SETTING UP:
Note: This weather station receives only one outdoor tra nsmitter.
1. First, insert the batteries into the Temperature transmitter. (see “Install
and replace batteries in the temperature transmitter“).
2. Immediately after and 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. Following 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 stati on will start receiving data
from the transmitter. The outdoor temperature and the signal reception
icon should then be displayed on the Weather stati on. 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 however, this should
under good conditions be a distance no more t han 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 recei ved 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.
DCF RADIO CONTROLLED TIME
The time base for the radio controlled time i s a Cesium Atomic Clock operated
by the Physikalisch Technische Bundesanstal t Braunschweig which has a time
deviation of less than one second in one milli on 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.
23
Page 6
The quality of the reception depends greatly on the geographic location. In
MIN/MAX
normal cases, there should 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 on until 06:00am, or until the recepti on 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 foll owing:
•
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 si ngle 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 secti on of LCD which can be
displayed in any of the following combinations :
Sunny
For every sudden or significant change in the air pressure, the weather icons
will update accordingly to represent the change i n 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.
sunny intervals
Rainy
28
Page 11
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 a nd 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 that the ai r-pressure is increasing and the
weather is expected to improve, but when i ndicator 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 i ndicator is pointing downwards
29
Page 12
together with cloud and sun icons, then the l ast noticeable change in the
icon

Outdoor
MAX record
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 regi stered a change in the air
pressure, it will remain permanently visualized on the LCD.
INDOOR TEMPERATURE AND MIN/MAX RECORDS
The indoor temperature and indoor MIN/MAX records are displayed on the last
section of the LCD.

RESETTING THE INDOOR AND OUTDDOR MIN/MAX RECORDS
Note: All the MIN/MAX records will be reset at the same time.
1. In normal display mode, press and hold the MIN/MAX RESET key for 3
seconds. This will reset the indoor and outdoor MIN/MAX temperatures.
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 displ ay 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 i n the immediate proximity
of metal window frames.
3. Using other electrical products such as headphones or speakers
operating on the same signal frequency (868MH z) may prevent correct
signal transmission and reception.
4. Neighbours using electrical devices operati ng 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
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 uni ts have to be reset (see Setting
up).
POSITIONING THE WEATHER STATION:
The weather Station may be hung onto wall easily or free standing.
Choose a sheltered place. Avoid direct rain and sunshine.
31
Page 14
