USER’S MANUAL  
INTRODUCTION  
Congratulations on your purchase of the BAR888 Weather Fore-  
cast Multi-Channel In-Out Thermometer with 433MHz cable  
free sensor and radio-controlled calendar clock.  
The basic package comes with a main unit (which is the barom-  
eter, temperature and calendar clock station), and a remote unit  
(the thermo sensor).  
The main unit has large read-outs for weather forecast, indoors  
temperature, calendar clock and temperatures collected and  
transmitted by the remote unit. The main unit can support up to three  
remote units.  
The main unit is capable of keeping track of the maximum and  
minimum temperature of different sites. And no wire installation is  
required. As the BAR888 operates at 433MHz, it can be used in the  
U.S. and most places in Continental Europe.  
FRONT VIEW  
As for the calendar clock, it is radio-controlled. It automatically  
synchronizes its current time and date when it is brought within an  
approximate 1500km radius of the radio signal generated from  
Frankfurt,Germany(DCF77).

THE RESET BUTTON  
This button is only used when the unit is operating in an  
unfavorable way or malfunctioning. Use a blunt stylus to hold  
down the button. All settings will return to their default values.  
HOW TO CHECK REMOTE AND  
INDOORS TEMPERATURES  
The indoors temperature is shown on the 3rd line of the display.  
GETTING STARTED  
As for the remote sites or channels, press CHANNEL to go from one  
channel to another. The kinetic wave display on the channel number  
indicates the reception of that particular channel is in good order.  
Once batteries are in place for the remote units, they will start  
transmitting temperature readings at 30-second intervals.  
The main unit will also start searching for signals for about a  
minute once batteries are installed. Upon successful reception, the  
individual channel temperatures will be displayed on the 2nd line  
and the indoors temperature on the 3rd line. The main unit will  
automatically update its readings at about 30-second intervals.  
If no readings are received from one particular channel for more  
than two minutes, blanks “  
” will be displayed until further  
readings are successfully searched. Check the remote unit is sound  
and secure. You can wait for a little while or press CHANNEL and  
MEMORYsimultaneouslytoenforceanimmediatesearch.Ofcourse  
no reading will be shown if no remote unit is assigned to that  
channel.  
The temperature trend indicator on the screen shows the trend of  
samplings collected at that particular remote site. Three trends,  
rising, steady and falling, will be shown.

HOW TO READ THE KINETIC  
WAVE DISPLAY  
DISCONNECTED SIGNALS  
If without obvious reasons the display for a particular channel  
goesblank, pressCHANNELandMEMORYtoenforceanimmedi-  
ate search. If that fails, check:  
The kinetic wave display shows the signal receiving status of the  
main unit. There are three possible forms:  
1. The remote unit of that channel is still in place.  
2. The batteries of both the remote unit and main unit. Replace as  
necessary.  
The unit is in searching mode.  
Temperature readings are securely  
registered.  
Note: When the temperature falls below freezing point, the  
batteries of outdoor units will freeze, lowering their voltage  
supply and the effective range.  
No signals.  
3. The transmission is within range and path is clear of obstacles  
and interference. Shorten the distance when necessary.  
MAXIMUM AND MINIMUM  
TEMPERATURES  
TRANSMISSION COLLISION  
Signals from other household devices, such as door bells, home  
security systems and entry controls, may interfere with those of  
this product and cause temporarily reception failure. This is normal  
and does not affect the general performance of the product. The  
transmission and reception of temperature readings will resume  
once the interference recedes.  
The maximum and minimum recorded indoor temperatures and  
those of each channel will be automatically stored in memory. To  
display them,  
1. Select the channel to be checked.  
2. Press MEMORY once to display the maximum temperature and  
again the minimum temperature. The respective indicators,  
MAX or MIN will be displayed.  
NOTE ON °C AND °F  
To clear the memory, hold down MEMORY for two seconds. The  
maximum and minimum temperatures will be erased. If you press  
MEMORY now, the maximum and minimum temperatures will  
have the same values as the current ones until different readings are  
recorded.  
The unit of temperature display is selected on the °C/°F slide  
switch. Select °C for Centigrade or °F for Fahrenheit.  
Note: The remote temperature display shown on the main unit is  
dominated by the selection on the °C/°F slide switch of the main  
unit. Whatever the display units of the remote sensors are, they will  
be automatically converted to the chosen one of the main unit.

WEATHER FORECAST FUNCTION  
HOW TO READ THE PRESSURE TREND  
Your BAR888 detects barometric pressure changes and the LCD  
displays the illustrated weather symbols which indicates the  
weather forecast for 12 to 24 hours ahead, for an area with a radius  
of about 30-50 km.  
The BAR888 gives you the pressure trend for the last hour. It is  
indicated by the arrow displayed in the right hand side of the upper  
display. An upward pointing trend arrow indicates that it is likely  
that the weather is improving or may be getting worse if the trend  
(arrow) is falling. Here is what it can look like:

ABOUT RADIO RECEPTION  
The BAR888 is designed to automatically synchronize its clock  
once it is brought within range of the Frankfurt DCF77 radio  
signal.  
If you wish to disable the auto-reception feature, press the (  
)
button for three seconds. The radio reception signal will disappear.  
The unit will not respond to radio signals.  
When the BAR888 is within range, its radio-control mechanism  
will override all manual settings.  
To enable the feature again, press the (  
) button for three  
seconds. The radio reception signal will start blinking to initiate  
reception automatically.  
When the unit is receiving radio signal, the radio reception signal  
will start to blink. A complete reception generally takes about 2 to  
10 minutes, depending on the strength of the radio signal.
