ABOUT RADIO RECEPTION
The JM828CD is designed to automatically synchronize its calendar clock once it is brought within range of the Frankfurt
DCF77 radio signal [UK version, Rugby (radio signal MSF)].
When the JM828CD is within range, the radio-control mechanism will override all manual settings.
Upon receiving a radio signal, the Radio Reception Icon will start
to blink. Generally, complete reception take 2 to 10 minutes
depending on the strength of the radio signal.
When the reception is complete, the Radio Reception Icon will
stop blinking.
For better reception, place the clock away from metal objects and
electrical appliances to minimize interference.
