

digital stations measure not only the time in progress – thanks to their built-in clock- but also

the actual and upcoming weather.

The MeteoClock

SM1840 incorporates the following functions:

- Thermometer:

The temperature is displayed in real time to the nearest tenth of a degree Celsius. Thanks to its

wireless sensor, the weather station can give you the temperature reading outside or in another room.

- Hygrometer:

Outdoor or indoor hygrometry is expressed in percentage of humidity in the ambient air. The ideal

‘Comfort Zone’ for the human body ranges from 35 to 65% hygrometry for a given temperature

between 18 and 24

- Barometer:

The station also monitors the atmospheric pressure and, based on its pattern of evolution, displays a

weather forecast as a user-friendly icon: sun, clouds, rain... That’s the weather to be expected in the

next 8 to 12 hours.

And many extra features:

- Animated icons - Wall mounting stand

- Pivoting and rotating base - Blue backlit LCD display

sensors please refer to the section ACCESSORIES at the end of this manual. SM1842 comes with

2 sensors, SM1843 comes with 3 sensor.

SYNCHRONIZA

TION

1. The Learn function executes automatically and runs for approximately 2 minutes when the batteries

are first installed in the receiver.

2. Within these 2 minutes, the main unit picks up the temperature & humidity signals from the remote

sensor and displays the readings. If you only have one remote sensor, the main unit will be

automatically synchronized with the channel set on the remote sensor.

Radio Controlled Clock:

1. The SM1840 is designed to automatically synchronize its calendar clock once it is brought within a

range of 1500km of the Frankfurt DCF77 radio signal. When the SM1840 is brought within this range,

its auto-control mechanism will override all manual settings.

2. The clock automatically starts scanning the RF 433MHz signal after new batteries are inserted in the

main unit. When receiving the RF 433MHz radio signal, the Radio Tower symbol “ ”starts to blink

[A20]. A complete reception generally takes about 10 minutes, depending on the strength of the

radio signal.

3. When the reception is complete, the Radio Tower symbol “ ” will stop blinking and remain solid.

4. For an optimal reception, place the clock away from metal objects and electrical appliances

(i.e. television, computer, monitor, etc.) to minimize interference.

Notes:

- For a better reception and synchronization, please first place the main unit near a window on a table

or on a shelf.

- Most of the buttons will not function during the scan and will work again once the DCF signal is well

received or the scan is stopped manually.

- The clock automatically scans the time signal at 3.00 a.m. everyday to maintain accurate timing. If the

reception fails, the scan is interrupted and the unit will try to a new scan at 4:00am, 5:00am and

6:00am.

- If the reception fails or the unit is out of auto-clock range, the scan stops and “ ” disappears from

the LCD screen.

- Y

ou can trigger the radio clock synchronization by holding the [B11] button for 3 seconds.

Press and hold the [B11] button again to stop the DCF signal scan.

FIXING THE REMOTE SENSOR AND MAIN UNIT

Remote sensor

The remote sensor can be placed upright on a smooth surface or

wall-mounted. To ensure a good transmission, the remote sensor

should not be installed on or near a large metal surface. Before

choosing the location of the remote sensor, test that the receiver can

receive the signals. It is also recommended that the remote sensor is

placed as close as possible to the main unit to eliminate any interference. The remote sensor can also

be wall-mounted. To do so, locate the wall-mounting hole at the back of the sensor (upper part) and fix

it on a hook or nail.

Main unit

The main unit can be fixed on the rotating/pivoting base or on the wall-mounted

base (both included). To use the base, fix the main unit’s socket (located under

the unit) into the base’s jack. Place the base on a smooth, stable surface. To use

the wall-mounted base, insert a screw in each wall-mounting hole (2) and fix it

to a wall. Then, fix the main unit’s socket into the wall-mounted base’s jack.

USING THE TEMPERATURE PROBE:

1. It is recommended use the temperature probe to sense the temperature when the

outside temperature is between the range: -50°C ~ 0°C and +50°C~+70°C

2. When the outdoor temperature is below -20 °C, it is mandatory to use the probe

outside and place the sensor unit indoors to avoid freezing the battery

3. To use the probe, insert the probe plug on the bottom right hand side of the remote sensor.

Animated Weather Forecast Symbols

This weather station is capable of detecting barometric pressure changes, and based on the data

collected, predicting the weather for the next 8 to 12 hours. There are 5 different weather forecast

symbols [A1].

Note:

The remote sensor set on Channel 1 is used to help displaying the weather forecast icons

(as well as the trend indicator). Please place it outdoors.

REMARKS:

 After having completed the settings of your weather station, please discard the readings of the

weather forecast for the next 12-24 hours. This will allow sufficient time for the Weather Station to

operate at a constant altitude and therefore result in a more accurate forecast.

 Absolute accuracy cannot be guaranteed regarding weather forecasting.

