LOW BATTERY INDICATOR

Low battery indicator is displayed on the LCD when the batteries require changing.

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).
