USER’S MANUAL
INTRODUCTION
Congratulations on your purchase of the BAR888A 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 barometer,
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 BAR888A operates at 433MHz, it can be used
in the U.S. and most places in Continental Europe.
It automatically synchronizes its current time and date when it is
brought within range of the radio signal from U.S. Atomic Clock.
You can also set the calendar clock manually when it is off range.
Other features include four-language display, four-step crescendo
dual alarms and interchangeable display modes.

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.
GETTING STARTED
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 signals are received, blanks “ ” will be displayed and
the kinetic wave icon will show “ ”. Press CHANNEL and
MEMORY simultaneously to enforce another search for about 30
seconds. This is useful in synchronizing the transmission and
reception of the remote and main units.
Repeatthisstepwheneveryoufinddiscrepanciesbetweenthereading

HOW TO CHECK REMOTE AND
INDOORS TEMPERATURES
The indoors temperature is shown on the 3rd line of the display.

indicates the reception of that particular channel is in good order.
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.
If the temperature goes above or below the temperature measuring
range of the main unit or the remote unit (stated in specification) ,
the display will show “HHH” or “LLL”.

HOW TO READ THE KINETIC
WAVE DISPLAY
The kinetic wave display shows the signal receiving status of the
main unit. There are three possible forms:
The unit is in searching mode.
Temperature readings are securely
registered.
No signals.
MAXIMUM AND MINIMUM
TEMPERATURES
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. PressMEMORY once to display the maximum temperature and
again the minimum temperature. The respective indicators,
MAX or MIN will be displayed.
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.
DISCONNECTED SIGNALS
If without obvious reasons the display for a particular channel
goes blank, press CHANNEL and MEMORY to enforce an
immediate search. If that fails, check:
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.
Note: When the temperature falls below freezing point, the
batteries of outdoor units will freeze, lowering their voltage
supply and the effective range.
3. The transmission is within range and path is clear of obstacles
and interference. Shorten the distance when necessary.
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.
NOTE ON °C AND °F
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
Your BAR888A 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.
Important:
1. The accuracy of weather forecasting when using pressure
trend alone is about 70 to 75 percent and, therefore, the
manfuacturers and suppliers cannot be held responsible for
any inconveniences caused by an inaccurate weather fore
cast.
2. The weather forecast symbols may not reflect current weather
condition. The symbols are forecasting the future.
3. A “SUNNY” forecast covering the night-time reflects fine clear
weather.
HOW TO READ THE PRESSURE TREND
The BAR888A 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:
CALENDAR CLOCK DISPLAY MODES
The BAR888 supports four display modes in the sequence of:
MODE 1. Hour-Minute-Second (of local time)
Day-Month (of local time)
MODE 2. Hour-Minute-Day of the Week (of local time)
Day-Month (of local time)

Press MODE, to change from one display mode to the next
Note: The bottom line of the display will be replaced by the alarm
time if the [24hr OFF] button is pressed.
ABOUT RADIO RECEPTION
The BAR888A is designed to automatically synchronize its current
time and date when it is brought within range of the radio signal
fromU.S.Atomic Clock.
When the BAR888 is within range, its radio-control mechanism
will override all manual settings.
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.
