This radio controlled clock by St Helens Home Garden is supplied in an attractive white finish with a numerical dial. The radio controlled function means that the time on this clock is automatically set by a time code transmitted by a radio transmitter, this guarantees that the clock will always display the time accurately and will automatically update in Spring when the clocks go forward by one hour and in Autumn when the clocks go back by one hour. This clock can only be used in the UK and Ireland. Radio controlled clocks will only operate in buildings where the UK time code signal can penetrate. Metal clad buildings or those with re-enforced concrete are unlikely to be suitable for this product. In order to set the clock, hold either the Rec or Reset button located on the back of the clock for at least 5 seconds; release the button and then allow approximately 10 minutes for the clock to automatically set itself to the correct time.
