The automatic receiving of the DCF77 radio signal begins after 3 minutes of outdoor RF
reception.
This RCC reception process is going on,t
he 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
Reception of radio controlled signal
DCF77 radio signal search starts automatically about 3 minutes after battery exchange.
The “radio tower”
signal is flashing.
Press
“IN”
for more than 3 seconds to enter or quit the Radio controlled signal reception
Flashing “radio tower”
symbol stands for DCF77 radio signal reception started.
Continuous “radio tower”
symbol stands for DCF77 radio signal reception
successful.
If the synchronization is unsuccessful, the
“radio tower“
symbol disappears.
The clock synchronizes with the DCF77 radio signal automatically and daily from 1:00AM
to 3:00AM to correct potential time deviations each hour. If the reception is unsuccessful,
a further synchronization attempt is made at 4:00AM and 5:00AM until success. If it is still
not success at 5:00AM, the daily reception will stop.
Information
Please observe a minimal distance of 2.5m to sources of interference such as televisions
or computer screens.
The radio signal is weaker in rooms with concrete walls (e.g. in the basement) and in
office buildings. For extreme cases, please put the main unit near a window.
There are less atmospheric disturbances at night. A radio time signal reception is usually
possible at that time. One synchronization per day is sufficient to keep the time display
accuracy at 1 second.
Hint
You can adjust the time manually in case the clock cannot receive the DCF radio signal (due to
interference, large distance to the sender, obstructions like mountains, etc.) As soon as the
radio signal can be received, the clock will be adjusted automatically.
