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.
Battery Power Indicator and Recover Indicator
The battery power indicator on the display shows you the current status of the
rechargeable battery's power.

• 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)
Outdoor Sunlight (50,000 lux)
Sunlight Through a Window (10,000 lux)
Daylight Through a Window on a Cloudy Day (5,000 lux)
Indoor Fluorescent Lighting (500 lux)
• 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.

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
1. In the Timekeeping Mode hold down A until the city
code starts to flash, which indicates the setting screen.
2. Use D and B to select the city code you want.
• Make sure you select your Home City code before
changing any other setting.
• For full information on city codes, see the "City Code
Table".

STO, ATH, MOW,TPE, SEL, TYO, HNL, ANC, YVR, LAX, YEA, DEN, MEX, CHI,
NYC, YHZ, or YYT is selected as the Home City code. For more information, see
"Daylight Saving Time (DST)".
• The day of the week is displayed automatically in accordance with the date (year,
month, and day) settings.
12-hour and 24-hour timekeeping
• With the 12-hour format, the P (PM) indicator appears to the left of the hour digits for
times in the range of noon to 11:59 p.m. and no indicator appears to the left of the
hour digits for times in the range of midnight to 11:59 a.m.
• With the 24-hour format, times are displayed in the range of 0:00 to 23:59, without
any indicator.
• The 12-hour/24-hour timekeeping format you select in the Timekeeping Mode is
applied in all other modes.
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
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.
