•
Time calibration signal reception takes from two to six minutes. Take care that you
do not perform any button operations or move the watch during this time.
•
Under good reception conditions, signal reception is possible within a radius of
about 2,000 miles (3,000 kilometers) from the Fort Collins transmitter.
•
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.
•
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.
and 2:00 a.m. (calibration times).
If both the 1 o’clock and 2 o’clock signal receptions are not successful, the watch will
try to receive the signal again at the top of each hour up until 5:00 a.m. or until one
more reception is successful.
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 if a setting
screen (a screen with a flashing setting) is on the display.
•
Auto receipt 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
six minutes everyday when the Timekeeping Mode time reaches each of the
calibration times. Do not perform any button operation within six 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.
Receiving indicator
Weak
(Level 1)
Strong
(Level 4)
•
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 4 receiving indicator will remain on the display in all modes. The
Level 4 receiving indicator will not be displayed if signal reception was unsuccessful
or after you adjust the current time setting manually.
•
The Level 4 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 4 receiving indicator indicates that at least one of the auto calibration
signal receive operations was successful. Note, however, that the Level 4 receiving
indicator is cleared from the display at 1:00 a.m. each day.
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
D
for about two
seconds until the watch beeps.
•
Release
D
and the message
RC!
appears to indicate
that signal reception has started.
•
Time calibration signal reception takes from two to six
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.

Signal Receive Troubleshooting
Check the following points whenever you experience problems with calibration signal
reception.
Problem
Cannot perform
manual receive.
Auto receive is
turned on, but
the Level 4
receiving
indicator does
not appear on
the display.
Probable Cause
•
The watch is not in the Timekeeping Mode.
•
Your current Home City is not one of the
following city codes:
LAX
,
DEN
,
CHI
, or
NYC
.
•
You changed the time setting manually.
•
The watch was not in the Timekeeping
or World Time Mode, or you performed
some button operation during the auto
receive operation.
What you should do
•
Enter the Timekeeping Mode
and try again.
•
Select
LAX
,
DEN
,
CHI
, or
NYC
as your Home City.
•
Perform manual signal receive
or wait until the next auto
signal receive operation is
performed.
Auto receive is

the Level 4
receiving
indicator does
not appear on
the display.
Time setting is
incorrect
following signal
reception.
•
Even if receive is successful, the Level 4
receiving indicator disappears every day
at 1 am.
•
Time data (hour, minutes, seconds) only
was received during the last receive
operation. The Level 4 receiving
indicator appears only when time data
and date data (year, month, day) are
both received.
•
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.
•
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.
•
Change the DST setting to
Auto DST.
•
Select the correct Home City
code.
•
