Operation Guide 5135
•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
•Press any button.
Radio-controlled Atomic Timekeeping Precautions
•Strong electrostatic charge can result in the wrong time being set.
•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, and auto receive settings.
•The Home City setting reverts to the initial default of TYO (Tokyo) whenever the battery power level drops to Level 5 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.

Approximate battery operating time: 4 months (from full charge to Level 4) under the following conditions:
•Watch not exposed to light
•Internal timekeeping
•Display on 18 hours per day, sleep state 6 hours per day
•1 illumination operation(1.5 second) per day
•10 seconds of alarm operation per day
•Approximately 4 minutes of signal reception per day
City Code Table
•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 signal 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 signals transmitted from China (Shangqiu City).
•When your Home City is LON, PAR, ATH (which can receive both the Anthorn and Mainflingen signals), the watch first tries to pick up the signal it last successfully received. 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 LON, Mainflingen for PAR and ATH).
•When your Home City is TYO (which can receive both 40 kHz and 60 kHz signals), the watch first tries to pick up the signal it last successfully received. If that fails, it tries the other signal.

Scrolling
The C button is used in various modes and setting screens to scroll through data on the display. In most cases, holding down this button during a scroll operation scrolls at high speed.
Initial Screens
When you enter the World Time Mode or Alarm Mode, the data you were viewing when you last exited the mode appears 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.
World Time
•The seconds count of the World Time is synchronized with the seconds count of the Timekeeping Mode.
Illumination Precautions
An LED
•The illumination provided by the light may be difficult to see when viewed under direct sunlight.
•Illumination turns off automatically whenever an alarm sounds.
•Frequent use of illumination shortens the battery operating time.
•Based on data as of December 2009.
•The rules governing global times (UTC offset and GMT differential) and summer time are determined by each individual country.
