ABOUT THE OUTDOOR TRANSMITTER
The range of the Thermo-hygro transmitter may be affected by the
temperature. At cold temperatures the transmitting distance may be
decreased. Please bear this in mind when positioning the transmitters. Also
the batteries may be reduced in power for the Thermo-hygro transmitter.
CHECKING FOR 915MHz RECEPTION
If the outdoor temperature and humidity data are not being received within
three minutes after setting up (or outdoor display always show "- -. -" in the
outdoor section of the Weather station during normal operation), please
check the following points:
1.
The distance of the Weather station or transmitters should be at least
6 feet (2 meters) away from any interfering sources such as computer
monitors or TV sets.
2.
Avoid placing the transmitters onto or in the immediate proximity of
metal window frames.
3.
Using other electrical products such as headphones or speakers
operating on the 915MHz-signal frequency may prevent correct signal
transmission or reception. Neighbors using electrical devices
operating on the 915MHz-signal frequency can also cause
interference.
Note:
When the 915MHz signal is received correctly, do not re-open the battery
cover of either the transmitter 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 "Setting up" above) otherwise
transmission problems may occur.
The transmission range is around 330 feet (100 meters) from the Thermo-
hygro transmitter to the Weather station (in open space). However, this
depends on the surrounding environment and interference levels. If no
reception is possible despite the observation of these factors, all system
units have to be reset (see "Setting up" above).
