One of the most accurate and reliable kinds of alarm clocks are ones that are synchronised with a radio signal, most major countries have a national radio signal which transmit’s the correct time. By synchronising with this signal means that you do not need to set the time and it automatically adjusts for any British summertime changes.
The benefit of having an clock which sets it’s time automatically is that you do not have to worry about making sure the correct time is displayed, this gives you peace of mind as well as knowing that when you have to wake up in the morning the alarm will go off at the time set, not before or after.
The UK’s national radio signal is transmitted from Cumbria, and this signal’s time is synchronised with the UK’s national atomic clock, which is extremely accurate and reliable. When you buy a new radio controlled clock it will search for this signal and set the time according to it. If the batteries run out or electricity is not supplied for a moment, when it next goes on again the alarm will once again reset the time so its accurate.
One of the best features of radio controlled alarms is that they also correctly adjust the time when the clocks go forward each year, as well as when the time go back each year.
Most RC clocks have digital displays, but some have the old analogue clock face to tell the time. They tend to be more expensive than most normal alarms, due to the electronics required to synchronise and set the time. Many modern versions also have extra features built into the clock, such as temp display, radio, Ipod docking stations and a multitude of other great features.
The range comes in all sizes, colours and styles with most of the UK’s alarm clock suppliers providing a wide range to cater for all tastes and preferences.
