the transmitter.
If the outdoor data are not being received within 30 seconds after setting up (or the
outdoor display shows “- - -“ in the outdoor section of the Weather Center after
consecutive failed attempts during normal operation). Please check the following
points:

Note:
When the 915 MHz signal is received, do not re-open the battery compartment cover
of either the transmitter or Weather Center, as the batteries may spring free from the
contacts and force a false reset. Should this happen accidentally then reset all units
(see Setting up above) otherwise transmission problems may occur.

An ideal mounting place for the Thermo-hygro sensor would be the outer wall beneath
the extension of a roof, as this will protect the sensor from direct sunlight and other
extreme weather conditions.
To wall mount, use the 2 screws to affix the wall bracket to the desired wall, plug in
the Thermo-hygro sensor to the bracket and secure both parts by the use of the
supplied screw and ensure that the cables from the wind and rain sensors are
correctly plugged in otherwise data transmission errors could occur.

Firstly, check that the wind-fan and the wind-vane can rotate freely before fixing the
unit. For correct and accurate readings it is important to mount the sensor so that the
front (marked E) is pointing in East-West direction. The wind sensor should now be
