4. Getting started
• Place the base station and the outdoor transmitter on a desk with a distance of approxi-
mately 1.5 meter. Avoid getting close to possible interference sources (Electronic devices
and radio installations).
• Open the battery compartment of the outdoor transmitter.
• Insert two new batteries 1,5 V AAA into the battery compartment of the outdoor transmit-
ter. Make sure the polarities are correct.
• Remove the protecting foil from the display of the base station.
• Connect the base station to the attached power adapter. Insert the adapter into the jack at the
base station and connect the power adapter to a wall socket. Important! Make sure that your
household voltage is not higher than 240V! Otherwise your device may be damaged.

SUN - Wireless weather station
• The device will alert you with a beep and all LCD segments will be displayed for a short
moment.
• The backlight is activated permanently.
• The indoor temperature will be displayed on the base station and the base station will scan
the outdoor temperature and the reception symbol will be flashing.
• If the reception of the outdoor temperature fails, "- -" appears on the display. Check if
there is any source of interference. After the reception of the radio-controlled time you can
start the initialization for the outdoor transmitter manually. Press and hold ▼ button for
3 seconds. The base station will scan the outdoor temperature.
4.1. 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 3-7 minutes, the radio-controlled time
and the DCF symbol are displayed steadily in the display.
• Caution: During the DCF time reception period, backlight turns off and no outdoor tem-
perature will be transmitted.
• If there is no reception possible, manual initialization can be helpful.
• Press the WAVE button.
• The DCF symbol will be flashing.
• Interrupt the reception by pressing the WAVE button again. The DCF symbol disappears.
• The DCF reception always take place at 1:00 o'clock in the morning until 5.00 o'clock. If
the reception is not successfully received at 5:00 o'clock, further attempts will be made
again at 1:00 clock in the morning.
• 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 normal quartz clock. (see: Manual setting of the clock and calendar).
4.1.1 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.
