ABOUT RADIO RECEPTION
hour, minute, and second mode
The JM828WF is designed to automatically synchronize its current time and date when brought within range of the DCF77 or the MSF60 (Model JM828WFU) RF signal.
When the unit is within range, its radio-control mechanism will override all manual settings.
When the unit is receiving radio signal, the reception icon will start to blink. The reception icon will show either strong, weak or no signal depending on the strength of the radio signal. A complete reception generally takes about two to 10 minutes.
