Automatic clock setting  
When you plug in your clock radio for the first time it will receive and synchronise to the official UK standard frequency and time signal transmitter  
(MSF) located at Rugby in the U.K.  
At certain times of the year the MSF transmitter closes down for maintenance during this time it will be necessary to set the clock  
manually (see the sections headed Setting the time manually). Recorded information on transmitter status can be obtained on 020 8943  
6493.  
Your clock radio will only need to be set manually if the transmitter is closed down when your clock radio is first connected to the mains.  
At all other times if the transmitter closes down, your clock radio will continue to run on its own internal time memory.  
Switching on  
1. Place the unit on a flat surface. Plug the mains lead into a wall socket  
and switch on.  
2. The built in microprocessor will automatically activate the Radio  
Controlled clock and initiate a search for the time signal. The MSF  
indicator will flash whilst the time is being set.  
3. When your clock radio is receiving the radio time signal, the seconds’  
digits will appear in the display.  
4. When the time setting process has been completed (2-4 minutes),  
the exact time will appear in the display. The MSF indicator will stop  
flashing.  
5. If the time does not set it may be necessary to rotate your clock  
radio to a position giving better reception of the MSF signal.  
6. It is recommended that your clock radio is placed as far away as  
possible from any sources of interference such as computers or  
televisions, etc.  
7. Your clock radio can be made to re-synchronise with the radio time  
signal by pressing and releasing the Time button until the MSF  
indicator begins to flash. Syncronisation is complete when the MSF  
indicator stops flashing.  
In the event of a mains power failure your clock radio will  
automatically synchronise with the MSF time signal and reset  
the clock when the mains power is restored.

3. After setting the time, the CR9931 will continue to run on its own  
internal time memory and will automatically synchronise itself with
