What you should do next depends on whether you are using Auto Receive or Manual Receive.2.
Auto Receive: Leave the watch over night in the location you selected in step 2. See “Auto Receive” for •
details.
Manual Receive: Perform the operation under “To perform manual receive”. •
Auto Receive
With Auto Receive, the watch performs the receive operation each day automatically up to three times •
between the hours of 2 a.m. and 4 a.m. (1 a.m. and 3 a.m. for the Chinese calibration signal). When any
receive operation is successful, none of the other receive operations for that day are performed.
When a calibration time is reached, the watch will perform the receive operation only if it is in the regular •
timekeeping. The receive operation is not performed if a calibration time is reached while you are
configuring settings.
To perform manual receive
In the regular timekeeping, keep 1. A depressed (for about two seconds) as the
x Second Hand goes
through the following sequence.
Moves to • YES (Y) or NO (N) to indicate the last signal reception result, then to Receiving (RC).
The 2.
x Second Hand indicates the operations the watch is currently performing.
When the x Second Hand is
pointed here:
It means this:
Receiving (RC) Reception is in progress.
YES (Y) Reception was completed successfully.
NO (N) Reception failed for some reason.
The receive operation is complete when the 3. x Second Hand moves to YES (Y)
or NO (N) for about five seconds, and then resumes regular timekeeping.
You can return to the regular timekeeping manually by pressing • A while the
x Second Hand is pointing to YES (Y) or NO (N).
When the receive operation is successful, the watch adjusts the time setting •
accordingly. It does not adjust the setting if the operation failed.
Note
To interrupt a receive operation and return to the regular timekeeping, press •
any button.
To check the result of the latest receive operation
In the regular timekeeping, press A.
The •
x Second Hand will move to YES (Y) for five seconds if the latest receive
operation was successful, or NO (N) if it was not. After that, regular timekeeping
will resume.
You can return to the regular timekeeping manually by pressing • A while the
x Second Hand is pointing to YES (Y) or NO (N).
Note
The •
x Second Hand will indicate NO (N) if you have adjusted the time setting
manually since the latest receive operation.
Radio-controlled Atomic Timekeeping Precautions
Strong electrostatic charge can result in the wrong time setting. •
Even if a receive operation is successful, certain conditions can cause the time setting to be off by up to •
one second.
If you are in an area where signal reception is not possible, the watch keeps time with the precision noted •
in “Specifications”.
The receive operation is disabled under any of the following conditions. •
While power is at Level 2 or lower −
When the watch is in the function sleep state (“Power Saving”) −

Specifying Your Current Location and Setting the Time
Use the procedure in this section to specify the location where you will be using the watch. You also can adjust
the time when the watch is unable to receive a time calibration signal.
In the regular timekeeping, keep 1. A depressed (for about five seconds) as
the
x Second Hand and b Stopwatch Second Hand go through the sequence
described below.
x • Second Hand: Last signal reception result → RC → Current location setting
b • Stopwatch Second Hand: 30 (Indicates the setting mode.)
Press 2. C to select the location you want.
Each press of • C cycles through the three settings shown below.
City Name Location
TOKYO (TYO) Japan
HONG KONG (HKG) China
OFF Receive off*
Select * OFF for the location setting whenever using the watch in any other
geographic area other than Japan or China. When OFF is selected, the watch
does not receive any time calibration signal, so you will need to adjust the time
setting manually as required.
Press 3. A. What you should do next depends on the location setting you selected
in step 2.
If you selected • OFF, the
x Second Hand and b Stopwatch Second Hand
will move to 12 o’clock, which indicates the hour and minute setting mode.
Proceed to step 4, below.
If you selected • TOKYO (TYO) or HONG KONG (HKG) for the location setting,
pressing A will return to regular timekeeping. The hands of the watch will
move to the current time in the location you selected, which completes this
setting procedure.
Use the 4. C (+1 minute) and B (–1 minute) buttons to change the current time
setting.
Holding down either button for about two seconds and then releasing it starts •
high-speed hand movement in the applicable direction.
Pressing • C and B at the same time will start high-speed hand movement,
which will continue until the hands complete a 24-hour rotation.
To stop high-speed hand movement, press any button. •
Check the •
v 24-hour Hand to make sure that the time is set properly
(1:00 a.m. = 1 o’clock, 1:00 p.m. = 13 o’clock).
After the setting is the way you want, press 5. A.
This will exit the setting mode and the •
x Second Hand will resume regular
timekeeping.
For best timekeeping accuracy, press • A on a time signal from the TV or radio.
The watch will exit the setting mode automatically if you do not perform any •
button operation for about two or three minutes.

Note
The Stopwatch Mode can indicate elapsed time up to 20 minutes, 00 seconds. •
Resetting the stopwatch will cause the •
n Stopwatch Minute Hand and b Stopwatch Second Hand to rotate
counterclockwise until they reach their 12 o’clock positions. In some cases, the stopwatch second hand will
move counterclockwise to 12 o’clock and then make one full rotation clockwise before stopping.
Hand Home Position Adjustment
If the time setting of your watch is not correct even though time calibration signal reception is being performed
normally, use the procedure in this section to check the home positions of the hands and make adjustments
as required.
Note that you do not need to perform the following operation if your watch is showing the correct time.
Important!
When performing the following procedure, it is recommended that after you move to a home position, you •
press the B button to move the setting back one step. Next, press the C button to return it to the home
position. This helps to ensure better home position adjustment accuracy.
In the regular timekeeping, hold down 1. A for about 10 seconds until the
c Minute Hand and x Second Hand move to 12 o’clock.
The • x Second Hand goes through the sequence described below.
Last signal reception result → RC → Current location setting → Keep A
depressed until the
x Second Hand starts to move counterclockwise. You can
release A at this time.
The •
c Minute Hand and x Second Hand are in their correct home positions if
they are pointed precisely at 12 o’clock. If the hands are in the correct home
positions, advance to step 4.
