SETTING UP:

Note: This weather station receives only one outdoor transmitter.

1. First, insert the batteries into the Temperature transmitter. (see “ and replace batteries in the Temperature transmitter “).

Install

2. Within 30 seconds, insert the batteries into Weather station (see “I nstall and replace batteries in the Weather station ”). Once the batteries are

3. in place, all segments of the LCD will light up briefly. Then the time (as

0:00) and the weather icon will be displayed. If these are not displayed after 60 seconds, remove the batteries and wait for at least 30 seconds before reinserting them.

After inserting the batteries, the Weather station will start receiving data from the transmitter. The outdoor temperature and the signal reception

26

4. icon should then be displayed on the Weather station. If this does not happen after 3 minutes, the batteries will need to be removed from both units and reset from step 1.

In order to ensure sufficient 868 MHz transmission, this should under good conditions be a distance no more than 100 meters between the

5. final position of the Weather Station and the transmitter (see notes on

“ Mounting ” and “ 868 MHz Reception ”).

Once the remote temperature has been received and displayed on the

Weather station, the DCF time (radio controlled time) code reception is automatically started. This takes typically between 3-5 minutes in good

Note: conditions.

Daily DCF reception is done at 02:00 and 03:00 every day. If the reception at

03:00 is not successful, then at 04:00 and 05:00 and 06:00 there are other tries, until one is successful. If the reception at 06:00 is still not successful, then the next try takes place at 02:00 next day.

If reception is successful, the received time will override the manually set time.

(Please refer also to notes on “ DCF-77 Radio Controlled Time ” and “ Manual

Time Setting ”).

HOW TO INSTALL AND REPLACE BATTERIES IN THE WEATHER

STATION

The Weather Station uses 2 x AA, IEC LR6, 1.5V batteries. When batteries need to be replaced, the low battery icon will appear on the LCD. To install and replace the batteries, please follow the steps below:

27

1.

2.

Lift up the battery compartment cover.

Insert batteries observing the correct polarity (see marking).

3. Replace compartment cover.

HOW TO INSTALL AND REPLACE BATTERIES IN THE

TEMPERATURE TRANSMITTER

The Temperature Transmitter uses 2 x AAA, IEC LR3, 1.5V battery. To install and replace the batteries, please follow the steps below:

1. Remove the battery compartment cover at the back of the transmitter.

2.

3.

Insert the batteries, observing the correct polarity (see marking).

Replace the battery compartment cover on the unit.

Note:

In the event of changing batteries in any of the units, all units need to be reset by following the setting up procedures. This is because a security code is assigned by the transmitter at start-up and this code must be received and stored by the Weather station in the first 3 minutes of power being supplied to it.

28

BATTERY CHANGE:

It is recommended to replace the batteries in all units regularly to ensure optimum accuracy of these units (Battery life See

Specifications below).

Please participate in the preservation of the environment.

Return used batteries to an authorised depot.

DCF-77 RADIO CONTROLLED TIME

The time base for the radio-controlled time is a Cesium Atomic Clock operated by the Physikalisch Technische Bundesanstalt Braunschweig which has a time deviation of less than one second in one million years. The time is coded and transmitted from Mainflingen near Frankfurt via frequency signal DCF-77

(77.5 kHz) and has a transmitting range of approximately 1500 km. Your radio-controlled Weather Station receives this signal and converts it to show the precise time in summer or wintertime.

The quality of the reception depends greatly on the geographic location. In normal cases, there should be no reception problems within a 1500km radius of Frankfurt.

After the outdoor transmitter reception is completed in initial setup, the DCF tower icon on the clock display will start flashing. This indicates that the clock has detected that there is a radio signal present and is trying to receive it.

When the time code is received, the DCF tower becomes permanently lit and the time will be displayed.

If the tower icon flashes, but does not set the time or the DCF tower does not appear at all, then please take note of the following:

29

•

•

Recommended distance to any interfering sources like computer monitors or TV sets is a minimum of 1.5 - 2 meters.

Within ferro-concrete rooms (basements, superstructures), the received signal is naturally weakened. In extreme cases, please place the unit close to a window and/ or point its front or back towards the Frankfurt

• transmitter.

During nighttime, the atmospheric disturbances are usually less severe and reception is possible in most cases. A single daily reception is adequate to keep the accuracy deviation below 1 second.

