INITIAL COMMISSIONING:
When all batteries are inserted in the main unit, all display segments are briefly visible on the screen
and a signal tone sounds.
The temperature and humidity values d etermined by the main unit are then displayed. The appears in
the text field
Indication "INDOOR" and in the area of t ime and date tums are shown at the beginning 00:00:00 and
Indication "INDOOR" and in the area of t ime and date tums are shown at the beginning 00:00:00 and
01.01.10 (the device counts up the time until the DCF signal has been received or the time and date
have been set manually).
In the first 3 minutes after starting up the main unit, the system searches for outdoor transmitters. After
changing the battery, previously added transmitters are automatically assigned to the previous channel
during this period. Previously unknown transmitters are automatically added to channels that may still be
free.
RADIO CONTROLLED DCF-77 RECEPTION
After the main unit has finished searching for broadcasters after 3 minutes, the unit starts searching for
the DCF signal (radio clock signal) and the DCF reception signal flashes. When the time code has been
received after 5-10 minutes, the radio controlled time is displayed and the DCF reception signal remains
on the LCD.
If the radio clock cannot receive a DCF signal (e.g. due to interference, transmission
•
distance, etc.), the time can be set manually.
The clock then works like a normal quartz clock (see: Manual time setting).
•
The radio clock receives the DCF signal at 2:00 and 3:00 a.m.
•
As soon as the radio clock can receive a signal, the manually set time is overwritten.
•
Please note that communication with the USB radio transceiver is not possible during
•
radio clock reception and may be briefly interrupted.
