The unit predicts weather condition of the next 12 

– 24 hours based on the change of atmospheric 

pressure.  The weather forecast is based on atmospheric pressure change and is about 70-75% correct.  
As weather conditions cannot be 100% correctly forecasted we cannot be responsible for any loss 
caused by an incorrect forecast. 

 

NOTE: Different geographical location such as inland area or coastal region has different weather 
forecasting response. In case the wireless display shows the wrong weather forecast over a long period 
and does not reflect the actual weather condition, it is necessary to adjust the weather forecast to the 
current weather condition in the SETUP menu. Allow 48 hours for the wireless display to adjust to your 
environment when first setup. 
 
Often it is easiest to wait for a rainy day then enter the SETUP menu and select WEATHER FORECAST 
then RAINY. Select ENTER and then exit.  
 
 

The LCD shows the relative air pressure value and the air pressure history on a bar graph. The bar graph 
is available in Weather Mode. Reading the graph from left to right you can easily see if pressure has been 
rising or falling. 
 
The vertical bars are plotted at each of the five steps to give the trend over the past six hours. The 0-hour 
vertical bar will always display at the midline height to indicate the current air pressure. The varying 
heights of bars in other columns on the graph indicate a relative change in air pressure up or down from 
the previous measurement. 
 
 
 
 
 

 
NOTE: The bar graph will scroll right to left regularly to prevent LCD burnout.
