Operation Guide 5033
* The areas covered by the MOW, HKG, BJS, HNL, and ANC city codes are quite
far from the time calibration signal transmitters, and so certain conditions may
cause problems with signal reception.

• 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.
Mainflingen (Germany) or Anthorn (England) transmitters: 500 kilometers (310
miles)
Fort Collins (United States) transmitter: 600 miles (1,000 kilometers)
Fukushima or Fukuoka/Saga (Japan) transmitters: 500 kilometers (310 miles)
• 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.
• The display of the watch is blank while an auto receive operation is in progress.

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 every day 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
• Use the receiving indicator as a guide for checking signal strength and for finding the
best location for the watch during signal receive operations.
• 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.

World Time
The World Time Mode digitally displays the current time in
48 cities (29 time zones) around the world.
• If the current time shown for a city is wrong, check your
Home City time settings and make the necessary
changes.
• The watch will perform a signal reception even if it is in
