The radio controlled mechanism fitted to your clock

The radio controlled mechanism fitted to your clock
The radio controlled mechanism fitted to your clock has a built in receiver which is tuned to the National Physical
Laboratory (NPL) radio signal, called MSF, which is transmitted from the Anthorn radio station in Cumbria. The MSF signal
is broadcast on a frequency of 60khz and carries a time and date code that radio controlled clocks use to set themselves
to the correct time. The time signal received is controlled by cesium atomic clocks and is accurate to within one second
every 1000 years.
Interruption to the MSF signal
The Anthorn transmitter is periodically shut down for scheduled maintenance resulting in no signal being transmitted.
For dates of the schedule maintenance visit
products-and-services/msf-outages or call the NPL MSF recorded message on (0)20 8943 6493.
MSF reception difficulties
Like any receiver your clock needs a good signal to work properly. The main causes of reception failure are...
- Atmospheric and local interferences.
- Interference from electrical equipment e.g. T.V, computers or radios within 2 meters of the clock.
- Location of the clocks internal receiver within the building.
- Reduced local signal due to steel framed structure. Reduced signal due to interference problems in your house or building.
- Outside the normal transmission radius.
Problem - The clock will not receive Radio Controlled signal and will not set to the correct time.
Solution - Check the batteries are new and in good condition.
- Check that the batteries are inserted correctly.
- Try rotating the clock as the internal receiver that picks up the signal is most effective when it is facing directly towards
or away from Anthorn.
- Try moving your clock to a new location away from any electrical equipment, e.g. T.V. computers or radios.
- Remove the batteries and insert the batteries again after 5.30pm. Due to local interference the signal is stronger
between midnight and 5am.
- Manual set (see page 1).
Problem - Your clock chimes incorrectly.
Solution - Change the batteries and reset your clock following the instructions on page 1.
Problem - Your clock will not chime.
Solution - Change the batteries and reset your clock following the instructions on page 1.
Problem - The clock loses time.
Solution - Insert a new battery and reset the clock following the instructions on page 1.
Note. When the clock receives the signal, to maintain accuracy it will search for the signal every second hour starting
at 1 o'clock, 3 o'clock, 5 o'clock...
Problem - What do I need to do when the clocks change for Summer/Winter time?
Solution - Nothing!
- The clock will automatically switch to the correct time when the time signal is received. The chime movement
will then adjust automatically to the correct Chime sequence when the minute hand reaches at 12 o'clock position.
- It is recommended that you replace the batteries annually, even if the product is still running.
- Do not mix new and used batteries, different types or brands.
- Only use AA (1.5V) Alkaline batteries in this clock.
- Please dispose of used batteries in responsible manner.
A soft cloth may be used to clean your clock. Do not use any corrosive cleaner or chemical solutions on the clock. Keep the clock
clean and dry to avoid any problems.
