• Proper signal reception can be difficult or even impossible under the conditions listed
below.
• Signal reception normally is better at night than during the day.
• Time calibration signal reception takes from four 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.

• At distances further than about 600 miles (1,000 kilometers) from the Fort Collins
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 will be impossible if the signal is blocked by mountains or other geological
formations between the watch and signal source.
Fort Collins
• This watch is designed to pick up the time calibration signal transmitted in the United
States (Fort Collins, Colorado).
Reception Range
• 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 starts to receive the time calibration signal automatically when the time in
the Timekeeping Mode reaches 0:01 a.m., 1:00 a.m., 2:00 a.m., 3:00 a.m., and 4:00
a.m. each day (calibration times). The watch also will perform an additional auto
receive at 5:00 a.m. if none of the regularly scheduled auto receive operations are
successful. 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 Time Zone, and whether standard time or Daylight
Saving Time is selected for your Home Time Zone.
Note
• The auto receive operation is performed only if the watch is in the Timekeeping
Mode when one of the calibration times is reached. It is not performed if a calibration
time is reached while you are configuring settings.
• Auto receipt of the calibration signal is 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 four to seven minutes everyday when
the time in the Timekeeping Mode reaches each of the calibration times. Do not
perform 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 is actually the correct time.
To perform manual receive
1.Place the watch on a stable surface so its 9 o’clock side
is facing towards a window.
2.In any mode, hold down B for about two seconds until
the watch beeps.
3.When you release B, the second hand will move to R
(READY) to indicate that the watch is setting up for time
calibration reception.
• The second hand will move to W (WORK) and stay there
while actual reception is in progress.
• The hour and minute hands continue to keep time
normally.
• Time calibration signal reception takes from four to
seven minutes, but in some cases it can take up to 14
minutes. Take care that you do not perform any button
operations or move the watch during this time.
• If reception is successful, the second hand will move to
Y (YES). One or two minutes later, the hands will move
to the correct time.

Note
• To interrupt a receive operation and return to the Timekeeping Mode, press any
button.
• If reception is not successful, the second hand will move to N (NO). One or two
minutes later, the second hand will resume normal operation, without any
adjustment of the hand setting.
• If the second hand is pointing to Y (YES) or N (NO), you can return to the
Timekeeping Mode by pressing any button.
Viewing the Latest Signal Reception Results
You can use the Receive Result Mode to check if signal reception was performed
correctly.

To check the latest signal reception results
Enter the Receive Result Mode.
• If the watch was able to perform a successful signal
receive operation since midnight, the second hand will
move to Y (YES). If the watch has been unable to
receive any signal successfully, the second hand will
move to N (NO).
• To return to the Timekeeping Mode, press B three
times.
• The current receive result is cleared when the first auto
receive operation is performed on the following day. This
means Y (YES) indicates successful signal reception
since the start of the current day.
• Y (YES) continues to be indicated even if an attempt at
manual receive fails after auto receive is successful.
• If you adjust the time or date setting manually, the
second hand will move to N (NO).
Signal Reception Troubleshooting
Check the following points whenever you experience problems with signal reception.
• You changed the time setting
manually.
•
The watch was not in the
Timekeeping Mode, or you performed
some button operation during the
auto receive operation.
• Signal reception results are reset at
midnight each day.
• The Home Time Zone setting is not
correct for the area where you are
using the watch.
The second
hand is
pointing at N

• Perform manual signal
receive or wait until the next
auto signal receive operation
is performed.
• Check to make sure the
watch is in a location where it
can receive the signal.
• Select the correct Home
Time Zone.

Precautions”.
Adjusting the Home Positions
If the time and date settings are wrong even after the time calibration signal is
received normally, use the following procedure to adjust their home positions.
To adjust the home positions
1.Enter the Home Position Adjustment Mode.
• If the home position of the second hand is currently
correct, it will move to the 12 o’clock position.
2.While in the Home Position Adjustment Mode, hold
down A for about five seconds. This will cause the
second hand to make one revolution and stop at its
current home position.
• The analog hands do not keep time during home
position adjustment.
3.Check the position of the second hand.
• The second hand home position is correct if it is
pointing at 12 o’clock.

home position
• If the second hand is not pointing at 12 o’clock, it
means that its home position is off. If this happens,
press B to move the second hand clockwise in one-
second steps, until it points at 12 o’clock.
4.Press A to advance to hour and minute hand home
position adjustment.
• If current hour and minute hand alignment is correct,
they will both move to 12 o’clock.
5.Check the position of the hour and minute hands.
• If the hour and minute hands are not pointing at 12
o’clock, it means that their home position is off. If this
happens, press B to move the hour and minute
hands clockwise in 10-second steps, until they point
at 12 o’clock.
• You can change the hour and minute hand movement
direction to counterclockwise by pressing A. After
that, each press of B will move the hour and minute
hands counterclockwise in 10-second steps.
