TIME CALIBRATION SIGNAL RECEPTION PRECAUTIONS

•This clock can receive the time calibration signals transmitted from Mainflingen, Germany and Rugby, England. It automatically selects reception from the transmitter whose signal is strongest.

Mainflingen: Signal reception is possible within approximately 1800 km of the transmitter.

Rugby: Signal reception is possible within approximately 1800 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

Mainflingen

atmospheric changes or the time of day may change the reception range

1,800 kilometers

of the signal and make reception temporarily impossible.

 

•Reception is best when the back of the clock is facing in the direction of the transmitter. As a general rule, point the back of the clock towards the transmitter that is closest to your location. If you experience reception problems, try pointing it in the direction of the other transmitter. 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.

USING THE CLOCK 1

This clock can receive the time calibration signals transmitted from Mainflingen, Germany and Rugby, England. It automatically selects reception from the transmitter whose signal is strongest.

Any of the following procedures can be used to set current date and time.

•Auto receive of the time calibration signal

•Manual receive of the time calibration signal

•Manual setting without using the time calibration signal

Auto Receive

•This clock performs a 1-minute receive operation each hour.

•A signal receive operation takes from two to fourteen minutes under good signal conditions.

•As the clock receives a time calibration signal, current signal strength is indicated by the receive indicator, which is a horizontal line above the current time.

•A longer receive indicator line means better signal reception.

Antenna Icon

The antenna icon appears when at least one signal receive operation is successful during a day. The antenna icon is cleared at 2 a.m. and 3 a.m. each day, and will reappear as soon as a subsequent signal receive operation is successful.

Wave OK Indicator

The Wave OK indicator is displayed when there has been a successful receive operation within the last hour. This indicator disappears at the top of each hour, or when you perform a manual receive operation.

Unsuccessful Signal Reception

The antenna icon disappears from the display if no signal receive operation is successful during a continuous 24-hour period. If this happens, try changing the position or orientation of the clock, and press the WAVE button (8) to receive again.

Manual Receive

•Press the WAVE button (8) to start a calibration signal receive operation.

•Use the WAVE button (8) to perform a receive operation after replacing the clock’s batteries or if the auto receive operation was not performed correctly for some reason.

•The antenna icon appears when signal reception triggered by the WAVE button (8) is successful.

Important!

•Do not perform any button or switch operation while a signal receive operation is in progress.

•The time calibration signal includes both Standard Time and Daylight Saving Time (summer time) data.

•The DST indicator appears on the display when Daylight Saving Time (summer time) data is received.

•Note that Daylight Saving Time (summer time) is turned on and off in accordance with the received time calibration signal only. You cannot turn it on or off manually.
