ABOUT RADIO RECEPTION

The RM822 / RM823 is a radio frequency (RF) controlled clock. When located within a 1500km radius of radio signal (DCF77) at Frankfurt, Germany, the clock time will automatically synchronize with DCF77 time-signal transmission. The benefit of a RF controlled clock is that highly-accurate time is maintained and manual adjustments to the time and date are not be required.

(UK version within a 1500km radius of radio signal (MSF) from Rugby, England)

When the batteries are first installed, the RM822 / RM823 will automatically search for a radio signal.

When in search mode, the antenna icon []will blink. This process takes between two (2) and ten (10) minutes. After initial search, short periodic reception signal scans will commence several times a day.

The antenna icon indicates the quality of reception.

To enable the RF function:

Press []and hold for 3-seconds. The radio-reception signal will appear and a signal search will automatically commence.

Interference

Reception can be affected by a number of factors. For best reception, place the device away from metal objects and electrical appliances.

Note: Interference from sources such as TV sets can affect the signal. If, after batteries have been inserted for ten minutes, the signal is not received, then set the time manually (see section: How To Set The Calendar Clock Manually).
