the clock is activated. This takes typically between 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 433 MHz transmission
however, this should under good conditions be no more than
25 meters from where the Weather station will be finally
positioned (see notes on “POSITIONING THE OUTDOOR

CF-77 RADIO CONTROLLED TIME
he time base for th
T
operated by the Physikalisch Te
Braunschweig which has a time deviation of less than one sec ond 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 should be no reception pr oblems
within a 1500km radius of Frankfurt.
Once the outdoor reception test period is completed, the D CF tower

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:
• Recommended distance to any interfering sources like
computer monitors or TV sets is a minimum of 1.5 - 2 metres.
• W ithin ferro-concrete rooms (base ments, superstructures ), the
received signal is naturally weakened. In extreme cases,
please place the unit close to a window and/or point its front o r

WEATHER FORECAST AND TENDENCY:
The weather forecast icons (Weather man):
One of the 15 different weather icons (featured by Weather man with
different clothing) is displayed in the centre of LCD, which i ndicates
the different forecast weather condition due to air pressure level
(Sunny, Sunny + Cloudy or Rainy) and the current outdoor
temperature:

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 slo w 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 displayed forecasts the weather in terms of getting better
or worse and not necessarily sunny or rainy as each ico n indicates.
For example, if the current weather is cloudy and the rain y 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).
56
If the Weather station is moved to another location significantly
higher or lower than its initial standing point (for e xample 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 p ossibl e
change in air-pressure when really it is due to the slight c hange 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 ten dency
indicators (the upward and downward arrow located near the
Weather man). When the indicator points upwards, it means that the
air-pressure is increasing and the weather is expected to impro ve,
but when indicator points downwards, the air-pressure is dropping
and the weather is expected to become worse.
Therefore, user may see how the weather has changed and is
expected to change. For example, if the indicator is pointing
downwards together with cloudy icons, it means that the last
noticeable change in the weather was when it was sunny (the sunny
icon only). Therefore, the next change in the weather will be the
cloudy icons since the indicator is pointing downwards.
Note:
Once the weather tendency indicator has registered a change in air
pressure, it will remain permanently visualized on the LCD.
57
TOGGLE BETWEEN THE DISPLAY OF INDOOR TEMPERATURE/
HUMIDITY, PRESET ALARM TI ME AND CALENDAR
By pressing shortly the MODE/MIN key, you will toggle between the
following displays:
1. Indoor temperature and humidity;
2. Preset alarm time;
3. Month and day
3. Day and weekday;
COLOUR-CHANGING BACKLIGHT
1. The Weather station has a colour-changing EL backlight
designed for night-viewing. This will light up for about 10
seconds when any button is pressed. The case of the weather
station will also be illuminated when the backlight is ON.
58
2. When the backlight key is s witch "ON ", t h e EL bac klight will be
turned on permanently.
Note: If batteries are used, the permanent switching on the backlight
may drain off the batteries faster.
3. The EL backlight will be turned on when the alarm time is
reached.
433MHz RECEPTION
If the outdoor temperature data are not being received within three
minutes after setting up (or “- -. -” is shown in the outdoor
temperature section of the Weather station after 3 failed atte mpts
during normal operation), please check the following points:
1. The distance of the Weather station or t ransmitter should be
at least 2 metres away from any interfering sources such as
computer monitors or TV sets.
2. Avoid placing the transmitter onto or in the immediate
proximity of metal window frames.
3. Using other electrical products such as headphones or
speakers operating on the 433MHz-signal frequency may
prevent correct signal transmission or reception. Neighbours
using electrical devices operating on the 433MHz-signal
frequency can also cause interferences.
Note:
59
When the 433MHz 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 around 25 metres from the Temp erature
transmitter to the Weather station in open space). However, this
depends on the surrounding environment and interferenc e levels. If
no reception is possible despite the observation of these factors, all
system units have to be reset (see “Setting up” above).

CARE AND MAINTENANCE:
• Extreme temperat ures, vibration and shock should be avoide d
as these may cause damage to the units and gi ve inaccurate
forecasts and readings.
• W hen cleaning the d isplay and casings, use a soft da mp cloth
only. Do not use solvents or scouring agents as they may
mark the LCD and casings.
• Do not submerge the units in water.
• Immediately remove all low powered batteries to avoid
leakage and damage. Replace only with new batteries of the
recommended type.
• Do not make any repair attempts to the units. Retur n it to their
original point of purchase for repair by a qualified engineer.
Opening and tampering with the units may invalidate their
guarantee.
• Do not expose the units to extreme and sudden temperature
changes, this may lead to rapid changes in forecasts and
readings and thereby reduce their accuracy.
