g) DCF time signal reception
The base unit automatically synchronizes the time and date, when it is within
the range of the DCF77 radio signal (within a radius of about 1500 km round
Frankfurt on the Main).
When the base unit receives a valid DCF signal, the manual time/date setting
is replaced by the automatic setting via the radio signal.
The icon indicating the DCF reception starts flashing, when the base unit
receives a DCF77 signal. Normally, it takes between 2 and 10 minutes,
depending on the signal strength, until the radio signal is completely received
and the time is displayed.
To disable the evaluation of DCF signal reception (for manual time/date
setting), press and hold the " " button for about 2 seconds, the icon for DCF
signal reception will disappear.
To enable the feature again, press and hold the " " button for about 2 seconds,
the icon for DCF radio signal reception will appear again, the base unit will
automatically search for the DCF signal. As mentioned above, it may take
between 2 and 10 minutes until the DCF time is displayed.
Strong Weak
Please note:
DCF signal reception can be affected by many factors. To achieve
the best reception, place the base unit away from metal objects
(e. g. heaters, metal doors) and electrical appliances (e. g. TV set,
computer, kitchen equipment).

8. Commissioning
Please note:
If you wish to operate more than one remote sensor, assign each
of them to a different channel (channel 1/2/3). Otherwise none of
them will function!
Insert the batteries first into the remote sensor and then into
the base unit.
When installing for the first time, place the base unit near the
remote sensor and then press the "RESET" button on the rear of
the base unit after you have inserted the batteries into the unit.
The transmission range between the remote sensor and the base
unit is usually about 20 to 30 m. But this strongly depends on the
ambient conditions around the unit (e.g. walls, reinforced concrete
ceilings etc.).
Please refer therefore to chapter "10. Ranges and radio
interference" on page 25 of these operating instructions.
Although the remote sensor is designed for outdoor installation and
operation, it has to be installed in protected locations, for example,
under a carport. Moreover, direct sunlight, rain, snow or the like
may negatively affect the measurement accuracy.
If you wish to mount the base unit or remote sensor on a wall,
depending on the composition of the wall, drill a hole in the wall and
insert a suitable wall plug.
When drilling, be careful not to damage by mistake any power
supply lines, gas or water pipes, as there may be danger of life
involved!
Insert a screw into the wall so that a
distance of about 3 mm is left
between the bottom part of the screw
and the wall. Later on, you can use
this screw, for attaching either the
base unit or the remote sensor.
