Use the procedure under “To conﬁ gure Home City settings” (page E-26) to conﬁ gure your Home City and daylight saving time settings.

Important!

Proper World Time Mode data depends on correct Home City, time, and date settings in the Timekeeping Mode. Make sure you configure these settings correctly.

3. Set the current time.

Warning! Leaving the watch in bright light for charging 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.

Power Levels

You can get an idea of the watch’s power level by observing the battery power indicator in the lower digital dial.

Battery power indicator

Charging the Watch

The face of the watch is a solar panel that generates power from light. The generated power charges a built-in rechargeable battery, which powers watch operations. The watch charges whenever it is exposed to light.

Charging Guide

Important!

Allowing the watch to become very hot can cause the digital displays to black out. The appearance of the LCD should become normal again when the watch returns to a lower temperature. Turn on the watch’s Power Saving function (page E-19) and keep it in an area

normally exposed to bright light when storing it for long periods. This helps to ensure that power does not run down. Storing the watch for long periods in an area where there is no light or wearing it in

such a way that it is blocked from exposure to light can cause power to run down. Expose the watch to bright light whenever possible.

Level

(L and

LOW)

(CHG)

The ﬂ ashing x LOW message at Level 3 (L) tells you that battery power is very low, and that exposure to bright light for charging is required as soon as possible.

Whenever you are not wearing the watch, leave it in a location where it is exposed to light.

Best charging

performance is achieved by exposing the watch to the strongest light available.

All functions and display indicators disabled except for timekeeping and display of CHG (charge) in the lower digital dial. Hour and minute hands stopped at 12 o’clock.

When wearing the watch, make sure that its face is not blocked from light by the sleeve of your clothing.

The watch may enter a

sleep state (page E-19) if its face is blocked by your sleeve even only partially.

At Level 5, all functions are disabled and settings return to their initial factory x defaults. Once the battery reaches Level 2 (M) after falling to Level 5, reconﬁ gure the current time, date, and other settings. Display indicators reappear as soon as the battery is charged from Level 5 to

Level 2 (M). Leaving the watch exposed to direct sunlight or some other very strong light x 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. 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.

Power Recovery Mode

Performing multiple illumination, beeper, and/or high-speed hand movement x operation during a short period may cause all of the battery power indicators (H, M, and L) to start ﬂ ashing in the lower digital dial. This indicates that the watch is in the power recovery mode. Illumination, alarm, countdown timer alarm, and hourly time signal operations will be disabled until battery power recovers. Battery power will recover in about 15 minutes. At this time, the battery power

indicators (H, M, L) will stop ﬂ ashing. This indicates that the functions listed above are enabled again. If all of the battery power indicators (

x H, M, L) are ﬂ ashing and the CHG (charge)

message also is ﬂ ashing, it means the battery level is very low. Expose the watch to bright light as soon as possible. Frequent ﬂ ashing of all of the battery power indicators (

x H, M, L) probably means

that remaining battery power is low. Leave the watch in bright light to allow it to charge.

For details about the operating time and daily operating conditions, see the “Power x Supply” (page E-70) section of the Speciﬁ cations.

Power Saving

When turned on, 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.

For information about enabling and disabling power saving, see “To turn Power

Saving on and off” (page E-65).

There actually are two sleep state levels: “display sleep” and “function sleep”.

Elapsed Time in Dark Digital Dials Operation

60 to 70 minutes (display sleep) Blank

6 or 7 days (function sleep) Blank

Digital dials are off, but all functions are enabled.

Hour and minute hands stop at 12 o’clock. All functions are disabled, but timekeeping is maintained.

Operation Guide 5231

The watch will not enter a sleep state between 6:00 AM and 9:59 PM. If the watch x is already in a sleep state when 6:00 AM arrives, however, it will remain in the sleep state.

The watch will not enter a sleep state while it is in the Stopwatch Mode or Countdown Timer Mode.

To recover from the sleep state

Move the watch to a well-lit area or press any button.

General Functions (All Modes)

The functions and operations described in this section can be used in all of the modes.

Auto Return Features

The watch returns to the Timekeeping Mode automatically if you do not perform any button operation for two or three minutes in the Alarm Mode.

If you leave the watch in a setting mode (with ﬂ ashing digits) for two or three minutes without performing any operation, the watch will exit the setting mode automatically.

Initial Screens

When you enter the World Time or Alarm Mode, the data you were viewing when you last exited the mode appears ﬁ rst.

Scrolling

The B and D buttons are used in the setting mode to scroll through data. In most cases, holding down these buttons during a scroll operation scrolls through the data at high speed.

Conﬁ guring Home City Settings

There are two Home City settings: actually selecting the Home City, and selecting either standard time or daylight saving time (DST).

City code

For details about city codes, see the “City Code Table” at the back of this

manual. Whenever you enter a setting mode, the analog hands will automatically move to x positions that allow easier viewing of the digital dials.

E-26

After the setting is the way you want, press 5. A to return to the Timekeeping Mode.

The

x DST indicator appears to indicate that Daylight Saving Time is turned on.

Exiting a setting mode will normally cause the hands to return to regular

timekeeping automatically. However, if you manually move the hands (page E-61) and then enter a setting mode, they will not return to regular timekeeping automatically when you exit the setting mode. In this case, you will need to return the hands to their normal positions manually (page E-62).

Note

After you specify a city code, the watch will use UTC* offsets in the World Time x Mode to calculate the current time for other time zones based on the current time in your Home City.

Coordinated Universal Time, the world-wide scientiﬁ c standard of timekeeping.

The reference point for UTC is Greenwich, England.

E-28

To conﬁ gure Home City settings

In the Timekeeping Mode, hold down 1. A for about two seconds until ADJ appears in the right digital dial. When you release A, the city code and city name will scroll across the right digital dial. This is the setting mode.

The watch will exit the setting mode automatically if

you do not perform any operation for about two or three minutes.

DST indicator

To change the Daylight Saving Time (summer time) setting

DST indicator

Use 2. D (East) and B (West) to scroll through the city codes in the right digital dial until the one you want to use as your Home City is displayed.

Press 3. C so the DST indicator is ﬂ ashing in the left digital dial, which indicates the DST setting mode.

Press 4. D to toggle the DST setting between Daylight Saving Time (ON) and Standard Time (OFF) in the right digital dial.

Note that you cannot switch between standard time and daylight saving time (DST) while UTC is selected as your Home City.

Whenever you enter a setting mode, the analog hands

will automatically move to positions that allow easier viewing of the digital dials. This is the setting mode.

Press 2. C to enter the DST setting mode. Press 3. D to toggle the DST setting between Daylight

Saving Time (ON) and Standard Time (OFF).
