OUTDOOR TRANSMITTER 915 MHz RECEPTION CHECK
The outdoor temperature, humidity, wind data are transmitted from thermo-hygro
transmitter every 4.5 seconds; the rainfall data are transmitted from the rain sensor
(optional) every 6.25 seconds. The receiver will be synchronized to the thermo-hygro
transmitter and rain sensor (optional) then. The transmission range (up to about 330 feet
/100 meters in open air) of the thermo-hygro transmitter/ rain 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 and the rain sensor.
If (1) the outdoor data is not being received within first several minutes after setting up; (2)
the outdoor display always shows "- - -" on the outdoor display; or (3) the reception icon of
thermo-hygro transmitter (Mode 1) and rain sensor (optional) (Mode 2) is not displayed on
the display, check the following things:
1. The distance of the Weather Station or transmitter/ rain sensor should be at least 5
to 6.5 feet (1.5 to 2 meters) away from any interfering sources such as computer
monitors or TV sets.
2. Avoid positioning the Weather Center onto or in the immediate proximity of metal
doors or window frames.
3. Using other electrical products such as headphones or speakers operating on the
same signal frequency (915 MHz) may prevent correct signal transmission and
reception.
Neighbors using electrical devices operating on the 915 MHz signal frequency can

also cause interference.
NOTE:
When the 915 MHz signal is received do not re-open the battery compartment cover of the
transmitter/ rain sensor or Weather station, as the batteries may spring free from the
contacts and force a false reset. Should this happen accidentally then reset all units (see
Set up above) otherwise transmission problems may occur.
During normal operation, after the outdoor display shows "- - -", the weather station will
change to receive the outdoor data every 15 minutes, until the data is read. Then the
reception period for thermo-hygro transmitter will return to 4.5 seconds (6.25 seconds for
rain sensor - optional).
If no reception is possible despite the observation of these factors, all system units have to
be reset (see Set up).
