5. Radio technology
Radio technology is the most modern form of time transmission. With
good reception, a radio-controlled clock keeps very precise time and
need never be reset. With all radio-controlled clocks a deviation of just
1 second over 1 million years can be expected.
6. Commissioning
Your radio-controlled wall clock is operated with one 1.5 V LR 6 alkaline
mignon battery.
1. Insert the battery in accordance with the polarity marking.
2. As soon as your radio-controlled wall clock is supplied with power, it
is ready for operation.
3. Reading of the time telegram is fully automatic.
Once the battery is inserted, all hands move in overdrive to the
12 o'clock position. Once the radio signal is successfully received,
the hands will automatically be set to the current time. The clock
calibrates itself several times daily with the DCF-77 radio signal.
7. Manual time setting
Hold down the 'M Set' button on the rear of your radio-controlled wall
clock for longer than 3 seconds. By pressing the button now, you can
advance the clock to the right time in minutes. It is not possible to set
the seconds function manually. If the 'M Set' button is not pressed wit-
hin 7 seconds, the function is concluded and your clock will now conti-
nue to run as a quartz clock. When the clock is once again located
within the radio reception range of the DCF-77 transmitter, the hands
will automatically synchronise with the current time.
