below.

• Signal reception normally is better at night than during the day.
• Time calibration signal reception takes from one to seven minutes, but in some
cases it can take as long as 13 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
Home City code setting as shown below. If you use the watch in Japan or Europe
(each of which has two different transmitter locations), it will try to receive the time
calibration signal from one of the transmitters in your current location. If it cannot
receive the signal, it will then try to receive the time calibration signal from the other
transmitter.

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 Rugby (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.

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 one 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.
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
Weak
(Level 0)
• 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.
Transmitter Indicator
The watch has transmitter names along the bottom of the
display. The transmitter indicator flashes during signal
reception above the name of the transmitter from which
the watch is currently receiving a signal. After signal
reception is complete, the indicator will remain, without
flashing, above the name of the transmitter from which
the signal was received.
• The following shows the meaning of each of the
transmitter names along the bottom of the display.

JP40: Fukushima (Japan)
JP60: Fukuoka/Saga (Japan)
US60: Fort Collins, Colorado (the United States)

• The transmitter indicator turns off automatically at the start of the first auto receive
operation of a new day. The time of the first auto receive operation of a new day
depends on your currently selected Home City.
