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

transmittedbytheremoteunit.Themainunitcansupportuptothree

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.

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).

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.

HOW TO CHECK REMOTE AND

INDOORS TEMPERATURES

The indoors temperature is shown on the 3rd line of the display.

Asfortheremotesitesorchannels,pressCHANNELtogofromone

channelto another.The kineticwave display onthe channelnumber

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 todisplay themaximum 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

goesblank,pressCHANNELandMEMORYtoenforceanimmedi-

ate 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 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.

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 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:

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)

When the reception is complete, the radio reception signal will

stop blinking. The strength of the reception for the last full hour

will be indicated.

For better reception, place the clock away from metal objects and

electrical appliances to minimize interference.

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.

To enable the feature again, press the ( ) button for three

seconds. The radio reception signal will start blinking to initiate

reception automatically.

MODE 3. Hour-Minute-Day of the Week (of local time)

Hour-Minute (of second time zone)

MODE 4. Hour-Minute-Day of the Week (of second time zone)

Day-Month (of second time zone)

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 BAR888 is designed to automatically synchronize its clock

once it is brought within range of the Frankfurt DCF77 radio

signal.

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.

-Strong

-Weak

-No singal

-Receiving

HOW TO SET THE CLOCK MANUALLY

To set the clock manually, hold MODE/SET for three seconds. The

display will return to MODE 1, with the hour digits blinking.

Use ( ) or ( ) to select the hour. Press and hold to increase

or decrease the value rapidly.

Press MODE/SET to confirm. The minute digits will blink. Repeat

the same procedure to set the minutes, then the day-of-month,

month, display language, day-of-week and offset for the second

time zone.

Note: The time and date are displayed in 24-hour clock and DAY-

MONTH format. For the language display, you can choose among

English (E), German (D), French (F) and Italian (I). Day-of-week is

the usual sequence of Monday through Sunday.

For the second time zone, which is indicated by the ZONE ICON,

enter the hour offset using the UP and DOWN buttons and the

BAR888 will calculate the second time accordingly.

If there is an item you do not wish to change, simply press MODE/

SET to bypass the item.

When you are done, press MODE/SET to exit. The display will

return to the mode last chosen.
