MARBELLA – Wireless pool thermometer
• On the upper display of the base station appear 0:00 and the indoor
temperature and humidity.
• "- -,-°C" flashes on the lower display.
• The base station will scan for 3 minutes the outdoor values. You can
install the pool sensor during this time.
• Close the battery compartment again.
6.3 Installation of the pool sensor
• Turn the screw cover counterclockwise.
• Carefully pull the battery container out of the body and insert 2 x AA
1.5 V batteries with the correct polarity.
• All segments will be displayed briefly.
• On the display of the pool sensor appears the temperature in °C.
• Push the battery container back into the housing.
• Close the cover carefully.
• Pay attention to the sealing ring.
6.4 Outdoor values reception
• After the batteries are inserted, the measuring values of the pool
sensor will be transmitted to the base station.
• If the reception is successfully on the lower display of the base sta-
tion appear the water temperature with the maximum and minimum
values.
• If the reception of the outdoor values fails, "- -,-°C" remains on the
base station display. Check the batteries and try it again. Check if
there is any source of interference.
• As soon as the base station receives the radio-controlled time, you
can start the manual initialisation of the transmitter. Press and hold
the CHANNEL/SEARCH button for three seconds while the indoor val-
ues "in" are shown on the upper display. "- -, -°C" flashes on the
lower display. The base station will scan the outdoor values.
6.5 Radio-controlled time reception
• After the reception of the outdoor values, the clock will now scan the
DCF frequency signal and the DCF symbol flashes on the display.
When the time code is successfully received after 2-10 minutes, the
radio-controlled time and the DCF symbol will be shown steadily on
the display.

• The DCF reception always takes place at 1:00 and 2:00 o'clock in the
morning. If the reception is not successfully received at 3:00 o'clock,
further attempts will be taken at 4:00 and 5:00 o'clock.
• You can also activate the DCF reception manually.
• Press the SET/RCC button. The DCF reception symbol flashes.
• Interrupt the reception by pressing the SET/RCC button again. The
DCF reception symbol disappears.
• There are three different reception states:
flashing – reception is active
solid – reception is very good
No symbol – no reception/time was set manually
• If the clock cannot detect the DCF-signal (e.g. due to interference,
transmitting distance, etc.), the time can be set manually. The DCF
reception symbol disappears and the clock will then work as a nor-
mal quartz clock (see: Manual settings).
6.6 Note on radio-controlled time
The time base for the radio-controlled time is a caesium atomic clock
operated by the Physikalisch Technische Bundesanstalt based in Braun-
schweig (Brunswick), Germany. 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 the frequency signal DCF-77 (77.5 kHz)
and has a transmitting range of approximately 1,500 km. Your radio
clock receives the signal, converts it and always shows the exact time.
The adjustment to Daylight Saving Time (summer/winter time) is auto-
matic. The reception quality depends mainly on geographic location.
Normally there should be no reception problems within a 1,500 km
radius around Frankfurt.
Therefore, please note the following steps:
• The recommended distance to any interfering sources like computer
screens or TV sets is at least 1.5 - 2 meters.
• Within concrete walls (reinforced with steel) such as basements, the
received signal is naturally weakened. In extreme cases, please place
the unit close to a window to improve reception.
• During night-time, the atmospheric interference is usually less
severe and reception is possible in most cases. A single daily recep-
tion is adequate to keep the accuracy deviation under 1 second.
