TIME CALIBRATION SIGNAL RECEPTION PRECAUTIONS

•This clock is able to receive the time calibration signal transmitted from

Rugby, England. Signal reception is possible within approximately

1,000 kilometers

Rugby

1,000 km of the transmitter.

 

 

•Even when the clock is within the reception range, signal reception is impossible if the signal is blocked by mountains or other geological formations between the clock and signal source.

•Signal reception is affected by weather, atmospheric conditions, and

seasonal changes.

• The time calibration signal is bounced off the ionosphere. Because of this, such factors as changes in the reflectivity of the ionosphere, as well as movement of the ionosphere to higher altitudes due to seasonal atmosaheric changes or the time of day may change the reception range of the signal and make reception temporarily impossible.

•Reception is best when the back of the clock is facing toward Rugby.

Note, however, that moving the clock while the time calibration signal receive operation is taking place will make stable reception impossible.

•Think of the clock as acting like a TV or radio when it is receiving the calibration signal.When receiving indoors, move to a location as near as possible to a window. Proper signal reception can be difficult or even impossible under the conditions listed below.

•Signal reception is normally better at night than during the day.

•Radio interference can make signal reception impossible.

•Strong electrostatic charge can result in the wrong time being set.

•The alarm does not operate during signal reception.
