SETTING UP
Note: This weather station re ceives only one outdoor tran smitter.
1. First, insert the batteri es in the transmitter (see “How to install and repla ce batteries
in the thermo-hygro trans mitter” above).
2. Within 30 seconds of poweri ng up the transmi tter, insert batteries i n the weather station
(see “How to install and repla ce batteries in the w eather station ” above). O nce the
batteries are in pl ace, all segments of the LCD wi ll light up briefl y and a short signal
tone will soun d. T hen the indoor temperat ure, humidity and t he time as 0:00 will be
displayed. If these informati on are not displ ayed on the LCD after 60 seconds, re move
the batteries and wait for at least 60 seconds before rei nserting them. O nce the indoor
data is displayed user may proceed to the next step.
3. After the batteries are i nserted, the weat her station will start recei ving data signal from
the transmitter. The o utdoor temperature and humi dity data should then be di splayed
on the weather station. If t his does not happen after 2 mi nutes, the batteri es will need
to be removed from bot h units and reset from step 1.
4. In order to ensure s uccessful 868 MHz transmissi on, the distance betwee n the weather
station and the transmitte r should be within 100 meters (se e notes on “Positioning ”
and “868 MHz Reception ”).
5. Once the outdoor data rec eption test period i s completed, the DCF tower i con in the
clock displ ay will start flashing in the upper l eft corner. This indicates that t he clock has
detected that there is a r adio signal present and i s trying to receive i t. When the time
code is received, the DCF to wer becomes perma nently lit and the time wi ll be
displayed.

DCF RADIO CO NTROLLED TIM E
The time base for the radi o controlled time i s a Cesium Atomic Cl ock operated by the
Physikalisch Tec hnische Bundesanstalt Braunsc hweig which has a time deviati on of less than
one second in one milli on years. The time i s coded and transmitted from Mai nflingen near
Frankfurt via frequency sig nal DCF-77 (77.5 kH z) and has a transmitti ng range of
approximately 1,500 km. Your radio-controll ed weather station receives t his signal and
converts it to show t he precise time in summer or wintertime.
The quality of the reception depends greatl y on the geographic l ocation. In normal cases,
there should be no reception problems within a 1,500 km r adius of Frankf urt.
DCF reception is do ne twice daily at 02:00 and 03:00 am. I f the recepti on is not successful at
03:00 am, then the next reception takes place t he next hour and so on until 06:00am, or until
the reception is s uccessful. If the reception is not s uccessful at 06:00 am, t hen the next
attempt will take place the next day at 02:00 am.
If the tower icon flas hes, but does not set t he time or the DCF tower does not appear at all ,
then please take note of the following:
Recommended distance to a ny interfering sources l ike computer monitors or TV set s is
a minimum of 1.5 - 2 meters.
Within ferro-concrete rooms ( basements, superstructures), t he received signal i s
naturall y weakened. In extreme cases, please pl ace the unit close to a wi ndow and/ or
point its front or back toward s the Frankfurt tr ansmitter.
During nighttime, t he atmospheric disturbances are usually less severe and reception is
possible in most cases. A singl e daily recepti on is adequate to keep the acc uracy
deviation below 1 second.

WEATHER FORECASTING IC ONS:
The weather ico ns in the second section of LCD ca n be displayed in any of t he following
combinations:
For every sudden or signifi cant change in the air press ure, the weather i cons will update
accordingly to represent t he change in weather. If t he icons do not change, t hen it means
either the air pressure has not changed or the cha nge has been too sl ow for the weather
station to register. However, i f the icon displ ayed is a sun or raining clo ud, there will be no
change of icon if t he weather gets any better (wi th sunny icon) or worse (wi th rainy icon) since
the icons are already at t heir extremes.
The icons displ ayed forecasts the weather i n terms of getting better or worse a nd not
necessaril y sunny or rainy as each icon indi cates. For example, if the c urrent weather is
cloudy and the rainy icon i s displayed, i t does not mean that the product is faulty because it i s
not raining. It simpl y means that the air pressure has dropped and the weat her is expected to
get worse but not necessarily rainy.
Note:
After setting up, readi ngs for weather forecasts s hould be disregarded for t he next 12-24
hours. This will allow sufficient time for the w eather station to coll ect air pressure data at a
constant altitude and t herefore result in a more acc urate forecast.
Common to weather forecasti ng, absolute accuracy ca nnot be guaranteed. The weather
forecasting feature is est imated to have an accuracy l evel of about 75% d ue to the varying
areas the weather station has been designed for use. In areas that experi ence sudden
changes in weather (for e xample from sunny to rai n), the weather statio n will be more
accurate compared to use in areas where the weat her is stagnant most of t he time (for
example mostly sunny).
If the weather stati on is moved to another locati on significantly higher or l ower than its initial
standing point (for example from the ground fl oor to the upper floors of a house), discard t he
weather forecast for the next 12-24 hours. By doi ng this, the weather stati on will not mistake
the new location as being a possible change i n air-pressure when really i t is due to the slight
change of alti tude.
WEATHER TENDENCY INDIC ATOR
The weather tende ncy indicators (located on the l eft side of the weather i cons) are working
together with the weat her icons. When the i ndicator points upwards, it mea ns that the air -
pressure is i ncreasing and the weather is expected to i mprove, but whe n indicator points
downwards, the air-pre ssure is dropping and the weat her is expected to become worse.
Taking this i nto account, one can see how the weat her has changed and is exp ected to
change. For exampl e, if the indicator is pointing dow nwards together wit h cloud and sun
icons, then the last noticeable change in the weat her was when it was s unny (the sun icon
only). Therefore, the next change in the weather wi ll be cloud with rain i cons since the
indicator is pointi ng downwards.
Note:
Once the weather te ndency indicator has regi stered a change in air pressure, it w ill remain
permanently visuali zed on the LCD.
