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.

Ensure that the correct 12 hour cycle is selected.
3. After setting the time, the CR9931 will continue to run on its own
internal time memory and will automatically synchronise itself with
the radio time signal commencing at 00:00, 01:00, 02:00, 03:00 and
04:00.

clock radio to the position giving best reception.
