TIME CALIBRATION SIGNAL RECEPTION PRECAUTIONS Mainflingen 1200 km · This clock is able to receive the time calibration signal transmitted from Mainflingen, Germany (located 25kilometers southeast of Frankfurt). Signal reception is possible within approximately 1,200 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 500 km range of the signal and make reception temporarily impossible. · Reception is best when the back of the clock is facing toward Mainflingen. 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. Manual Receive 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. 2 Operation Guide DQR-300 Setting the Time and Date Manually Turning the Alarm On and Off Use the Alarm Mode selector (5) on the side of the clock to turn the alarm on and off, and to select the snooze feature. Alarm Mode selector SNZ Description The alarm sounds at the preset time for one minute, and seven more times every five minutes thereafter.
