Time Calibration Signal Reception
This watch is designed to pick up a time calibration signal transmitted from
Mainflingen, Germany and update its time setting in accordance with the signal. There
are two different methods you can use to receive the signal: Auto Receive and
Manual Receive. With Auto Receive, the watch automatically receives the calibration
signal three times each day and makes appropriate adjustments. With Manual
Receive, you perform a specific button operation to receive the calibration signal.
Note
•If you are using the time calibration signal to set the time for this watch, be sure to
correctly set your home city. Otherwise, there is the chance that the watch will not
set the correct time. See the “To select your Home City code”for details.
•This watch automatically switches between DST and standard time while BER is
selected as the home city code. For any other home city code, you must perform the
procedure under “To set the current time and date manually”to switch between DST
and standard time.
•Time calibration reception is limited to specific geographic areas in West Europe.
•The current time setting in accordance with the time 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, 2000 to December 31, 2039. Setting of the date by the time
calibration signal cannot be performed starting from January 1, 2040.
•This watch can receive signals that differentiate between leap years and non-leap years.
•Auto Receive is turned on when the watch is shipped from the factory.
•See the information under “Time Calibration Signal Reception Precautions”
if you experience problems with time calibration signal reception.
To perform manual time calibration signal reception
1. Place the watch on a stable surface to its top (12
o’clock side) is facing in the general direction of
Frankfurt, Germany.
•This puts the watch in the optimum position for time
calibration signal reception.
2. In the Timekeeping Mode, hold down Dfor about two
seconds, until the watch beeps.
•At this time, the indicator on the watch’s display
should scroll from left to right, which indicates that
signal reception has started.
•Time calibration signal reception takes from four to 11
minutes. Take care that you do not move the watch
during this time.
•After signal reception is complete, the display of the
watch changes to the Last Signal screen, which
shows the new signal receive date and time.
Current time

Note
•To interrupt a receive operation and return to the Timekeeping screen, press D.
•If the receive operation is unsuccessful, the message “ERR”appears on the Last
Signal screen for about one or two minutes. After that, the watch returns to the
Timekeeping screen.
•You can also change from the Last Signal screen to the Timekeeping screen by
pressing D.
About the Receive Indicator
The receive indicator shows the strength of the calibration signal being received. For
best reception, be sure to keep the watch in a location where signal strength is
strongest.
•Even in an area where signal strength is strong, it takes about 10 seconds for signal
reception to stabilize enough for the receive indicator to indicate signal strength.
Weak Strong

USER’S GUIDE 2506

•Use the receive indicator as a guide for checking signal strength and for finding the
best location for the watch during signal receive operations.
•The receive indicator remains on the display in all modes following reception of the
time calibration signal and calibration of the watch’s time setting. The receive
indicator does not appear if signal reception was unsuccessful or after manual
adjustment of the current time setting.
About Auto Receive
When auto receive is turned on, the watch automatically starts to receive the time
calibration signal when the digital time in the Timekeeping Mode reaches 2:00 AM,
4:00 AM, and 6:00 AM each day (calibration times).
Note
•The Auto Receive operation is performed only if the watch is in the Timekeeping
Mode or World Time Mode when one of the calibration times is reached. It is not
performed if the calibration time is reached while you are making settings (while
settings are flashing on the 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.
•The receive indicator ( ) indicates that one, two, or all three of the last calibration
time reception attempts were successful.
•When auto receive is turned on, the watch receives the calibration signal for four to
11 minutes each day when the digital time reaches 2:00 AM, 4:00 AM, and 6:00 AM.
Do not operate any of the watch’s buttons within 15 minutes prior to or following the
calibration times. Doing so can interfere with correct calibration.
•Remember that reception 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, 4:00 AM, and 6:00 AM, regardless of whether or not the displayed
time is actually the correct time.
•When two or three receptions are successful, the watch uses the data of the last
reception for calibration. When only one reception is successful, the watch uses the
data of the successful reception.
To turn auto receive on and off
1. In the Timekeeping Mode, hold down Auntil the
current Auto Receive On/Off setting starts to flash,
which indicates the setting screen.
2. Press Dto toggle Auto Receive on (ON) and off
(OFF).
3. Press Ato exit the setting screen.

Time Calibration Signal Reception Precautions
•This watch is able to receive the time calibration signal
transmitted from Mainflingen, Germany (located 25
kilometers southeast of Frankfurt). Signal reception is
possible within the area represented by a circle with a
radius of about 800 kilometers.
•Even when the watch is within the reception range,
signal reception is impossible if the signal is blocked by
mountains or other geological formations between the
watch 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 atmospheric changes or the time of
day may change the reception range of the signal and make reception temporarily
impossible.
•This watch is designed to receive the signal transmitted from Mainflingen. 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
time calibration signal receive operation is taking place will make stable reception
impossible.
•Think of the watch 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.
Near 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 with interfering frequencies
Near railroads, highways or airports
In trains or cars
•Radio interference can make signal reception impossible.
•Strong electrostatic charge can result in the wrong time being set.
•The daily alarm and hourly time signal do not operate during signal reception.
•If you are in an area where proper time calibration signal reception is impossible, the
watch keeps time within ±15 seconds a month at normal temperature.

Troubleshooting
Check the following points whenever you experience problems with your watch.
Problem
Cannot perform
manual receive.
Auto receive is
turned on, but
the receive
indicator does
not appear on
the display.
Time setting is
incorrect
following signal
reception.
Probable Cause
The watch is not in the Timekeeping Mode.
•You changed the time setting manually.
•The watch was not in the Timekeeping
or World Time Mode or you were
performing some button operation
during the last auto signal receive
operation was perfor med.
• The receive indicator does not appear if a
single receive operation is not successful.
Even if receive is successful, the receive
indicator disappears every day at 3am.
• If the time is one hour off, DST is turned on.
•The Home City Code setting is not
correct for the area where you are using
the watch.
What you should do
Enter the Timekeeping Mode
and try again.
•Wait perform manual signal
receive or wait until the next
auto signal receive operation
is performed.
•Check to make sure the watch
is in a location where it can
receive the signal.
• Put the watch in a location that
is suitable for good reception.
•Turn off DST.
•Select the correct Home City
Code.
WorldTime
•The current time in all World Time Mode cities is calculated in accordance with the
Greenwich Mean Time (GMT) differential for each city, based on the current Home
City time setting in the Timekeeping Mode.
•GMT differential is calculated by this watch based on Universal Time Coordinated
(UTC) data.
Backlight Precautions
•The electro-luminescent panel that provides illumination loses power after very long use.
•The illumination provided by the backlight may be hard to see when viewed under
direct sunlight.
•The watch may emit an audible sound whenever the display is illuminated. This is
due to vibration of the EL panel used for illumination, and does not indicate
malfunction.
•The backlight automatically turns off whenever an alarm sounds.
