ABOUT RADIO RECEPTION
The IBR923 is designed to automatically synchronize its calendar
clock once it is brought within range of the Frankfurt DCF77 radio
signal. It will scan and adjust every full hour.
When the unit is within range, its radio-control mechanism will
override all manual settings.
When the unit is receiving radio signal, the RADIO RECEPTION
signal will start to blink. A complete reception generally takes about
two to 10 minutes, depending on the strength of the radio signal.
