background.

• For the sake of simplicity, the sample displays in this manual do not show the analog hands of the watch.

• Button operations are indicated using the letters shown in the illustration.

• Each section of this manual provides you with the information you need to perform operations in each mode. Further details and technical information can be found in the “Reference” section.

Digital Time and Date

Use the Timekeeping Mode to set and view a digital display of the current time and date. When setting the digital time, you can also configure settings for summer time (Daylight Saving time or DST), your Home City code (the code for the city where you normally use the watch), and the 12/24-hour format.

• 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 digital time, it is important that you select the correct city code for your Home City. 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 digital time and date settings you configure in the Timekeeping Mode.

• After you correctly set your Home City time and date, you can set the watch up for timekeeping with a different city code simply by changing the Home City code in the Timekeeping Mode.

Countdown Timer

The countdown timer can be set within a range of one minute to 60 minutes. An alarm sounds when the countdown reaches zero. The countdown timer also has an auto-repeat feature and a progress beeper that signals the progress of the countdown.

Module 3750

Minutes

Module 4314

Auto-repeat

When auto-repeat is turned on, the countdown automatically restarts from the countdown start time when it reaches zero. If left running, the countdown is repeated a total of eight times, after which it stops automatically. When auto-repeat is turned off, the countdown stops when it reaches zero and the display shows the original countdown start time.

• Pressing D while an auto-repeat countdown is in progress pauses the current countdown. You can resume the auto-repeat countdown by pressing D, or you can press A to reset to the countdown time starting value.

Countdown Timer Beeper Operations

The watch beeps at various times during a countdown so you can keep informed about the countdown status without looking at the display. The following describes the types of beeper operations the watch performs during a countdown.

Countdown End Beeper

The countdown end beeper lets you know when the countdown reaches zero.

• When the progress beeper is turned off, the countdown end beeper sounds for about 10 seconds, or until you press any button to stop it.

• When the progress beeper is turned on, the countdown end beeper sounds for about one second.

Progress Beeper

When the progress beeper is turned on, the watch uses beeps to signal countdown progress as described below.

• Starting from five minutes before the end of the countdown, the watch emits four short beeps at the top of each countdown minute.

• 30 seconds before the end of the countdown, the watch emits four short beeps.

• The watch emits a short beep for each of the last 10 seconds of the countdown.

• If the countdown start time is six minutes or greater, the watch emits a short beep for

each second of the final 10 seconds before the five-minute point is reached. Four short beeps are emitted to signal when the five-minute point is reached.

To configure the countdown timer

• All of the operations in this section are performed in the Countdown Timer Mode, which you enter by pressing

Seconds

Configuring the Countdown Timer

The following are the settings you should configure before actually using the countdown timer.

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.

raphic

The following describes the information indicated by the graphic in each mode.

World Time

• The World Time Mode times are calculated from the current Home City time setting in the Timekeeping Mode, using the Greenwich Mean Time (GMT) differentials associated with each city code.

• The GMT differential is a value that indicates the time difference between Greenwich Mean Time and the time zone where a city is located.

• GMT differential is calculated by this watch based on Universal Time Coordinated (UTC) data.

Backlight Precautions

The backlight uses an EL (electro-luminescent) panel that causes the entire display to glow for easy reading in the dark. In any mode, press B to illuminate the display for about two seconds.

• The electro-luminescent panel that provides illumination loses power after very long use.

• The illumination provided by the backlight may be hard to see when viewed under direct sunlight.

• The watch may emit an audible sound whenever the display is illuminated. This is due to vibration of the EL panel used for illumination, and does not indicate malfunction.

• The backlight automatically turns off whenever an alarm sounds.

• Frequent use of the backlight shortens the battery life.
