Hand Home Position Correction
The hands of the watch can be thrown off by exposure to strong magnetism or impact.
If that happens, check if the home positions of the hands are correct and adjust the
home positions as required.
To adjust the home positions
1.In the Timekeeping Mode, hold down D for about three
seconds, until H-SET appears on the upper display.
• The dial hands are in their correct home positions
when the left dial hand moves to C (CHG) and the
right dial hand moves to 12. If they don’t, use B to
adjust the left dial hand position and D to adjust the
right dial hand position.
2.After confirming that both dial hands are in their correct
home positions, press C.
• This will change to hour hand and minute hand home
position manual correction.

• The hour and minute hands are in their correct home
positions if they are at 12 o’clock. If they are not, use
D (+) and B (–) to adjust their positions as required.
• Pressing C here will return to the setting at the
beginning of step 2.
3.After everything is the way you want, press A to return
to the Timekeeping Mode.
• After you complete the home position adjustment
procedure, place the watch in a location that allows
good time calibration signal reception, and then perform
a manual receive operation. See “To perform manual
receive” for more information.

Reference
This section contains more detailed and technical information about watch operation.
It also contains important precautions and notes about the various features and
functions of this watch.
Power Saving Function
When turned on, the Power Saving function enters a sleep
state automatically whenever the watch is left in an area
for a certain period where it is dark. The table below
shows how watch functions are affected by the Power
Saving function.
• Wearing the watch inside the sleeve of clothing can cause it to enter the sleep state.
• The watch will not enter the sleep state between 6:00 AM and 9:59 PM. If the watch
is already in the sleep state when 6:00 AM arrives, however, it will remain in the
sleep state.
To recover from the sleep state
Perform any one of the following operations.
• Move the watch to a well-lit area.
• Press any button.
• Angle the watch towards your face for reading.

To turn Power Saving on and off
1.In the Timekeeping Mode, hold down A for about five
seconds until the left dial hand points to T1 and the city
code flashes on the upper display. This is the setting
mode.
2.Press C nine times until PS appears in the upper
display and a flashing
or appears in the lower

On/Off status
Radio-controlled Atomic Timekeeping Precautions
• Strong electrostatic charge can cause the time setting to be thrown off.
• The time calibration signal bounces off the ionosphere. Because of this, such factors
as changes in the reflectivity of the ionosphere, as well as movement of the
ionosphere to higher altitudes due to seasonal atmospheric changes or the time of
day may change the reception range of the signal and make reception temporarily
impossible.
• Even if the time calibration signal is received properly, certain conditions can cause
the time setting to be off by up to one second.
• The current time setting in accordance with the time calibration signal takes priority
over any time settings you make manually.
• The watch is designed to update the date and day of the week automatically for the
period January 1, 2000 to December 31, 2099. Setting of the date by the time
calibration signal cannot be performed starting from January 1, 2100.
• This watch can receive signals that differentiate between leap years and non-leap
years.
• Though this watch is designed to receive both time data (hour, minutes, seconds)
and date data (year, month, day), certain signal conditions can limit reception to time
data only.
• If you are in an area where proper time calibration signal reception is impossible, the
watch keeps the time with the precision noted in “Specifications”.
• If you have problems with proper time calibration signal reception or if the time
setting is wrong after signal reception, check your current city code, and DST
(summer time) settings.
• The Home City setting reverts to the initial default of
TYO (Tokyo) whenever the
battery power drops to Level 5 (CHG) or when you have the rechargeable battery
replaced. If this happens, change the Home City to the setting you want.
Transmitters
The time calibration signal received by this watch depends on the currently
selected Home City code.
• When a U.S. time zone is selected, the watch receives the time calibration signal
transmitted from the United States (Fort Collins).
• When a Japanese time zone is selected, the watch receives the time calibration
signals transmitted from Japan (Fukushima and Fukuoka/Saga).
• When a European time zone is selected, the watch receives the time calibration
signals transmitted from Germany (Mainflingen) and England (Anthorn).
• When a China time zone is selected, the watch receives the time calibration signal
transmitted from China (Shangqiu City).
• When your Home City is LIS, LON, MAD, PAR, ROM, BER, STO, ATH, MOW (which
can receive both the Anthorn and Mainflingen signals), the watch first tries to pick up
the signal it last received successfully. If that fails, it tries the other signal. For the first
receive after you select your Home City, the watch tries the nearest signal first
(Anthorn for LIS, LON, Mainflingen for MAD, PAR , ROM, BER, STO, ATH, and MOW).
Auto Return Features
• If you leave the watch with a flashing setting on the display for two or three minutes
without performing any operation, the watch will exit the setting mode automatically.
• The watch will return to the Timekeeping Mode automatically if you do not perform
any operation for two or three minutes in the Alarm Mode.
High-Speed Movement
• The D and B buttons are used to change the hand setting in various setting
modes. In most cases, holding down these buttons will start high-speed movement
of the applicable hand(s).
Initial Screens
When you enter the World Time Mode or Alarm Mode, the data you were viewing
when you last exited the mode will appear first.
Timekeeping
• Resetting the seconds to
00
while the current count is in the range of 30 to 59
causes the minutes to be increased by 1. In the range of 00 to 29, the seconds are
reset to
00
without changing the minutes.
• The year can be set in the range of 2000 to 2099.
• The watch’s built-in full automatic calendar makes allowances for different month
lengths and leap years. Once you set the date, there should be no reason to change
it except when battery power drops to Level 5 (CHG).
• The current time for all city codes in the Timekeeping Mode and World Time Mode is
calculated in accordance with the Coordinated Universal Time (UTC) for each city,
based on your Home City time setting.
Illumination Precautions
• Illumination may be hard to see when viewed under direct sunlight.
• Illumination turns off automatically whenever an alarm sounds.
• Frequent use of illumination runs down the battery.
Auto light switch precautions
• The auto light switch is turned off automatically whenever battery power is at Level 4
(CHG).
• Avoid wearing the watch on the inside of your wrist. Doing so causes the auto light
switch to operate when it is not needed, which shortens battery life. If you want to
wear the watch on the inside of your wrist, turn off the auto light switch feature.
• Illumination may not turn on if the face of the watch is
more than 15 degrees above or below parallel. Make
sure that the back of your hand is parallel to the ground.
• Illumination turns off in about one second, even if you
keep the watch pointed towards your face.
More than 15 degrees
too high
• Static electricity or magnetic force can interfere with proper operation of the auto
light switch. If illumination does not turn on, try moving the watch back to the starting
position (parallel with the ground) and then tilt it back toward you again. If this does
not work, drop your arm all the way down so it hangs at your side, and then bring it
back up again.
• Under certain conditions, illumination may not turn on until about one second after
you turn the face of the watch towards you. This does not necessarily indicate
malfunction of the auto light switch.
• You may notice a very faint clicking sound coming from the watch when it is shaken
back and forth. This sound is caused by mechanical operation of the auto light
switch, and does not indicate a problem with the watch.
