The altitude flashing , please use “+ “, “-“to set the altitude of your position, then press
“HISTORY”, weather symbol flashing, pls use “+ “, “-“ to choose the weather .
The station is now connecting to the outdoor sensor. This process takes about 3 minutes.
Then the display shows the outdoor temperature and humidity, in case of failure of reception ,
pls press“CHANNEL“for more than 3 seconds to receive again.
the automatic receiving of the DCF radio signal begins after 3 minutes of outdoor reception.
This RCC reception process is going on,the flashing symbol “radio tower“ appears in the time
display area at the same time.
Once radio signal receiving is successful, the display shows the symbol “radio tower“
continuously. No flashing.
If, due to bad reception, or no RCC automatic time reception is possible, follow the steps below
manually.
DCF radio signal search starts automatically about 3 minutes after battery exchange. The
“radio tower” signal is flashing.
Press“+“ “-“ for more than 3 seconds to enter or quit the Radio controlled signal reception
The clock synchronizes with the DCF radio signal automatically and daily from AM 1:00 to
3:00 to correct potential time deviations each hour. If the synchronization is unsuccessful
(“radio tower“ symbol disappears), a further synchronization attempt is made From 4:00 and
5:00 until success. This process is repeated up until 5:00 AM. If still not success, daily
reception stop.
Information
Flashing “radio tower” symbol stands for DCF radio signal reception started.
Continuous “radio tower” symbol stands for DCF radio signal reception successful.
Please observe a minimal distance of 2.5m to sources of interference such as televisions or
computer screens.
The radio signal reception is weaker in rooms with concrete walls (e.g. in the basement) and
in office buildings. For extreme cases, please put the clock near a window.
There are less atmospheric disturbances at night. A radio time signal reception is usually
possible at that time. One synchronisation per day is sufficient to keep the time display
accuracy at 1 second.
Tip
You can adjust the time manually in case the clock cannot receive the DCF radio signal (due to
interferences, large distance to the sender, obstructions like mountains, etc.) As soon as the radio
signal can be received, the clock will be adjusted automatically.
Radio signal sender coverage up to 1500km distance to Frankfurt/Main.
Manual time set-up (the most important is to quit the reception of radio
controlled signal by holding together “+ “and“-” for 3 seconds in case of
the “radio tower”symbol flashing before set-up )
Information:
The clock automatically changes from set-up mode to time display mode if no keys are
pressed for 20 seconds.
Explanation for the time zone display:
You can manually adjust the clock to the time zone of a country (up to 1500km distance to
Frankfurt/Main) where the clock receives the DCF signal but where the actual time differs
from the time received.
If, e.g. the time in a given country is 1 hour ahead of the German time, set the time zone
display to 01. The clock is now DCF controlled but the time is one hour ahead.
