SET DEMO RESET WAVE 1 Operation Guide DQD-70B TIME CALIBRATION SIGNAL RECEPTION PRECAUTIONS Rugby 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 (6) to receive again. · Press the WAVE button (6) to start a calibration signal receive operation. · Use the WAVE button (6) 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 (6) is successful. · 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. 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. 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. Setting the Time and Date Manually · When using the clock in an area that is outside of the range of the transmitter or in an area where signal reception is impossible for some reason, you need to manually adjust the time setting as required. 1. Press the SET button (3) to cycle through the setting screens as shown below. Current Time Screen GMT Differential Setting Screen Contrast Adjustment Screen Inside, among buildings, or near neon signs Inside a vehicle Near refrigerators or other household appliances, near office equipment, mobile phones or wireless LAN devices. Near a construction Near high-tension site, airport, or other power lines sources of electrical noise, underground or in tunnels, near railroads, highways, or radio stations with interfering frequencies. Among or behind mountains Year Setting Screen Month and Day Setting Screen Time Setting Screen 12-hour/24hour Setting Screen · 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 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. 2 Operation Guide DQD-70B 2. While the screen you want is on the display, use the Alarm Time Set buttons (7) to change the digits that are flashing. · Holding down + or ­ changes the flashing digits at high speed. · Your GMT differential is a value that indicates the time difference between your current location and Greenwich Mean Time (GMT). You can find out the GMT differential of your location by checking the nearby map. · You can set the year in the range of 2000 to 2099. The day of the week is set automatically in accordance with the date setting. · Pressing + or ­ while the Time Setting Screen is on the display causes the seconds count to be reset to 00. · Each press of + or ­ while the 12-hour/24-hour Setting Screen is on the display toggles between 12-hour and 24-hour timekeeping. · You can select one of 16 levels for the contrast setting. Select the setting that makes the display easy to read. 3. After making the settings you want, use the SET button (3) to display the Current Time Screen. · The clock automatically returns to the Current Time Screen if you leave a setting screen on the display for about three minutes without performing any operation. BATTERY REPLACEMENT Press + to increase the flashing digits. Press ­ to decrease the flashing digits. GMT differential : 0H : 1H : 2H : 3H Replace batteries whenever the display of the clock becomes dim and difficult to read. 1. Open the battery compartment cover as shown in the illustration. 2. Remove both of the old batteries. 3. Load two new batteries. Make sure that their positive (+) and negative (­) ends face in the correct directions. If you load batteries incorrectly, they can burst and damage the clock. 4. Press the RESET button (5). Be sure to press the RESET button (5) after replacing batteries. 5. Replace the battery compartment cover. Battery precautions · · · · · · · Keep batteries out of the reach of small children. If a battery is accidentally swallowed, contact your physician immediately . Be sure to load the batteries with their positive (+) and negative (­) ends facing correctly. Never mix old and new batteries, or batteries of different brands. Never charge the batteries that come with the clock. Should batteries ever leak while in the clock, wipe out the fluid with a cloth, taking care not to let any get onto your skin. Replace the batteries at least once a year, even if the current batteries are working properly. The batteries that come with the clock lose some of their power during transport and storage.