WEATHER FORECAST AND TENDENCY

THE WEATHER FORECASTING ICONS:

There are 3 weather icons in the second section of LCD which can be displayed in any of the following combinations:

Sunny Cloudy with Rainy sunny intervals

For every sudden or significant change in the air pressure, the weather icons will update accordingly to represent the change in weather. If the icons do not

35

change, then it means either the air pressure has not changed or the change has been too slow for the Weather station to register. However, if the icon displayed is a sun or raining cloud, there will be no change of icon if the weather gets any better (with sunny icon) or worse (with rainy icon) since the icons are already at their extremes.

The icons display weather forecasts in terms of getting better or worse, and not necessarily sunny or rainy as each icon indicates. For example, if the current weather is cloudy and the rainy icon is displayed, it does not mean that the product is faulty because it is not raining. It simply means that the air pressure has dropped and the weather is expected to get worse but not necessarily rainy.

Note:

After setting up, readings for weather forecasts should be disregarded for the next 12-24 hours. This will allow sufficient time for the Weather Station to collect air pressure data at a constant altitude and therefore result in a more accurate forecast.

Common to weather forecasting, absolute accuracy cannot be guaranteed.

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 for use in. In areas that experience sudden changes in weather (for example from sunny to rain), the Weather Station will be more accurate compared to use in areas where the weather is stagnant most of the time (for example mostly sunny).

If the Weather Station is moved to another location significantly higher or lower than its initial standing point (for example from the ground floor to the

36

upper floors of a house), remove the batteries and re-insert them after about

30 seconds. By doing this, the Weather Station will not mistake the new location as being a possible change in air-pressure when really it is due to the slight change of altitude. Again, disregard weather forecasts for the next 12 to

24 hours as this will allow time for operation at a constant altitude.

THE WEATHER TENDENCY INDICATOR

Working together with the weather icons are the weather tendency indicators

(located on the left and right hand side of the weather icons). When the indicator points upwards, it means that the air-pressure is increasing and the weather is expected to improve, but when indicator points downwards, the airpressure is dropping and the weather is expected to become worse.

Taking this into account, you will see how the weather has changed and how it is expected to change. For example, if the indicator is pointing downwards together with cloud and sun icons, then the last noticeable change in the weather was when it was sunny (sun icon only). Therefore, the next change in the weather will be the cloud with rain icons since the indicator is pointing downwards.

Note:

Once the weather tendency indicator has registered a change in the air pressure, it will remain permanently visualized on the LCD.

868 MHz RECEPTION CHECK

The Weather station should receive the temperature data within 3 minutes after set-up.

If the temperature data is not received 3 minutes after setting up

(not successfully continuously, the outdoor display shows “- - -” ), please check the following points:

1. The distance of the Weather station or transmitter should be at least 1.5 to 2 meters away from any interfering sources such as computer

2. monitors or TV sets.

Avoid positioning the Weather station onto or in the immediate proximity

3. of metal window frames.

Using other electrical products such as headphones or speakers operating on the same signal frequency (868MHz) may prevent correct signal transmission and reception.

Neighbours using electrical devices operating on the 868MHz signal 3.

Note: frequency can also cause interference.

When the 868MHz signal is received correctly, do not re-open the battery cover of either the transmitter or Weather station, as the batteries may spring free from the contacts and force a false reset. Should this happen accidentally then reset all units (see Setting up above) otherwise transmission problems

39

may occur.

The transmission range is about 100 m from the transmitter to the Weather station (in open space). However, this depends on the surrounding environment and interference levels. If no reception is possible despite the observation of these factors, all system units have to be reset (see Setting up ).

POSITIONING THE WEATHER STATION:

The Weather Station may be hung onto wall easily or free standing.

To wall mount

Choose a sheltered place. Avoid direct rain and sunshine.

Before wall mounting, please check that the outdoor temperature values can be received from the desired locations.

1 Fix a screw (not supplied) into the desired wall, leaving the head extended out by about 5mm.

2 Hang the station onto the screw.

Remember to ensure that it locks into place before releasing.

Free standing

With the foldout stand, the weather station can be placed onto any flat surface.

40

POSITIONING THE TEMPERATURE TRANSMITTER:

The Transmitter is supplied with a holder that may be attached to a wall with the two screws supplied. The Transmitter can also be position on a flat surface by securing the stand to the bottom of the Transmitter.

To wall mount:

1. Secure the bracket onto a desired wall using the screws and plastic anchors.

2. Clip the remote temperature sensor onto the bracket.

Note:

Before permanently fixing the transmitter wall base, place all units in the desired locations to check that the outdoor temperature reading is receivable. In event that the signal is not received, relocate the transmitter or move the units slightly as this may help the signal reception.

CARE AND MAINTENANCE:

• Extreme temperatures, vibration and shock should be avoided as these may cause damage to the unit and give inaccurate forecasts and readings.
