SETTING UP:
Note: This weather station receives only one outdoor transmitter.
1.
First, insert the batteries into the temperature transmitter. (see “Install and replace
batteries in the temperature transmitter“).
2.
Within 30 seconds, insert the batteries into weather station (see “Install and replace
batteries in the weather station”). Once the batteries are in place, all segments of
the LCD will light up briefly. Then the time (default 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 60 seconds before reinserting them.
3.
After inserting the batteries, the weather station will start receiving data from the
transmitter. The outdoor temperature and the signal reception 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.
4.
In order to ensure successful 868 MHz transmission, this should under good conditions
be a distance no more than 100 meters between the final position of the weather
station and the transmitter (see notes on “Mounting” and “868 MHz Reception”).
5.
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 conditions.
34
Note:
Daily DCF reception is done at 02:00 and 03:00 am every day. If the reception at 03:00 am is
not successful, then at 04:00 and 05:00 and 06:00 am there are other tries, until one is
successful. If the reception at 06:00 am is still not successful, then the next try takes place at
02:00 am next day.
If reception is successful, the received time will override the manually set time. (Please also
refer 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:
1.
Lift up the battery compartment cover.
2.
Insert batteries observing the correct polarity (see
marking).
3.
Replace compartment cover.
35
HOW TO INSTALL AND REPLACE BATTERIES IN THE TEMPERATURE TRANSMITTER
The Temperature Transmitter uses 2 x AAA, IEC LR3, 1.5V batteries. To install and replace
the batteries, please follow the steps below:
1.
2.
3.
Remove the battery compartment cover at the back of the
transmitter.
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.
BATTERY CHANGE:
It is recommended to replace the batteries in all units regularly to ensure
optimum accuracy of these units (Battery life see “Specifications”).
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.
40
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:
•
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 top section of LCD which can be displayed in any of the
following combinations:
45
Sunny
Cloudy with sunny
intervals
Rainy
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 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.
46
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 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
47
that the air-pressure is increasing and the weather is expected to improve, but when indicator
points downwards, the air-pressure 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.
INDOOR MIN/MAX TEMPERATURE RECORDS

LOW BATTERY INDICATOR
Low battery indicator is displayed on the LCD when the batteries require changing.
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 monitors or TV sets.
2.
Avoid positioning the weather station onto or in the immediate proximity of metal
window frames.
3.
Using other electrical products such as headphones or speakers operating on the
same signal frequency (868MHz) may prevent correct signal transmission and
reception.
4.
Neighbors using electrical devices operating on the 868MHz signal frequency can also
cause interference.
50
Note:
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 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 value 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.
Remove the stand from the weather station by pulling it away from
the base and hang the station onto the screw. Remember to ensure
51
that it locks into place before releasing.
Free standing
With the detachable stand, the weather station can be placed onto any flat
surface.
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.
52
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.
•
Precautions shall be taken when handling the batteries. Injuries, burns, or property
damage may be resulted if the batteries are in contact with conducting materials, heat,
corrosive materials or explosives. The batteries shall be taken out from the unit before
