LCD SCREEN DESCRIPTIONS 

The radio-controlled clock's LCD is divided into 2 sections and once the batteries are inserted, 
all the segments will light up briefly before displaying the information for time, date, indoor and 
outdoor temperatures. 

 
 
 
 
 
 
 
 
 

 

 
WEATHER FORECAST

 

The weather forecasting feature is estimated to be 75% accurate. The weather forecast is 
based solely upon the change of air pressure over time. The WS-8157U averages past air-
pressure readings to provide an accurate forecast, creating a necessity to disregard all weather 
forecasting for 12-24 hours after the unit has been set-up, reset, or moved from one altitude to 
another (i.e. from one floor of a building to another floor).  In areas where the weather is not 
affected by the change of air pressure, this feature will be less accurate. 

 

Weather Icons 

There are 3 possible weather icons that will be displayed in the LCD 2:
