USER’S MANUAL

INTRODUCTION

Congratulations on your purchase of the BAR888 Weather Forecast 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 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.

BEFORE YOU BEGIN

For best operation,

1. Assign different channels to different remote units.

2. Insert batteries for remote units before doing so for the main unit.

3. Place the main unit as close as possible next to the remote unit, reset the main unit after installing batteries. This will ensure easier synchronization between the transmission and reception of signals.

4. Position the remote unit and main unit within effective transmission range, which, in usual circumstances, is 20 to 30 meters.

Note that the effective range is vastly affected by the building materials and where the main and remote units are positioned.

Try various set-ups for best result.

Though the remote units are weather proof, they should be placed away from direct sunlight, rain or snow.

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.

Repeat this step whenever you find discrepancies between the reading shown on the main unit and that on the respective remote unit.

HOW TO CHECK REMOTE AND

INDOORS TEMPERATURES

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

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.

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

MEMORY simultaneously to enforce an immediate search. Of course 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.

Arrow indicator

Rising Steady Falling

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.

6

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.

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.

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. Press MEMORY 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.

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.

7

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.

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:

Indicator displays on the unit

Forecast Sunny Slightly Cloudy Cloudy Rainy

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.

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.
