Precision Retro Radio Controlled Alarm Clock Instruction manual

AP043 - Instruction Manual

The Radio-Controlled Clock

With the Radio-Controlled Clock, you can have the most accurate time within the UK. It can receive the time signal transmitted by VT Communications of United Kingdom, which is regulated by atomic clock and in average deviates less than 1 second in 10 million years. VT Communications transmit the time signal (MSF 60kHz) continuously from Anthorn at latitude 54°55′N and longitude 3°15′W. The main caused of reception difficulties are local interference and screening due to nearby metalwork, for example in a steel-frame building.

For more information, please study the WEB page of VT at: http://www.npl.co.uk/time/msf.

Environmental Reception Effects

The Radio-Controlled Clock obtains the accurate time with wireless technology. As with all wireless devices, the receiving ability may be affected by, but not limited to, the following circumstances:

* Long transmitting distance.

* Nearby mountains and valleys.

* Among tall buildings.

* Near railway, high voltage cables, etc.

* Near motorway, airport, etc.

* Near construction site.

* Inside concrete buildings.

* Near electrical appliances.

* Near computers and televisions.

* Bad weather.

* Inside moving vehicles.

* Nearby metallic structures.

Location precautions

This clock receives a radio wave much like a TV or radio. Be sure to locate it near a window or some other locations where reception is good. Avoid the following locations, which can interfere with proper reception:

Inside or near concrete/steel buildings Next or close to power station. In moving vehicles (cars, trains, airplanes etc.) or structures, unless the clock is close/ where radio transmission or electronics may interfere, next to a window (with curtain open). with reception of the radio-controlled clock.

Too close to household appliances

(computer, TV, video/audios, fax machines, speakers).

Near construction sites, traffic lights, neon lights etc.

Close to or on top of metal

B. BATTERY INSTERTION

Place one 9V battery into battery compartment for back-up purposes in case of power failure.

The LED display will not light but alarm will ring when reaches alarm time.

It is advised the back-up battery should be fitted to maintain time and settings.

National Physical Laboratory

The National Physical Laboratory (NPL) is the UK's home of measurement and the nation's timekeeper. NPL is responsible for operating the national time system and making accurate time available across the UK. The clock you have just received keeps accurate time by picking up NPL's radio signal, called MSF, which is broadcast on 60 khz from a location in Cumbria. This transmission carries a date and time code that radio controlled clocks use to set themselves to the correct time.

The signal is controlled by atomic clocks at the radio station, and is adjusted to keep it in step with the national time maintained at NPL's laboratory in south-west London. For more information visit www.npi.co.uk/time Your clock is controlled by the MSF signal which is synchronised to the national time scale at NPL, making it ‘forever a
