HEAT INDEX & DEW POINT EXPLAINED
Heat Index:
Heat Index combines the eects of heat and humidity. It is the apparent temperature of how hot it feels to a
human being. As humidity increases, the body is unable to cool eectively. The temperature will feel
warmer.
Dew Point:
Dew Point Temperature is the saturation point of the air, or the temperature to which the air has to cool in
order to create condensation. The higher the dew points, the higher the moisture content of the air at a
given temperature.

• Hold the TEMP button for 3 seconds to search for the sensor. Sensor Reception icon will flash while
searching and be solid when sensor signal is received.
• If you regain connection while the sensor is mounted, great. If you do not regain connection, bring the
sensor within 10 feet of the station and search again.
Note:
• If the signal is lost, the RX will display the ast data recorded from sensor for 10 minutes.
• After that 10 minutes if the signal does not come back then you will see dashes “--”.
• After 30 minutes, start looking for the sensor signal automatically.
The unit predicts weather condition of the next 12-hours based on the change of atmospheric pressure. The
weather forecast is about 70-75% correct.
