As soon as the batteries are inserted, the alarm
clock switches to reception, see next chapter.
Notes on changing the battery:
Only use the battery type specified in the
"Technical Data".
Always exchange all of the batteries at the
same time.
Dispose of old batteries in an environmentally
friendly manner, see "Disposal".
Receiving the time signal
When the batteries are inserted, all displays are shown
for a brief moment and the display is illuminated.
The measured room temperature is displayed
shortly afterwards.
The device then switches to receiving-
mode, during which the number of
radio waves indicates the quality of the
reception: The more radio waves shown
on the display, the better is the reception.
As soon as the time signal has been received in
sufficient strength, the time is displayed. The radio-
controlled alarm clock automatically switches to
reception several times every night. During this
process, the displayed time is compared with that
received from the time signal transmitter and, if
necessary, corrected.
