batteries. To install and replace the batteries, please
follow the steps below:
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 inside battery compartment).
3. Replace compartment cover.
DO NOT SET THE CLOCK.

TO INSTALL AND REPLACE BATTERIES IN THE TEMPERATURE
TRANSMITTER
The transmitter uses 2 x AA, IEC LR6, 1.5V batteries. To install and
replace the batteries, please follow the steps below:
1. Remove the cover.
2. Insert the batteries, observing the correct polarity (see marking
inside battery compartment).
3. Replace the batterycover on the unit.
Alkaline batteries are recommended for use in both units. Avoid
using rechargable batteries.
SETTING UP:
1. Insert the 2 x AA, IEC LR6, 1.5V batteries into the transmitter (See “To install and
replace batteries in the Temperature Transmitter” above).
2. Within 3 minutes, insert 2 x AA, IEC LR6, 1.5V batteries into the Weather wall clock as
indicated above (see "To install and replace batteries in the Weather wall clock“
above).
3. Once the batteries are in place, all segments of the LCD will light up briefly and a brief
beep sound will be hear. Then the indoor temperature “OF” and outdoor temperature - - -,
the time as 0:00, the date as 1/1, and weekday will be displayed.
4. Do not press any buttons for 10 minutes
5. The Weather wall clock will start receiving data from the transmitter. The remote
temperature will then be displayed on the Weather wall clock. If the outdoor temperature
is not displayed 90 seconds after inserting the batteries into the receiver, all batteries are
needed to be removed and wait for at least 1 minute for reset from step 1.
6. The DCF time code reception will automatically start. This takes typicallybetween 3 - 5
minutes in good conditions. This time period is an excellent opportunity to locate the
transmitter in suitable location outdoors. In order to ensure sufficient 868MHz
transmission however, this should under good conditions be no more than 100 meters
from where the Weather wall clock will be finally positioned (see notes on “Positioning”
and “868MHz Reception”).
7. If after 10 minutes the DCF time has not been received, use the SET key to enter into the
set mode and change either the time or date in order to activate the DCF reception. The
clock will then automatically attempt to receive the DCF time. When this is successful,

22
the received time will override the manually set time. The date is also updated with the
received time (Please refers to notes on “DCF Radio controlled time” and “Manual time
setting”).
Note:
In the event of changing batteries of the unit ensure that 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.
RADIO CONTROLLED TIME:
The time base for the radio controlled time is a Cesium Weather wall 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 frequencysignal DCF-77 (77.5 kHz) and has a transmitting range of
approximately1,500 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.
Once the outdoor temperature is displayed on the Weather station, 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 it. When the time code is
received, the DCF tower becomes permanently lit and the time will be displayed.
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 trytakes place at 02:00 next day.
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 metres.
• 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.

MANUAL SETTINGS
Note:
If the weather wall clock has already successfully received the DCF time signal and
displays the correct time and date, then the Manual settings can be skipped.
After completion of the above described procedures in “Setting up”, the manual setting modes
can be entered bypressing the SET key. The following settings can now be programmed:
• Time zone setting
• Language display setting
• Manual time setting

THE WEATHER FORECASTING ICONS:
There are 3 weather icons on the middle section of LCD 2, which 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, 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 icons 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 displayed forecasts the weather 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 rain.
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 first floor of a house), remove the
batteries and re-insert them after about 30 seconds. By doing this, the Weather Station will not
