Getting started
Insert the batteries
y Remove the protective film from the display.
y Place the base station and the transmitter on a table at a distance of about
1.5 meters from each other. Avoid being close to possible sources of interfer-
ence such as electronic devices and radio equipment.
y Open the battery compartment of the transmitter and insert two new AA 1.5 V
batteries, polarity as illustrated.
y All LCD segments will be displayed for a short moment.
y The transmitter's display shows the current temperature and humidity. The
switch is set to channel 1.
y Close the battery compartment.
y Insert three new batteries 1,5 V AA into the battery compartment of the base
station. Make sure the polarities are correct.
y All LCD segments will be displayed for a short moment.
y The indoor temperature and humidity appear on the display.
Outdoor values reception
y After the batteries are inserted, the outdoor values will be transmitted to the
base station. The reception symbol for the transmitter flashes.
y If the reception of the outdoor values fails, "- -" will be shown steadily on the
base station display. Check the batteries and try it again. Check if there is any
source of interference.
y You can also start the transmitter search manually later (e.g. if the transmitter
signal is lost or if the batteries are changed). Press and hold the CHANNEL
button for three seconds. The last registered transmitter (channel) will be
cancelled.
y Press the TX button in the transmitter's battery compartment.
y The reception symbol of the transmitter flashes and the base station will scan
the outdoor values.
Reception of the DCF frequency signal
y After the reception of the outdoor values, the clock will now scan the DCF
frequency signal and the DCF symbol flashes on the display.
y When the time code is successfully received after 3-10 minutes, the radio-con-
trolled time and the DCF symbol will be shown steadily on the display.
y The DCF reception always takes place at 1:00, 2:00 and 3:00 o'clock in the
morning. If the signal is not successfully received, further attempts will be taken
at 4:00 and 5:00 o'clock.
y You can also activate the DCF reception manually. Press the -/MIN button for 3
seconds. The DCF reception symbol will be flashing.
y Press and hold the -/MIN button again for 3 seconds to stop the reception
process. The DCF reception symbol disappears.

y There are 3 different reception symbols:
y
flashing symbol - reception is active
solid - reception is successful
y
no symbol - no DCF reception
y
y If the clock cannot detect the DCF-signal (e.g. due to interference, transmitting
distance, etc.), the time can be set manually.
y The clock will then work as a normal quartz clock (see: "Manual settings").
Note on radio-controlled time
y The time is transmitted from an atomic clock near Frankfurt am Main by a
DCF-77 (77.5 kHz) frequency signal with a range of about 1,500 km. Your ra-
dio-controlled clock receives the signal, converts it and always shows the exact
time. The adjustment of Daylight Saving Time and Standard Time
is also automatic.
y Avoid being close to possible sources of interference that may affect radio
reception (see "Location and mounting").
y During night-time, the atmospheric interference is usually less severe. A single
daily reception is adequate to keep the accuracy deviation under 1 second.
Operation
y The device will automatically quit the setting mode if no button is pressed for
20 seconds.
y Press and hold the MAX/+ or -/MIN button in setting mode for fast mode.
Manual settings
y Press and hold the SET button for three seconds to enter the setting mode.
y The first adjustable value flashes on the display.
y Use the MAX/+ or -/MIN button to make the desired setting, while the value
flashes.
y Confirm with the SET button and go to the next setting.
y The sequence is shown as follows:
y
DCF reception ON/OFF (default: DCF ON)
Time zone -12/+12 (default: ZONE 00)
y
Hours, minutes
y
Auto-reset AUTO MIN MAX ON/OFF (default OFF)
y
DCF reception
y By default, the DCF reception is activated (DCF ON) and after successful recep-
tion of the DCF signal no manual time setting is necessary.
y In the setting mode, you can deactivate (DCF OFF) or activate again the DCF
reception using the MAX/+ or -/MIN button.
y Once the DCF time reception is deactivated the clock must be manually set.
No time zone will appear.
y If the DCF reception is activated, the manually set time will be overwritten by
the DCF time when the signal is received successfully.
