This watch receives a time calibration signal and updates
its time setting accordingly. The time calibration signal
includes both Standard Time and Daylight Saving Time
(summer time) data.
• This watch is designed to pick up the time calibration
signal transmitted from Mainflingen, Germany and the
signal from Rugby, England.
• In the Timekeeping Mode, you can press A to toggle
the display contents.
Current Time Setting
This watch adjusts its time setting automatically in
Seconds
accordance with a time calibration signal. You can also
perform a manual procedure to set the time and date,
when necessary.
1. In the Timekeeping Mode, hold down A until the city
code starts to flash, which indicates the setting screen.
2. Use D(east) and B(west) to select the city code you
l
l
want to use as your Home City.
• The following are the city codes for major cities in the
Western Europe time zones.
World Time Mode
▲
Alarm Mode
▲
Countdown Timer ModeStopwatch Mode

Important!
• Normally, your watch should show the correct time as soon as you select your Home
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 or you
can set the time manually.
• If you are in an area that does not use Daylight Saving Time (summer time), turn off
the DST 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 receives the time calibration signal automatically up to
six times a day. When any auto receive is successful, the remaining auto receive
operations are not performed. 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!
• When getting ready to receive the time calibration signal, 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.

Operation Guide 3017
• Signal reception is normally better at night than during the day.
• Time calibration signal reception takes from two to six minutes, but some cases it
can take as long as 12 minutes. Take care that you do not perform any button
operations or move the watch during this time.
• When within range of the applicable transmitter, this watch can receive either the
Germany (Mainflingen) or England (Rugby) time calibration signals.
See “Transmitters” for more information.
Reception Ranges
1,500 kilometers
Rugby
500 kilometers
• This watch is designed to receive the time calibration signal transmitted from
Mainflingen, Germany and the signal from Rugby, England. Signal reception is
possible within the area represented by a circle with a radius of about 1,500
kilometers.
• At distances further than about 500 kilometers from a transmitter, signal reception
may not be possible during certain times of year or times of day. Radio interference
may also cause problems with reception.
• Even when the watch is within the reception range of the transmitter, signal
reception will be 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.
• See the information under “Signal Reception Troubleshooting” if you experience
problems with time calibration signal reception.
About Auto Receive
The watch receives the time calibration signal automatically up to six times a day.
When any auto receive is successful, the remaining auto receive operations are not
performed. The reception schedule (calibration times) depends on your currently
selected Home City, and whether standard time or Daylight Saving Time is selected
for your Home City.
Note
• Auto receive is turned on whenever LIS, LON, BCN, MAD, PAR, MIL, ROM, BER,
STO, or ATH is selected as the Home City code.

Note
• Auto receive works only while the watch is in the Timekeeping Mode or World Time
Mode. Auto receive is not performed if an auto receive time is reached while an
alarm is sounding, while a countdown timer operation is in progress, or while a
setting screen (a screen with a flashing setting) is on the display.
• Auto receive 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 receive the signal easily.
• When auto receive is turned on, the watch receives the calibration signal for two to
five minutes everyday when the Timekeeping Mode time reaches each of the
calibration times. Do not perform any button operation within five minutes before or
after any one of the 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 will be performed whenever the display
shows any one of the calibration times, regardless of whether or not the
Timekeeping Mode time actually is the correct time.
• Calibration signal reception is disabled while a countdown timer operation is in
progress.
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.
• Even in an area where signal strength is strong, it takes about 10 seconds for signal
reception to stabilize enough for the receiving indicator to indicate signal strength.
• Use the receiving indicator as a guide for checking signal strength and for finding the
best location for the watch during signal receive operations.
• Following reception of the time calibration signal and calibration of the watch’s time
setting, the Level 3 receiving indicator will remain on the display in all modes. The
Level 3 receiving indicator will not be displayed if signal reception was unsuccessful
or after you adjust the current time setting manually.
• The Level 3 receiving indicator is displayed only when the watch is able to receive
both time and date data successfully. It does not appear when only time data is
received.
• The Level 3 receiving indicator indicates that at least one of the auto calibration
signal receive operations was successful. Note, however, that the Level 3 receiving
indicator is cleared from the display when the first auto receive operation of the day
is performed.
