Operation Guide 3184
•Never try to remove or replace the watch’s rechargeable battery yourself. Use of the wrong type of battery can damage the watch.
•All data stored in memory is deleted, and the current time and all other settings return to their initial factory defaults whenever battery power drops to Level 5 and when you have the battery replaced.
•Turn on the watch’s Power Saving function and keep it in an area normally exposed to bright light when storing it for long periods. This helps to keep the rechargeable battery from going dead.

Read This Before You Set the Time and Date!
This watch is preset with a number of city codes, each of which represents the time zone where that city is located. When setting the time, it is important that you first select the correct city code for your Home City (the city where you normally use the watch). If your location is not included in the preset city codes, select the preset city code that is in the same time zone as your location.
•Note that all of the times for the World Time Mode city codes are displayed in accordance with the time and date settings you configure in the Timekeeping Mode.
To set the time and date manually
•At Level 5, all functions are disabled and settings return to their initial factory defaults. Once the battery reaches Level 2 after falling to Level 5, reconfigure the current time, date, and other settings.
•The watch’s Home City code setting will change automatically to TYO (Tokyo) whenever the battery drops to Level 5. With this Home City code setting, the watch is configured to receive the time calibration signals of Japan. If you are using the watch in North America, Europe, or China, you will need to change the Home City code setting to match your location whenever the battery drops to Level 5.
•Display indicators reappear as soon as the battery is charged from Level 5 to Level 2.
•Leaving the watch exposed to direct sunlight or some other very strong light source can cause the battery power indicator to show a reading temporarily that is higher than the actual battery level. The correct battery level should be indicated after a few minutes.
•If you use the light or alarms a number of times during a
short period, all segments of the battery power indicator flash and the following operations become temporarily disabled as battery power recovers.
- Display illumination
- Alarm and hourly time signal - Access to Diving Mode
- Time calibration signal reception
After some time, the battery power indicator should stop flashing to indicate that battery power is back to normal. At this time the watch should return to normal operation.
•If the battery power indicator frequently flashes, it means that battery power is low. Leave the watch in bright light to allow it to charge.
Charging Precautions
Certain charging conditions can cause the watch to become very hot. Avoid leaving the watch in the areas described below whenever charging its rechargeable battery. Also note that allowing the watch to become very hot can cause its liquid crystal display to black out. The appearance of the LCD should become normal again when the watch returns to a lower temperature.
Warning!
Leaving the watch in bright light to charge its rechargeable battery can cause it to become quite hot. Take care when handling the watch to avoid burn injury. The watch can become particularly hot when exposed to the following conditions for long periods.
•On the dashboard of a car parked in direct sunlight
•Too close to an incandescent lamp
•Under direct sunlight
Charging Guide
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) | 5 minutes |
Sunlight Through a Window (10,000 lux) | 24 minutes |
Daylight Through a Window on a Cloudy Day (5,000 lux) | 48 minutes |
Indoor Fluorescent Lighting (500 lux) | 8 hours |
•For details about the battery operating time and daily operating conditions, see the “Power Supply” section of the Specifications.
•Stable operation is promoted by frequent exposure to light.
Recovery Times
The table below shows the amount exposure that is required to take the battery from one level to the next.

Daylight Saving Time (DST)
Daylight Saving Time (summer time) advances the time setting by one hour from Standard Time. Remember that not all countries or even local areas use Daylight Saving Time.
The time calibration signals transmitted from Mainflingen (Germany), Anthorn (England), or Fort Collins (the United States) include both Standard Time and DST data. When the Auto DST setting is turned on, the watch switches between Standard Time and DST (summer time) automatically in accordance with the signals.
•Though the time calibration signals transmitted by the Fukushima and Fukuoka/ Saga, Japan transmitters include summer time data, summer time currently is not implemented in Japan (as of 2008).
•The default DST setting is Auto DST (AvtA) whenever you select LIS, LON, MAD, PAR, ROM, BER, STO, ATH, MOW, TYO, ANC, YVR, LAX,YEA, DEN, MEX, CHI, NYC, YHZ, or YYT as your Home City code.
•If you experience problems receiving the time calibration signal in your area, it probably is best to switch between Standard Time and Daylight Saving Time
(summer time) manually.
