signals
• Shower proof casing
• Wall mounting and table-standing
SETTING UP:
Note: T is weat er station receives only one outdoor transmitter.
1 First, insert the batteries into the Temperature transmitter (see “Install
and replace batteries in t e Temperature transmitter“)
2 Within 30 seconds, insert the batteries into Weather station (see “Install
and replace batteries in t e Weat er station”) Once the batteries are
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
3 After inserting the batteries, the Weather station will start receiving data
from the transmitter The outdoor temperature and the signal reception

27
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 sufficient 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
Note:
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:

28
1 Lift up the battery compartment
cover
2 Insert batteries observing the
correct polarity (see marking)

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 Insert the batteries, observing the correct polarity (see
marking)
3 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

29
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 t e preservation of t e environment.
Return used batteries to an aut orised 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:

30
• 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:
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

Clo
udy wit

36
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

37
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 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

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
3 Neighbours using electrical devices operating on the 868MHz signal
frequency can also cause interference
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

40
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

41
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
