Automatic time synchronisation
The transmitter for the DCF radio signal in Germany is near Frankfurt and also reaches other European
countries. Further information on the DCF radio signal is available in Internet.
•
After inserting the battery, the device automatically scans for the DCF radio signal to complete
synchronisation of the time. The radio signal icon flashes, thus indicating that scanning for the signal
has started. When the radio signal icon is displayed continually, the DCF radio signal has been received.
•
To ensure that time deviations are kept as small as possible, a daily time synchronisation occurs at night
at 2:00 a.m. If this synchronisation is unsuccessful (the radio signal icon disappears from the LC
display), 4 further attempts are made at the top of the next hours. A time synchronisation once a day
normally suffices to keep the time accurate to the second.
•
Press the
WAVE
button (14) to start the time synchronisation manually. Press the
WAVE
button again to
interrupt time synchronisation. If no signal is received within 7 minutes, signal scanning stops (the radio
signal icon disappears) and restarts at the top of the next hour.
•
Since there is less atmospheric disturbance at night, signal reception should be possible during the
night.
•
Signal reception is weaker in buildings with cement walls, e.g. office buildings or basements. If no signal
is received in such cases, position the device in the vicinity of a window.
Inserting the battery
Open the battery compartment
(16)
on the rear side of the device and insert a 1.5 V battery, type AAA/LR03
(not supplied with the device). Pay attention to correct polarity (+ / -) as indicated in the battery compartment.
After inserting the battery, an acoustic signal is issued and the radio signal icon appears in the LC display
above the Alarm icon
(10)
at the top right. Close the battery compartment. The device then automatically
attempts to receive the DCF radio signal in order to display the time. If no signal is received, set the time
manually.
