SETTING UP: 
1.  Firstly, slide open the battery cover at the back of the alarm 
clock as indicated above. 
2.  Checking the correct polarization, insert 1 x AA, IEC LR6, 1.5V 
battery into the battery compartment and replace the cover. 
3.  Once the battery is in place, all segments of the LCD will light up 
briefly and a short signal tone will sound. Then the time as “0:00” 
and the indoor temperature will be displayed. If the indoor 
temperature is not displayed after a few seconds, remove the 
battery and wait for at least 10 seconds before reinserting it. 
4.  If after 10 minutes the DCF time has not been received, reset the 
alarm clock and manually enter the time. The clock will 
automatically attempt each hour to receive the DCF time. When 
this is successful, the received time will override the manually 
set time. The date is also updated with the received time (Please 
refer also to notes on “Radio controlled time” and “Manual 
time setting”).

RADIO CONTROLLED TIME: 
The time base for the radio-controlled time is a Cesium Atomic 
Clock operated by the Physikalisch Technische Bundesanstalt 
Braunschweig which has a time deviation of less than one second in 
every 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. The alarm clock receives this 
signal and converts it to show the precise time and so when within 
this range the received time is completely accurate. 
 
CHECKING FOR DCF-77 RECEPTION: 
The alarm clock will automatically start scanning for the DCF-77 
frequency signal after the battery is inserted. In normal surroundings 
(for example away from interfering sources such as TV sets), it 
takes between 3-5 minutes to receive the signal. If after 10 minutes 
of inserting the battery into the alarm clock and the DCF-77 signal is 
not received, then check the following list before manually setting 
the time (see Manual time setting below): 
1.  The distance of the alarm clock should be at least 1.5-2.0 meters 
away from interfering sources such as computer monitors or TV 
sets. 
2.  Avoid placing the alarm clock onto or in the immediate proximity 
of metal doors, window frames or structures. 
3.  Within thick concrete rooms such as basements and tower 
blocks, the DCF-77 signal is naturally weaker. In extreme cases, 
place the alarm clock closer to a window and/or point its front or 
rear towards the general direction of the Frankfurt transmitter 
(avoid placing near metal frames and structures).  
 
Note:  
Users may be located in areas where atmospheric disturbances are 
the direct cause for not receiving the DCF-77 frequency signal. 
During nighttime, atmospheric disturbances are usually less severe 
and reception is possible in most cases. With a single daily 
reception, it is adequate for the alarm clock to keep time deviation to 
below 0.5 seconds in a period of 24 hours. 
 
When reception is successful, the DCF-77 tower icon will start 
flashing on the LCD as a sign that the signal has been found and 
reception is being attempted. Once the signal is “locked”, the DCF-
77 tower icon will stay fixed on the LCD and the received time will 
automatically correct the manually set time. As well as the time, the 
date will also be received by the alarm clock which is displayed 
accordingly in the calendar section of the LCD.  
 
LCD 1- MANUAL TIME SETTING MODE: 
In some cases after inserting the battery, the alarm clock may not 
be able to receive the DCF-77 signal. In this situation, the time 
should be manually set (before manual setting see Checking DCF-
77 Reception above). 
1.  Press and hold the MODE/MIN key for 2 seconds, (the time zone 
and snooze time will be displayed), then press the MEMO key. 
2.  Set the time by pressing the AL/HR key to change the hour and 
the MODE/MIN key to enter the minutes (each press or holding 
the keys down will increase the digits by one) 
3.  Once the time is set, either press the MEMO key to change the 
Calendar setting or press the SNOOZE key to exit or wait for 
automatic timeout to exit the Manual time setting mode. 
 
Note: 
The alarm clock will still try to receive the signal every hour despite 
it being manually set. When it does receive the signal, it will change 
the manually set time into the received time. During reception 
attempts the DCF tower icon will flash. If reception has been 
unsuccessful, then the DCF tower icon will not appear but reception 
will still be attempted the following hour. 
 
LCD 2 – WEATHER FORECAST AND WEATHER 
TENDANCY INDICATORS 
 
THE WEATHER FORECASTING ICONS: 
There are 3 weather icons on the second section of the LCD 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 alarm clock 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 alarm 
clock has been designed for use in. In areas that experience sudden 
changes in weather (for example from sunny to rain), the alarm 
clock will be more accurate compared to use in areas where the 
weather is stagnant most of the time (for example mostly sunny). 
 
If the alarm clock 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 alarm clock 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 air-
pressure is increasing and the weather is expected to improve, but 
when indicator points 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 indicator is pointing 
downwards together with cloud and 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 
with rain 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.
