time setting accordingly. The time calibration signal includes both Standard Time and
Daylight Saving Time (summer time) data.
Current Time Setting
This watch automatically adjusts its time setting in accordance with a time calibration
signal. You can also perform a manual procedure to set the time and date, when
necessary.
• The first thing you should do after purchasing this watch is to set your Home City,
which is the city where you will normally use the watch. For more information, see

City code. If it does not, it should adjust automatically after the next auto receive
operation (in the middle of the night). You can also perform manual receive (see "To
perform manual receive") or you can set the time manually (see "Setting the Time
and Date Manually").
• If you are in an area that does not use Daylight Saving Time (summer time), turn off
the DST setting (see "To change the Daylight Saving Time (summer time) setting").
Time Calibration Signal Reception
There are two different methods you can use to receive the time calibration signal:
auto receive and manual receive .
• Auto Receive
With auto receive, the watch automatically picks up the time calibration signal three
times a day at 2:00 AM, 4:00 AM, and 5:00 AM. For more information, see "About Auto
Receive".
• Manual Receive
Manual receive lets you start a time calibration receive operation with the press of a
button. For more information, see "To perform manual receive".
Important!
• Position the watch as shown in the nearby illustration, with its 12 o'clock side facing
towards a window. Make sure there are no metal objects nearby.
• Proper signal reception can be difficult or even impossible under the conditions listed
below.

About Auto Receive
When auto receive is turned on, the watch automatically starts to receive the time
calibration signal when the time in the Timekeeping Mode reaches 2:00 AM, 4:00 AM,
and 5:00 AM each day (calibration times).
Note
• The watch performs auto receive only if Mode Menu screen is on the display, or if
the watch is in the Timekeeping Mode, or World Time Mode when one of the
calibration times is reached. Auto receive is not performed if a calibration time is
reached while an alarm is sounding, or while you are configuring 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 Timekeeping Mode 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.
• When auto receive is turned on, the watch receives the calibration signal for two to six
minutes everyday when the Timekeeping Mode reaches each of the three calibration
times. Do not perform any button operation within six minutes before or after any of the
three calibration times. Doing so can interfere with correct calibration.
• Remember that reception of the calibration signal depends on the time kept in the
Timekeeping Mode. The receive operation is performed whenever the display shows
one of the three calibration times, regardless of whether or not the Timekeeping
Mode 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.
About the Receiving Indicator
The receiving 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.

• 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 1,000 kilometers.
• At distances further than about 500 kilometers, the
signal may become weak and reception may be
impossible under certain conditions.
• Signal reception may be poor in the shaded area on the
map, even though it is within 1,000 kilometers of the
signal transmitter.
• See the information under "Signal Receive
Troubleshooting" if you experience problems with time
calibration signal reception.
