Timekeeping

Use the Timekeeping Mode to set and view the current time and date.

Read This Before You Set the Time and Date !
The times displayed in the Timekeeping Mode and World Time Mode are linked. Because of this, make sure you select a city code for your Home City (the city where you normally use the watch) before you set the time and date.

• For full information on city codes, see the “City Code Table” at the back of this manual.

To set the time and date

   • See “Daylight Saving Time (DST)” on page EN-14 for details about the DST setting.
4. Press A to exit the setting screen.

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.

To toggle the Timekeeping Mode time between DST and Standard Time

• The P indicator is not displayed with the Timekeeping Mode time on the Preset Timer Mode, Countdown Timer Mode, World Time Mode, and Alarm Mode screens.

Stopwatch

The stopwatch lets you measure elapsed time. The upper display and lower display can be used for official timing of an event or game.

• The measurement range of the upper display is 59 minutes 59 seconds.
• The measurement range of the lower display is 99 minutes 59 seconds.
• The stopwatch continues to run, restarting from zero after it reaches its limit, until you stop it.

If the event is interrupted for some reason, you can press D to pause and resume timing in the upper display. The lower display shows the total elapsed time since the start of the timing operation. You can calculate the total amount of time that play was interrupted (lost time or injury time) by subtracting the upper display time from the lower display time.

To set the event time

1. 1. In the Stopwatch Mode, hold down A until the current event time setting starts to flash in the lower display. This is the setting screen.
   • I f the current event time is not displayed, use the procedure under “To reset elapsed time measurement to zero” (page EN-20) to display it.
2. While a setting is flashing, use D (+) and B (–) to change it.
   • You can set the event time in the range of 1 minute to 60 minutes, in 1-minute units.
   • “- -” indicates there is no event time set.
3. Press A to exit the setting screen.

Countdown Timer

With the countdown timer, you can set up to nine start times, which are counted down in sequence one afterthe other. The countdown timer can be used for interval training (for example, three minutes running with INT 1, 1 minute rest with INT 2, five minutes running with INT 3) or for timing an multi- period event (for example, 45 minutes of play with INT 1, 15 minutes rest with INT 2, 45 minutes play with INT 3).

• The watch performs an alert operation (beeper) when any timer reaches zero.
• An alert operation (about one second) is performed when any countdown timer (except for the last one in the series) reaches zero. When the last countdown timer in the series reaches zero, an alert operation is performed for about five seconds.

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.

Graphic Areas
The following describes the information indicated by the three graphic areas in each mode.

Button Operation Tone
The button operation tone sounds any time you press one of the watch’s buttons. You can turn the button operation tone on or off as desired.

• Even if you turn off the button operation tone, the alarm, the Hourly Time Signal, the countdown timer alarm, and the event time alarm all operate normally.

• Holding down C to turn the button operation tone on or off also causes the watch’s current mode to change.
• is displayed in all modes when the button operation tone is turned off.

Scrolling
The B and D buttons are used in various modes and setting screens to scroll through data on the display. In most cases, holding down these buttons during a scroll operation scrolls at high speed. This is true except when the countdown timer number is flashing on the Countdown Timer Mode screen (page EN-26).

Auto Return Features

•  I f you leave the watch in the Alarm Mode for two or three minutes without performing any operation, it changes to the Timekeeping Mode automatically.
• I f you leave a screen with flashing digits on the display for two or three minutes without performing any operation, the watch exits the setting screen automatically.

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 built-in full automatic calendar makes allowances for different month lengths and leap years. Once you set the date, there should be no reason to change it except after you have the watch’s battery replaced.

World Time

• The seconds count of the World Time is synchronized with the seconds count of the Timekeeping Mode.

• All World Time Mode times are calculated from the current Home City time in the Timekeeping Mode using UTC time differential values.

• 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 world-wide scientific standard of timekeeping. It is based upon carefully maintained atomic (cesium) clocks that keep time accurately to within microseconds. Leap seconds are added or subtracted as necessary to keep UTC in sync with the Earth’s rotation.

Illumination Precautions

• I llumination loses power after very long use.
• I llumination may be hard to see when viewed under direct sunlight.
• I llumination turns off automatically whenever an alarm sounds.
• Frequent use of illumination runs down the battery.