 The weather forecasting feature is estimated to have an accuracy level of about 75% due to the

varying areas the Weather Station has been designed to be used in.

Barometric Pressure Meter

The barometric pressure [A4] can be measured in 3 different units: inHg (inches of mercury), mb

(millibar) and hPa (hecto-Pascal). Inches of mercury are employed in the United States. Millibars and

hecto-Pascal are equivalent. You can select the barometric pressure to be displayed in nHg or in mb /

hPa.

To toggle between the two measurements, press and hold the [B7] key.

Why study barometric pressure?

Generally, bad weather is associated with low barometric pressure and fine

weather with high pressure. A low pressure area is surrounded by air of

higher pressure. As the higher pressure air cannot move in the low pressure

area, it will move upwards, causing condensation of water in the air and

producing clouds. The opposite is true for high pressure: in a high pressure

area, air of lower pressure will move downwards, warming up the air and

evaporating the water in the air.

Pressure trend

The trend pointer displayed at [A2] indicates the trend of the barometric pressure.

Indicates that the barometric pressure trend is increasing.

Indicates that the barometric pressure trend is steady.

Indicates the barometric pressure trend is decreasing.

Low pressure

Barometric pressure historical graph

The bar graph [A15] lets you see the pressure trend over the past 12 hours. The weather forecast,

by the means of the animated icons [A1], depends on the evolution of the barometric pressure. By

consulting the barometric pressure historical graph you can evaluate the likeliness or the strength of the

weather forecast currently displayed. For example, if the pressure has steadily increased over the past

12 hours but decreases slightly in the next 3 hours, the weather station might forecast rain, but you

could expect the probability of rain to remain low. On the other hand, if you observe a sudden and large

shift in pressure, the weather forecast is more likely to be extreme. For example, if the forecast is rain,

and you observe a large and sudden downward shift of pressure, the rain is likely to be heavy.

The left column displays the change in inches of mercury and

the right column in hecto-Pascal. The bottom row indicates

the time (hr = hour).

To retrieve past barometric pressure readings (up to 12 hours

ago), press the [B6] key. The hour will be displayed at [A3].

The example below shows the barometric pressure reading 12 hours ago.

°C or °F Temperature display:

You can select to display the indoor temperature [A5] in Celsius (°C) or Fahrenheit (°F) by pressing the

[B8] key. For the outdoor temperature [A8], press [B11] to toggle between °C and °F.

TEMPERATURE DISPLAY AND ALARM

Outdoor Temperature Alert Function:

1. Press and hold the [B9] button to set the outdoor temperature alert function.

2. Use the [B10] and [B11] keys to select the channel of the temperature alert. If you only have one

remote sensor, then the channel is 1.

3. Press [B9] to confirm.

4. Use the [B10] and [B11] keys to set the upper limit of the temperature alarm “▲” and press [B9]

to confirm.

5. Use the [B10] and [B11] keys to set the lower limit “▼” of the temperature alarm and press [B9]

to confirm.

6. For example, you can set the temperature alarm between 0°C and 35°C. Every time the remote

sensor registers an outdoor temperature lower than 1°C or higher than 34°C, the temperature alarm

will ring and [A8] will blink. It will ring for a few seconds, stop, and ring a few seconds later until it is

turned off.

7. When the temperature alarm is turned on, the ▲ symbol will appear at [A5] and the ▼ symbol at

[A8]. Press [B9] to turn the temperature alarm on and off.

MAXIMUM/MINIMUM TEMPERATURE/HUMIDITY RECORDING FUNCTION

Moon phases

Throughout the 28 days of the lunar month, the aspect of the moon changes. Indeed, the moon,

being spherical, is always half lightened up by the sun. As the moon rotates around the Earth, the

appearance of its lightened side changes continuously. This phenomenon creates moon phases. The

moon phase [A17] on your MeteoClock

is automatically updated according to the year / month / day.

1: New Moon 2: Young Crescent 3: First Quarter 4: Waxing Gibbous

5: Full Moon 6: Waning Gibbous 7: Last Quarter 8: Waning Crescent

Tides

Every 12 hours approximately, the oceans on each side of the planet rise slightly then fall back. This

movement is called tides. It is the result of the gravitational pull of the moon and the sun and the

rotations of the earth, moon and sun. Your weather station displays the tide status [A17] as follows:

H: High Tide M: Medium Tide L: Low Tide

If you have one or two additional sensors, you can place them in a different location in your house; in

a bedroom, for example. Your main unit can collect the temperature and humidity data of up to three

remote sensors.

FURTHER INSTRUCTIONS FOR MULTI-SENSOR USE

MOON PHASES & TIDES

Set up:

To set up a new sensor, follow the instructions given on page 5. Make sure you set every sensor to a

different channel.

Temperature and humidity and display :

You can view the humidity and temperature readings of your different remote sensors by pressing the

[B2] key. The sequence is as follows:

The sign ‘ ’ [A12] means that the unit will display your available channels alternatively.
