ABOUT RADIO RECEPTION
The RRM-112 is designed to automatically synchronize its
current time and date when brought within range of the DCF77
RF signal.
(UK version within a 1500km radius of radio signal (MSF) from
Ruby, England)
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.
When the reception is completed the reception icon will stop
blinking. The reception icon will show " " for no Reception or
" " for successful reception.
For better reception of radio signals, place the clock away from
metal objects and electrical appliances to minimize interference.
Note: The radio reception of the calendar clock will be ceased
automatically during the radio is turned on. When the radio is
turned off, the clock will enable auto-reception again.
