RECEPTION OF RADIO CONTROLLED SIGNAL
This clock includes a built-in receiver which picks up the signal from the DCF station.
Therefore, the clock automatically sets the time, date and weekday.
● The clock automatically carries out four periodic synchronization procedures (at 2:00 AM,
8:00 AM, 2:00 PM and 8:00 PM daily) with the RC signal to correct any deviations to the
exact time.
● Once the unit synchronizes successfully to the RC signal, the signal icon
“ ”
will show
up. Each synchronization process will take between 6 to 16 minutes.
● To manually start the signal reception, press
[ RCC ]
button once or press and hold it
for 3 seconds in order to stop the reception.
Note:
● The strength of radio-controlled time signal from the transmitter tower may be
affected by geographical location or building around.
● Always place the unit away from interfering sources such as TV set, computer, etc.
● Avoid placing the unit on or next to metal plates.
● Closed areas such as airport, basement, tower block, or factory are not
recommended.
SIGNAL RECEPTION INDICATOR
The signal indicator displays signal strength in 4 levels. Wave segment flashing means time
