The CR950 receives the sycronisation signal from one of the most
accurate clocks in the world. The signal is transmitted from the official UK
standard frequency and time signal transmitter MSF located at Rugby in

How to Optimise the Time Signal Reception
After setting the time, the CR950 will continue to run on its own internal
quartz time base and will automatically synchronise itself with the radio
timesignalcommencingonthe54thminuteofeveryhour. Oncesynchro-
nisation is achieved the time and date of the radio time signal will be
restoredanddisplayed.
Thetimesettingorsynchronisationtakes2to3minutestocompleteifthe
reception of the radio time signal is undisturbed. This process will take
longer if the time signal level is very weak (e.g. in locations that are a long
distance from the MSF transmitter) or if it is subject to interference from
thunderstorms, nearby TV sets, computers or household appliances that
arenotsuppressed,etc.).IngeneraltheCR950willreceivethetimesignal
at any place where a radio is able to receive Long Wave broadcast
programmeswell.
Note: Pressing the forward or reverse buttons once will cause the display
to increment by one. Press and hold down the forward or reverse buttons
to rapidly increment the display.
The CR950 receives the time signal via its built-in ferrite aerial which is
directional.
