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.

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). |

1.In the Timekeeping Mode, hold down Dfor about three seconds, until
•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 Bto adjust the left dial hand position and Dto 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
•Pressing Chere will return to the setting at the beginning of step 2.
3.After everything is the way you want, press Ato 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.
• 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 Bbuttons are used to change the hand setting in various setting modes. In most cases, holding down these buttons will start

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.
Elapsed Time | Hands and Display | Operation |

60 to 70 minutes | Left dial hand: PS; Right dial | All functions enabled, except |
| hand: “12”; Other hands: | for displays |

| Stopped at 12 o’clock; | illumination, and display |
| Display: Blank | disabled. |
•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

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
•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.
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
•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.
More than 15 degrees | • Illumination may not turn on if the face of the watch is |
too high | 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. |
•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.
