NOTE:  
HOW TO USE AND SCAN  
THE MOON PHASE  
1. The accuracy of a general pressure-based weather forecast is  
about 70 to 75%, and therefore, cannot be held responsible for  
any inconveniences so caused by an inaccurate forecast.  
The BAR928 is equipped with a moon phase display and scanner  
with which eight moon phases are displayed on the screen from new  
moon to waning crescent. The one falls on the current day will flash  
on the screen.  
2. The weather forecast is meant for the next 12 to 24 hours. It may  
not necessarily reflect the current situation.  
3. The “Sunny” icon, when applies to night time, implies clear  
weather.  
If it is a full moon or new moon day, the icon will flash faster.  
The eight phases are:  
INDOOR RELATIVE HUMIDITY  
The indoor relative humidity is automatically detected. The reading  
is displayed in the relative humidity window.  
Like temperature, the maximum and minimum relative humidity  
will be stored in memory. Use the MEMORY button to rotate  
through the maximum, minimum and current relative humidity. The  
respective MAX and MIN indicator will be displayed.  
New Moon  
Waning Crescent  
Last Quarter  
Waxing Crescent  
First Quarter  
Waning Gibbous  
Full Moon  
To clear the memory, hold down MEMORY for three seconds. The  
maximum and minimum temperatures will be erased. If you press  
MEMORY now, the maximum and minimum relative humidity will  
have the same values as the current one until different readings are  
recorded.  
Waxing Gibbous  
To check the moon phase for a particular day, press the UP or  
DOWN button once. The clock will enter moon phase scanning  
mode.  
Use the UP or DOWN button to locate the date you want to check.  
The calendar will be day-driven in this mode.  
COMFORT LEVEL  
You can go back in time or travel to the future, any day between the  
years 1990 to 2089. The corresponding moon phase will appear  
immediately on the screen.  
The comfort level is based on the recorded relative humidity. An  
indicator will be displayed to show if the level is comfortable, wet or  
dry.  
The unit will return to the last display mode when the UP and  
DOWN buttons are left idle for 15 seconds.  
HOW TO WALL MOUNT OR USE
