Operation Guide 4365
Charging Guide
After a full charge, timekeeping remains enabled for up to about four months.
•The following table shows the amount of time the watch needs to be exposed to light each day in order to generate enough power for normal daily operations.
| Exposure Level (Brightness) | Approximate Exposure Time |
|
|
Outdoor sunlight (50,000 lux) | 6 minutes |
|
|
Sunlight through a window (10,000 lux) | 30 minutes |
|
|
Daylight through a window on a cloudy day (5,000 | 48 minutes |
lux) |
|
|
|
Indoor fluorescent lighting (500 lux) | 8 hours |
|

•Since these are the specs, we can include all the technical details.
•Watch is not exposed to light
•Internal timekeeping
•Analog hands operational 18 hours per day, sleep state 6 hours per day
•10 seconds of alarm operation per day
•1 time calibration reception per day
•Stable operation is promoted by frequent charging.

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.
Auto Return Features
•If you leave the watch in the Home Position Adjustment Mode for two or three minutes without performing any operation, it returns to the Timekeeping Mode automatically.
•If you do not perform any operation for about two or three minutes while a setting mode is selected, the watch will exit the setting mode automatically.
Scrolling
•The D and Bbutton are used to change the hand setting in various setting modes. In most cases, holding down these buttons will start
•
-One complete cycle for the hands is one revolution (360 degrees) or 24 hours.
-One complete cycle for the day is 31 days.
Radio-controlled 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, 2001 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 time within ±20 seconds a month at normal temperature.
TransmittersThis watch is designed to receive the time calibration signal transmitted from Mainflingen, Germany and the signal from Rugby, England. You can configure the watch to automatically select the transmitter that has the strongest signal.
| In this case: | The watch does this: |
The first signal auto search operation | 1. Checks the Mainflingen signal first. |

or after the city code has been changed | received, checks the Rugby signal. |
Any case other than the above. | 1. Checks the last successfully received |
| signal first. |
| 2. If the last successfully received signal |
| cannot be received, checks the other |
| signal. |
Timekeeping
•The year can be set in the range of 2001 to 2099.
•The watch’s
•The date will change automatically when the current time reaches midnight. The date change at the end of the month may take more time than normal.
•The times for the Timekeeping Mode and all the time zones of the World Time Mode are calculated in accordance with each city’s UTC differential.
•The UTC differential is a value that indicates the time difference between a reference point in Greenwich, England and the time zone where a city is located.
•The letters “UTC” is the abbreviation for “Universal Time Coordinated’, which is the
Power Saving
Power Saving enters a sleep state automatically whenever the watch is left for a certain period in an area where it is dark. The table below shows how watch functions are affected by Power Saving.
•There are actually two sleep state levels: “second hand sleep” and “function sleep”.
| Elapsed Time in Dark | Operation |
|
|
60 to 70 minutes | Second hand only is stopped, all other functions are |
(second hand sleep) | enabled. |
|
|
6 or 7 days | • All functions, including analog timekeeping, disabled |
(function sleep) | • Internal timekeeping maintained |
|
|
•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 statePerform any one of the following operations.
•Move the watch to a
•Press any button.
