OPERATION
•
Remove the battery compartment cover (C
1
) on the backside of
the device. Insert
2
new batteries (type:
1.5
V, AA) observing the
correct polarity.
•
Replace the batteries when the display quality weakens.
Once the batteries have been inserted, the clock starts searching for
the radio clock signal of the atomic watch in Frankfurt/Mainflingen.
This will take approx.
3
to
10
minutes, provided there is no interference
with the radio communication.
*
When receiving the radio signal, the device will automatically
set the date and time (DCF77), with the radio signal icon being
displayed at the same time.
If the clock cannot receive the time signal, the radio signal icon (
A4
)
does not light up. In such a case you may adjust the time manually.
If you do not want to use any other functions of the clock, the
installation process is thereby completed. Refer to the instructions
below for further functions and features regarding the operation of
this device.
Information on synchronizing the radio clock signal
Time and date are radio-controlled. The current time
is synchronized to the radio signal from Frankfurt,
Germany (DCF77). DCF77 is a time signal broadcast as
encoded time information on a normal frequency of
77.5 kHz. The transmitting power is approx. 50 kW with
a broadcasted power of approx. 30 kW and coverage
of approx. 1500 km in the vicinity of Frankfurt/Main
(Mainflingen).
Radio signal
icon (
A4
)
When you first start the clock, it will automatically search for the radio
signal and the radio signal starts flashing. If the radio receives the
time signal, the symbol will remains lit on the display. A flashing symbol
means the signal is being received.
Daylight saving time (DST)
In summer the clock automatically switches to daylight saving time
and in winter returns to standard time.
