6.While the seconds digits are selected (flashing), press C to reset the seconds to “00”. If you press C while the seconds count is in the range of 30 to 59, the seconds are reset to “00” and 1 is added to the minutes. If the seconds count is in the range of 00 to 29, the minutes count is unchanged.
7.While the hour, minutes, year, month and date digits (besides seconds) are selected (flashing), press C to increase the number. Holding down C changes the current number at high speed.
8.After you finish making all the settings you want, press A to return to normal timekeeping.
•If you do not operate any button for a few minutes while a selection is flashing, the flashing stops and the watch goes back to the normal timekeeping automatically.
•The day of the week is automatically set in accordance with the date.
•The date can be set within the range of January 1, 1995 to December 31, 2039.
•When you use the above procedure to set the time on the digital display, the hands of the analog timepiece normally adjust according to your setting. If, for any reason, the analog time does not match the digital time, use the procedure described under Hand Setting Mode to match the analog setting with the digital display.
About daylight saving time
With daylight saving time (summer time), clocks are set one hour later in order to better take advantage of daylight hours during the summer, when days are longer. Whether or not daylight saving time is used depends on the country you are in.

TIME CALIBRATION SIGNAL
This watch is designed to receive the time calibration signal transmitted from Frankfurt, Germany. It automatically adjusts its current time setting in accordance with the signal it receives. There are two different methods you can use for signal receipt. With auto receive, the watch automatically receives the calibration signal twice each day and makes appropriate adjustments. You can also use manual receive, where you perform a specific button operation to receive the calibration signal.
•The current time setting in accordance with the calibration signal takes priority over any time settings you make.
•The watch is designed to automatically update the date and day of the week for the period January 1, 1995 to December 31, 2039. Setting of the date by the calibration signal cannot be performed starting from January 1. 2040.
•This watch can receive signals that differentiate between leap years and non-leap years.
How the analog hands react on the time calibration
After the watch successfully receives time calibration signal data, it automatically changes the settings of its hands. Before performing the time calibration operation, be sure to synchronize the digital time with the analog time using the procedures described under “Hand Setting Mode”. If not, the setting of the hands could result in being different from the digital time which is changed by the calibration signal.
Auto receive
When auto receive is switched on, the watch automatically receives the calibration signal starting from when the digital time reaches 2:00 AM and 4:00 AM each day. Calibration is performed regardless of what mode the watch is in, except when you are performing a data input or time setting operation (indicated by the flashing display). Use the following procedure to switch auto receive on and off.
To switch auto receive on and off
1.In the Timekeeping Mode, hold down A until the “On” or “OFF” message appears on the display.
2.Press C to switch auto receive on and off.
Press C
Receive indicator
Flashes when calibration signal is being received.
3. Press A to return to the Timekeeping display.
•Auto receipt of the calibration signal is designed to be performed early in the morning, while you sleep (provided that the digital time is set correctly). Before going to bed for the night, remove the watch from your wrist, and put it in a location where it can easily receive the signal. You should also orient the watch properly for best reception. See
“Tips for ensuring best reception” for details.
•Auto receive is switched on when the watch is shipped from the factory.
•The receive indicator appears on the display when the calibration signal is received successfully. It disappears from the display when the watch is unable to receive the signal for some reason. You can tell whether the last time the watch tried to receive the calibration signal was successful or not by checking the receive indicator.
How the auto receive time calibration is performed
•When auto receive is switched on, the watch receives the calibration signal for two to six minutes each day when the digital time reaches 2:00 AM and 4:00 AM (calibration times). Make sure you do not try to operate any of the watch’s buttons while the calibration signal is being received. Doing so can interfere with correct calibration.
•Remember that receipt of the calibration signal depends on the time shown on the digital display. The receive operation will be performed whenever the digital display shows 2:00 AM and 4:00 AM, regardless of whether or not that is actually the correct time.

•When both receipts are successful, the watch uses the data of the second receipt for calibration. When only one receipt is successful, the watch uses the data of the successful receipt.

Manual receipt
While in the Timekeeping Mode, hold down C for three or four seconds.
• When performing reception of the calibration signal, make sure that the antenna located at the 12 o’clock edge of the watch is facing in the proper direction. See “Tips for ensuring best reception” for details.
•The normal timekeeping display should appear within two to six minutes, which is how long it takes for a signal receive operation. If a problem occurs during the operation, the message “Err” appears on the display for about five seconds before the watch returns to normal timekeeping.
•The receive indicator appears on the display when the receive operation is concluded successfully.
•You can interrupt a receive operation at any time by pressing C. If you do, the watch returns to normal timekeeping, without the receive indicator on the display.
Last signal receipt display
Holding down B for a few seconds in any mode displays the date and time of the last successful receipt. Press any button to return to normal timekeeping. The watch automatically changes back to normal timekeeping if you do not press any button for about 10 seconds.

Tips for ensuring best reception
< Location >
•Reception of the calibration signal is difficult when the watch is located indoors. Move the watch so it is as near to a window as possible.
•The followings are locations where reception is bad.
Nearby TVs, refrigerators, computers, or other household appliances
Far away from broadcasting stations, among ferro-concrete structures or near mountains
Underground, in tunnels or in ferro-concrete buildings
Near high-tension wires, neon signs, or radio stations whose frequencies interfere Near railroads, highways or airports
In trains or cars
< Orientation >
This watch is designed to receive a signal emitted from Mainflingen, which is located 25 kilometers southwest of Frankfurt, Germany. This means that reception is best when the antenna built into the 12 o’clock edge of the watch is facing towards Mainflingen. Note, however, that moving the watch while the calibration signal receive operation is taking place will make stable reception impossible.
Antenna built in here
Point towards Mainflingen
P
Reception range
This watch is able to receive the calibration signal within the area represented by a circle (left figure) with a radius of 700 ~ 800 kilometers, centered on Mainflingen.
•Signal reception is affected by weather, atmospheric conditions, and seasonal changes.
Note
• |
Even when the watch is within the reception range, |
|
|
calibration signal reception will be impossible if the |
|
|
signal is blocked by mountains or other geological |
|
|
formations between the watch and signal source. |
|
• |
At long distances that are out of the line of sight of |
|
Frankfurt |
the calibration signal transmitter, the calibration sig- |
|
nal is bounced off of 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 atmospheric changes or the time of day may change the reception range of the signal and make reception temporarily impossible.
TELEMEMO MODE
