About the Time Signal

Set the time manually

If the clock is located out of range of a transmitter or radio signal reception is not
possible, you can set the time manually.
1. Keep the M.SET button pressed until the second hand stops turning.
2. Press the M.SET button again. The hands begin to turn.
3. Release the button shortly before the correct time is indicated.
4. Briefly and repeatedly press the M.SET button in order to set the clock to the correct
time. With each tap the time is set forward by one minute.
When M.SET is not pressed for 8 seconds, the currently set time is stored
and you have to repeat the process.

Resetting the clock to factory settings

If the incorrect time is repeatedly indicated, you can reset the clock to factory settings
(reset function). A reset is required only in exceptional cases.
− Using a thin object (e.g. an unwound paperclip) press down on the RESET button.
The clock hands turn to 12:00 o'clock, the clock then switches to receiving mode.
About the Time Signal

General information

This radio wall clock obtains its radio signal from the DCF77 time signal transmitter.
This broadcasts the precise and official time of the Federal Republic of Germany on the
long-wave frequency of 77.5 kHz.
The transmitter is located in Mainflingen near Frankfurt am Main and, with its range of
up to 2000 km, supplies the majority of radio-controlled clocks in western Europe with
the necessary radio signals.
Once the clock is energised, switches to the receiving mode and searches for the
signal from the DCF77 transmitter. If the time signal has been received with sufficient
strength, the hands set themselves to the correct time.
The clock switches on multiple times daily and synchronises the clock time with the
radio signal from the DCF77 transmitter. In the event the signal is not received, e.g.
during a strong storm, the device continues to run precisely and then switches to
receiving mode again at the next scheduled time.
