6.2 Inserting the batteries in the outdoor transmitter
• Open the screwed battery compartment of the outdoor transmitter.
• The slide switch for channel selection is at position 1 (default).
• Insert two new batteries 1,5 V AAA, polarity as illustrated.
• Close the battery compartment again.
6.2.1 Reception of the outdoor values
• The outdoor values of the outdoor transmitter will be transmitted to the base station.
The displays of the outdoor values are flashing "--.-".
• On the display of the base station appear the channel number, the outdoor humidity
and the outdoor temperature in °C (default).
• If the reception of the outdoor values fails within three minutes, "- -" appears on the
display. Check the power adapter and the batteries of the transmitter and try it again.
Check if there is any source of interference.
• You can also start the outdoor transmitter search manually later on (for example when
the outdoor transmitter is lost or the batteries are changed).
• Hold the CH button on the base station for three seconds.
• "---" appears on the display.
• Press the TX button in the battery compartment of the outdoor transmitter.
• The device will alert you with a beep and the base station receives the values from the
outdoor transmitter.
• After successful installation close the battery compartment of the outdoor transmitter
carefully.
6.3 Reception of the DCF frequency signal
• After the reception of the outdoor values, the device will now scan the DCF frequency
signal and the DCF symbol will be flashing on the display.
• To avoid interference, the backlight (and the USB output) turns off during the reception
of the radio controlled clock.
• When the time code is received successfully after 2-12 minutes, the radio-controlled
time and the DCF symbol are displayed steadily in the display. The backlight is activat-
ed permanently.
• You can start the initialization manually.
• Press and hold the +/RCC button.
• The DCF symbol will be flashing.
• The continuous backlight will turn off automatically.
• Interrupt the reception by pressing the +/RCC button again for three seconds. The DCF
symbol disappears.
• The DCF reception always takes place hourly between 2:00 and 5:00 o'clock in the
morning. If the reception is not successfully received until 5:00 o'clock, the next
receive operation is again at 2:00 o'clock in the morning.
There are three different reception symbols:
flashing
- reception is active
stays
- reception is very good
no symbol
- no reception / time is manually set

• If the clock cannot detect the DCF-signal (for example due to disturbances, transmit-
ting distance, etc.), the time can be set manually. The DCF symbol disappears and the
clock will then work as a normal quartz clock. (see: Manual settings).
6.3.1 Note for radio-controlled time DCF
The time base for the radio-controlled time is a caesium atomic clock operated by the
Physikalisch Technische 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. Your radio-controlled clock receives this signal and converts it
to show the precise time. 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 with-
in 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 natu-
rally weakened. In extreme cases, please place the unit close to a window to improve
the reception.
• During night-time, the atmospheric interference is usually less severe and reception is
possible in most cases. A single daily reception is adequate to keep the accuracy devi-
ation under 1 second.
6.4 Inserting the batteries in the base station
• The batteries will operate as a backup power source in case of power failure.
• For a permanent backlight use the supplied power adapter.
• Open the battery compartment at the back of the base station.
• Insert two new batteries 1,5 V AAA into the battery compartment. Make sure the polar-
ity is correct.
• Close the battery compartment again.
7. Operation
• During the operation, all successful settings will be confirmed by a brief beep tone.
• The device will automatically quit the setting mode if no button is pressed for a long
period of time.
• Press and hold the +/RCC or -/°C/°F button in the setting mode for fast running.

7.1 Manual settings

• Press and hold the SET button in normal mode for two seconds, to enter the setting
mode.
• The continuous backlight will turn on automatically.
• TIME ZONE and 0 (default) will be flashing on the display.
• Press the +/RCC or -/C/°F button to make the time zone correction.
• Press the SET button again.
• TIME appears on the display.
