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.
• The watch will receive the time calibration signal automatically from the applicable
transmitter (in the middle of the night) and update its settings accordingly. For
information about the relationship between city codes and transmitters, see “Home
City Codes and Transmitters”.
• Under factory default settings, auto receive is turned off for all of the following city
codes: HNL (Honolulu), ANC (Anchorage), ATH (Athens), and MOW (Moscow). For
details about turning on auto receive for these city codes, see “To turn auto receive
on and off”.
• You can disable time signal reception, if you want. See “To turn auto receive on and
off” for more information.
• See the maps under “Reception Ranges” for information about the reception ranges
of the watch.
• If you are in an area that does not use Daylight Saving Time (summertime), 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”.
This watch receives a time calibration signal and updates
its time setting accordingly.
• Supported time calibration signals: United States (Fort
Collins), England (Rugby).
Current Time Setting
This watch adjusts its time setting automatically 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 specify your Home City (the city where you
normally will use the watch). For more information, see
“To specify your Home City”.
1. In the Timekeeping Mode, hold down A until the city
code starts to flash, which indicates the setting screen.
2. Press D(east) and B(west) to select the city code you
want to use as your Home City.
• Time calibration signal reception is supported when
any one of the city codes shown in the table below is
selected as your Home City.

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.

• Make sure the watch is facing the right way.
• Proper signal reception can be difficult or even impossible under the conditions listed
below.
Inside or

buildings
• Signal reception normally is better at night than during the day.
• Time calibration signal reception takes from two to seven minutes, but in some
cases it can take as long as 14 minutes. Take care that you do not perform any
button operations or move the watch during this time.
• The time calibration signal the watch will attempt to pick up depends on its current

• Signal reception may not be possible at the distances noted below during certain
times of the year or day. Radio interference may also cause problems with reception.
Rugby (England) transmitter: 500 kilometers (310 miles)
Fort Collins (United States) transmitter: 600 miles (1,000 kilometers)
• 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
• When a calibration time is reached, the watch will receive the calibration signal only
if it is in either the Timekeeping Mode or World Time Mode. Reception is not
performed if a calibration time is reached while you are configuring settings.
• 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.
• The watch receives the calibration signal for two to seven minutes everyday when
the time in the Timekeeping Mode reaches each of the calibration times. Avoid
performing any button operation within seven 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 current time 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 displayed
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.
Receiving indicator
• 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.
