6. Getting started
•
Place the radio-controlled clock and the transmitter on a desk with a distance of approximately 1.5
meter. Avoid getting close to possible interference sources (Electronic devices and radio installations).
•
Open the battery compartment of the radio-controlled clock and remove the battery insulation strip.
All LCD segments will be displayed briefly. Close the battery compartment again.
•
Open the battery compartment of the outdoor transmitter by extending the stand and pull the lid
down. Remove the battery insulation strip. All LCD segments will be displayed briefly. The signal lamp
will be lighting briefly. The outdoor temperature will be displayed. Press the
°C/°F
button inside the
battery compartment of the transmitter to change between °C (Celsius) or °F (Fahrenheit) as tempera-
ture unit. Close the battery compartment again.
•
The indoor temperature will be displayed on the radio-controlled clock and the radio-controlled clock
will scan the outdoor temperature and the reception symbol will be flashing.
•
If the outdoor temperature will not be displayed on the radio-controlled clock, “- -” appears on the
display. Check the batteries and try it again. Check if there is any source of interference.
•
You can start the initialization manually. Press and hold the
SEARCH
button on the radio-controlled
clock for three seconds. The radio-controlled clock will scan again the outdoor temperature. Press and
hold
RESET
button in the battery compartment of the outdoor transmitter for three seconds.
7. Radio-controlled time reception
•
The clock will now scan the DCF frequency signal and the DCF symbol will be flashing. When the
time code is received successfully after 5 minutes, the radio-controlled time, the date and the DCF
symbol are displayed steadily in the display.
•
If there is no reception possible, manual initialization can be helpful.
•
Press and hold
– / °C/°F
button for three seconds.
•
The DCF symbol will be flashing .
•
Interrupt the reception by pressing the
– / °C/°F
button again for three seconds. The DCF symbol dis-
appears.
•
The DCF reception always take place at 3:00 o'clock in the morning. If the reception is not successfully
received at 3:00 o'clock, it shall be held further attempts at 6:00 o'clock.
•
There are three different reception symbols:
flashing - reception is active
stays - reception is successful
No symbol - no reception / time is manually set
•
If the clock cannot detect the DCF-signal (for example due to disturbances, transmitting distance,
etc.), the time can be set manually. The DCF symbol disappears and the clock will then work as a nor-
mal quartz clock. (see: Manual setting of the clock and calendar).
7.1 Note for radio-controlled time DCF:
The time base for the radio-controlled time is a caesium atomic clock operated by the Physikalisch Tech-
nische Bundesanstalt Braunschweig. It has a time deviation of less than one second in 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. Changeover from summer time or winter
time is automatic. In Daylight Saving Time DST is shown on the LCD. The quality of the reception
depends mainly on the geographic location. Normally there should be no reception problems within a
1,500 km radius around Frankfurt.
Please take note of the following:
•
The recommended distance to any interfering sources like computer monitors or TV sets is at least 1.5-
2 meters.
•
Inside ferro-concrete rooms (basements, superstructures), the received signal is naturally weakened.
In extreme cases, please place the unit close to a window to improve the reception.
•
During nighttime, the atmospheric interference is usually less severe and reception is possible in most
cases. A single daily reception is adequate to keep the accuracy deviation under 1 second.
8. Operation
•
During the reception of the outdoor temperature and the time is a button operation not possible.
•
Press and hold
+ / 12/24
or
– / °C/°F
button in the setting mode for fast running.
•
The instrument will automatically quit the setting mode if no button is pressed within 15 seconds.
8.1 Manual setting of the clock and calendar
•
Press and hold
MODE
button for three seconds.
•
The hour digit will be flashing .
•
Press the
+ / 12/24
or
– / °C/°F
button to adjust hours.
•
Press the
MODE
button again and the setting sequence is shown as follows: Minutes, seconds, year,
date, month/day sequence (American version) or day/month (European version), month, day, the lan-
guage of the day-of-the-week (default: GER) and time zone (default: 0) and adjust the settings with
the
°C/°F
button or
+ / 12/24
button.
•
Confirm the setting with the
MODE
button.
•
Press the
+ / 12/24
button in normal mode to choose between 24- and 12 HR system (AM or PM
appears on the display).
•
The manually set time will be overwritten by the DCF time when the signal is received successfully.
