Note: Led H1 (seconds) is located at the top, H10 (days) at the bottom!
The time is synchronized (time of day setting) via antenna using the DCF-77
radio signal. This signal can be received in Central Europe.
A differentiation is made between the following antennas:
• antenna for inside installation
• antenna for outside installation
The antenna must be aligned so that optimum reception is guaranteed.
Generally, this is towards Frankfurt/Main, where the signal transmitter is
located. The BNC socket X7 at the front panel is used to connect the
antenna.
