6. Getting started
6.1 Insert batteries
• Open the battery compartment of the display unit and the
transmitter (screwed) and place both instruments on a desk
with a distance of approximately 1.5 meter. Check that no other
electronic devices are close.
• Insert the batteries 2 x 1,5 V AAA into the battery compartment
of the transmitter and immediately afterwards 2 x 1,5 V AA in
the display unit, observing the correct polarity.
6.2 Reception of outdoor temperature
• The display unit automatically starts scanning the 433 MHz signal
to register the transmitter unit after batteries are inserted.
flashes on the LCD of the display unit.
• Note: DO NOT PRESS ANY KEY during the learning period.
After outdoor temperature is displayed you can place your
transmitter outdoors at the final destination. If the outdoor
temperature is not displayed or if any key is pressed before the
outdoor temperature signal is received and when changing
batteries you will need to follow the battery installation pro-
cedure again. Please wait 10 seconds before inserting the
batteries again.
6.3 Radio-controlled time reception
• The clock will scan the DCF frequency signal (max. 10 min.) and
the DCF symbol flashes on the LCD.
• When the signal is received successfully, the radio-controlled
time and the DCF symbol appear permanently.

• If the reception fails, scanning stops and will be repeated every
hour.
• The time base for the radio-controlled time is a Caesium Atom-
ic Clock operated by the Physikalisch Technische Bundesanstalt
Braunschweig which has a time deviation of less than one sec-
ond 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 in summer or wintertime.
The quality of the reception depends greatly on the geographic
location. In normal cases, there should be no reception prob-
lems within a 1,500 km radius around Frankfurt.
Please take note of the following:
• The recommended distance from any interfering sources like
computer monitors or TV sets is a minimum of 1.5 - 2 metres.
• Within ferro-concrete rooms (basements, superstructures), the
received signal is naturally weakened. In extreme cases, please
place the unit close to a window and/or point its front or back
towards the Frankfurt transmitter.
• During night-time, the atmospheric disturbances are usually
less severe and reception is possible in most cases. A single daily
reception is adequate to keep the accuracy deviation under
1 second.
• In case the clock cannot detect the DCF-signal (for example due
to disturbances, transmitting distance, etc.), the time can be set
manually. The clock will then work as a normal quartz clock.
6.4. Manual setting
• Hold "SET" button for 3 seconds. The "00" digit is flashing and
you can adjust the time zone (+12/-12) with the "+" button.
The time zone is used for the countries where the DCF signal
can be received but the time zone is different from the German
time (e.g. 1=one hour later).
• Press "SET" button again. The 24 H digit is flashing. Press "+"
button to choose 12 H (PM appears after 12 o'clock) or 24 H
system. Confirm with "SET" button.
