TO INSTALL AND REPLACE BATTERIES IN THE
WEATHER STATION
The weather station uses 2 x AA, IEC LR6, 1.5V batteries.
To install and replace the batteries, please foll ow the steps
below:
Battery replacement
•
Replace the batteries when the battery symbol of
the weather station appears on the upper display.
•
When the batteries of the transmitter are used up,
the low battery icon appears next to the outdoor
temperature display.
Note:
In the event of changing batteries in any of the units, all
units need to be reset by following the setti ng up
procedures. This is due to a random securi ty code
assigned by the transmitter at start-up. This code must be
received and stored by the weather station i n the first 3
minutes of power being supplied to the transmitter.
1. Insert finger or other
solid object in the
space at the bottom
center of the battery
compartment and lift up
to remove the cover.
2. Insert batteries
observing the correct
polarity (see marking).
3. Replace compartment
cover.
23
SETTING UP
1. First, insert the batteries in the transmitter (see “To
install and replace batteries in the thermo-hygro
transmitter” above).
2. Within 2 minutes of powering up the transmi tter,
insert the batteries in the weather station (see “To
install and replace batteries in the weather
station” above). Once the batteries are in pl ace, all
segments of the LCD will light up briefly. Following
the indoor temperature/humidity and the time as
00:00 will be displayed. If these information are not
displayed on the LCD after 60 seconds, remove the
batteries and wait for at least 60 seconds before
reinserting them. Once the indoor data is di splayed
user may proceed to the next step.
3. After the batteries are inserted, the weather station
will start receiving data signal from the transmitter.
The outdoor temperature and humidity data sho uld
then be displayed on the weather station. If this
does not happen after 2 minutes, the batteri es will
need to be removed from both units and reset from
step 1.
4. In order to ensure sufficient 868 MHz transmission
however, the distance between the weather stati on
and the transmitter should not be more than 100
meters (see notes on “Positioning” and “868 MHz
Reception”).
Note:
In the event of changing batteries of the units,
ensure the batteries do not spring free from the
contacts. Always wait at least 1 minute after
removing the batteries before reinserting, otherwise
start up and transmission problems may occur.
5. Once the outdoor data reception test period i s
completed, the DCF tower icon in the clock display
will start flashing in the upper left corner. This
indicates that the clock has detected that there is a
radio signal present and is trying to receive i t. When
the time code is received, the DCF tower becomes
permanently lit and the time will be displayed.
24
DCF RADIO CONTROLLED TIME
The time base for the radio controlled time i s a Cesium
Atomic Clock operated by the Physikalisch Technische
Bundesanstalt Braunschweig which has a ti me 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 1,500 km. Your radiocontrolled 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 sho uld be no
reception problems within a 1,500 km radius of Frankfurt.
DCF reception is done twice daily at 02:00 and 03:00 am.
If the reception is not successful at 03:00 am, then the
next reception takes place the next hour and so o n until
06:00am, or until the reception is successful. If the
reception is not successful at 06:00 am, then the next
attempt will take place the next day at 02:00 am.
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 possibl e in most
cases. A single daily reception is adequate to keep
the accuracy deviation below 1 second.

WEATHER FORECAST AND WEATHER
TENDENCY:
WEATHER FORECASTING ICONS:
The weather icons in the second section of LCD can be
displayed in any of the following combinations:
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, t hen it
means either the air pressure has not changed or the
change has been too slow for the weather stati on to
register. However, if the icon displayed is a sun or raining
cloud, there will be no change of icon if the weat her gets

any better (with sunny icon) or worse (with rainy icon)
since the icons are already at their extremes.
The icons displayed forecasts the weather i n terms of
getting better or worse and not necessaril y sunny or rainy
as each icon indicates. For example, if the current weather
is cloudy and the rainy icon is displayed, i t does not mean
that the product is faulty because it is not rai ning. It simply
means that the air pressure has dropped and the weather
is expected to get worse but not necessaril y 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 coll ect 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 forecasti ng feature is
estimated to have an accuracy level of about 75% due to
the varying areas the weather station has bee n designed
for use. In areas that experience sudden changes in
weather (for example from sunny to rain), the weather
station will be more accurate compared to use i n areas
where the weather is stagnant most of the ti me (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), discard the weather forecast for the next 12-24
hours. By doing this, the weather station will not mistake
the new location as being a possible change i n air
pressure when really it is due to the slight change of
altitude.
WEATHER TENDENCY INDICATOR
The weather tendency indicators (located on the left and
right sides of the weather icons) are working together with
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 poi nts
downwards, the air pressure is dropping and the weather
is expected to become worse.
Taking this into account, one can see how the weather has
changed and is expected to change. For example, if the
31
Indoor
temperature
indicator is pointing downwards together wi th cloud and
Outdoor
temperature
in ºC
sun icons, then the last noticeable change in the weather
was when it was sunny (the sun icon only). Therefore, the
next change in the weather will be cloud wi th rain icons
since the indicator is pointing downwards.
Note:
Once the weather tendency indicator has regi stered a
change in air pressure, it will remain permanently
visualized on the LCD.

distance may be decreased. Please bear this i n mind
when positioning the transmitters. Also the batteries may
be reduced in power for the thermo-hygro transmitter.
CHECKING FOR 868MHz RECEP TION
If the outdoor temperature and humidity data are not being
received within three minutes after setting up (or outdoor
display always show “- -.-” in the outdoor section of the
weather station during normal operation), pl ease check the
following points:
1. The distance of the weather station or transmitters
should be at least 2 meters away from any
interfering sources such as computer monitors or TV
sets.
2. Avoid placing the transmitters onto or in the
immediate proximity of metal window frames.
3. Using other electrical products such as headp hones
or speakers operating on the 868MHz-signal
frequency may prevent correct signal transmission
or reception. Neighbors using electrical devi ces
operating on the 868MHz-signal frequency can also
cause interference.
Note:
When the 868MHz signal is received correctly, do not reopen the battery cover of either the transmi tter or weather
station, as the batteries may spring free from the contacts
and force a false reset. Should this happen accide ntally
then reset all units (see “Setting up” above) otherwise
transmission problems may occur.
The transmission range is around 100 meters from the
thermo-hygro transmitter to the weather station (in open
space). However, this depends on the surroundi ng
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” above).
POSITIONING THE WEATHER STATION
The weather station provides the option of tabl e standing
or wall mounting the unit. Before wall mounting, please
check that the outdoor data can be received from the
desired locations.
33
To wall mount:
1. Fix a screw (not supplied) into the
desired wall, leaving the head
extended out by about 5mm.
2. Place the weather station onto the
screw, using the hanging hole on the
backside. Gently pull the weather
station down to lock the screw into
place.

and humidity readings are receivable. In event that the
signal is not received, relocate the thermo-hygro
transmitter or the weather station slightly as this may help
the signal reception.
Mounting at a sheltered place. Avoid direct
rain and sunshine.
The thermo-hygro transmitter can be placed
