• Signal reception is normally better at night than during the day.
• Time calibration signal reception takes from two to five minutes. Take care that you
do not perform any button operations or move the watch during this time.
• This watch is designed to pick up the time calibration signal transmitted from Fort
Collins, Colorado (USA).
Reception Range
• At distances further than about 600 miles (1,000 kilometers) from the transmitter,
signal reception may not be possible during certain times of year or times of day.
Radio interferance may also cause problems with reception.

• Even when the watch is within the reception range of the transmitter, signal
reception is 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 Receive Troubleshooting” if you experience
problems with time calibration signal reception.
About Auto Receive
When auto receive is turned on, the watch starts to receive the time calibration signal
automatically when the time in the Timekeeping Mode reaches midnight, 1:00 a.m. ,
2:00 a.m., 3:00 a.m., 4:00 a.m., and 5:00 a.m. (calibration times).
When any auto receive is successful, the remaining auto receive operations are not
performed.
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 is actually the correct time.
• If more than one auto receive is successful, the watch uses the data from the last
successful receive to adjust settings. 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.
Weak
(Level 0)
Strong
(Level 3)
• 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.

To perform manual receive
1.Place the watch on a stable surface so its top (12
o’clock side) is facing towards a window.
2.In the Timekeeping Mode, hold down C for about two
seconds until RC! appears on the display.
• Time calibration signal reception takes from two to five
minutes. Take care that you do not perform any button
operations or move the watch during this time.
• After signal reception is complete, the display of the
watch changes to the Last Signal screen.
Note
• To interrupt a receive operation and return to the
Timekeeping Mode, press C.
• If the receive operation is unsuccessful, the message
ERR appears on the display for about one or two
minutes. After that, the watch returns to the Timekeeping
Mode.
• You can also change from the Last Signal or
ERR screen
to the normal timekeeping screen by pressing C.

Signal Receive Troubleshooting
Check the following points whenever you experience problems with calibration signal
reception.
• For further information, see “Important!” under “Time Calibration Signal Reception”
and “Radio-controlled Atomic Timekeeping Precautions”.
Problem
Cannot perform
manual receive.
Time setting is
incorrect
following signal
reception.
Probable Cause
• The watch is not in the Timekeeping
Mode.
• Your current Home City is not one of the
following city codes:
YVR, LAX, YEA, DEN, MEX, YWG,
CHI, MIA, YTO, NYC, YHZ, or YYT.
• If the time is one hour off, the DST
setting may be incorrect.
• The Home City code setting is not
correct for the area where you are using
the watch.
What you should do
• Enter the Timekeeping Mode
and try again.
• Select YVR, LAX, YEA, DEN,
MEX, YWG, CHI, MIA, YTO,
NYC, YHZ, or YYT as your
Home City.
• Change the DST setting to
Auto DST.
• Select the correct Home City
code.
World Time
The World Time Mode shows you 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.
• All of the operations in this section are performed in the
World Time Mode, which you enter by pressing B.
To view the time in another city
While in the World Time Mode, press C to scroll eastward through the city codes
(time zones).
• For full information on city codes, see “City Code Table”.
