Press B to change from mode to mode. Pressing L in any mode illuminates the display for about 3 seconds. If you do not perform any operation for a few minutes while a setting screen (with flashing digits) is on the display, the watch automatically exits the setting screen. If you do not perform any operation for a few minutes in the Day Counter Mode or Telememo Mode, the watch automatically reverts to the normal timekeeping screen. When making settings, note that you can scroll only forward, you cannot scroll back. This means that if you go past the setting you want, you must scroll through all of the available settings again until the one you want reappears.

To set the time and date

1. While in the Timekeeping Mode, hold down A until the seconds digits flash on the display, indicating the setting screen. 2. Press B to move the flashing in the sequence shown below. Seconds Day DST Month City code Year Hour Minutes

The World Time Mode shows the current time in 40 cities (27 time zones) around the world. The lower part of the display shows either the day of the week and day, or the month and day. The format used is the one you select in the Timekeeping Mode before entering the World Time Mode. � For full information on city codes, see the �CITY CODE TABLE�. � The time setting of the Timekeeping Mode and the World Time Mode are synchronized, except for the daylight saving time (summer time) setting. Whenever you change the time setting for any city in the Timekeeping Mode, the settings of all World Time cities are changed accordingly. � The World Time Mode has its own daylight saving time (summer time) setting.

To select a World Time City and view its time
In the World Time Mode, press C to scroll forward through the city codes (time zones). Holding down C scrolls at high speed. � You can set up an alarm in the Alarm Mode so it operates based on the current time in a city you specify in the World Time Mode.

3. While the seconds setting is selected (flashing), press C to reset it to 00. If you press C while the seconds setting is in the range of 30 to 59, the seconds are reset to 00 and 1 is added to the minutes. If the seconds setting is in the range of 00 to 29, the minutes count is unchanged. � While the DST� setting is selected (DST on indicator is flashing), press C to toggle it on (ON) and off (OF). � The DST on/off setting you make for the Timekeeping Mode does not affect the World Time Mode. � While the city codes setting is selected, use C to scroll thorough the available codes until the one you want to use as your home time city is displayed. � For full information on city codes, see the �CITY CODE TABLE�. 4. While any other setting is selected (flashing), press C to increase it. Holding down C changes the setting at high speed. 5. After you make the settings you want, press A to exit the setting screen. � The day of the week is automatically set in accordance with the date. � The date can be set within the range of January 1, 2000 to December 31, 2039. � The watch�s built-in full automatic calendar automatically makes allowances for different month lengths and leap years. Once you set the date, there should be no reason to change it except after the replacement of the watch�s battery. � Daylight Saving Time (DST), which is also sometimes called �summer time� advances the time for one hour, as is the custom in some areas during the summer. Remember that not all countries or even local areas use Daylight Saving Time.

Daylight Saving Time (DST)

Daylight Saving Time automatically advances the time setting by one hour from Standard Time. You cannot make individual Daylight Saving Time settings for each city code (time zone). Turning on Daylight Saving Time affects all World Time time zones. Remember that not all countries or even local areas use Daylight Saving Time.

To switch between Standard Time and Daylight Saving Time
In the World Time Mode, hold down A toggle between Daylight Saving Time and Standard Time. Hold down A.

DAY COUNTER MODE
The Day Counter Mode lets you count the number of days from the Timekeeping Mode�s current date to a specific target date. This watch has five day counters. You can assign text titles up to eight characters long to each of the five Day Counters. Whenever the date specified by any one of the day counters matches the date of the Timekeeping Mode (regardless of the day counter�s year setting), the DAYS indicator flashes on the Timekeeping Mode. In the Day Counter Mode, the DAYS indicator flashes on the screen of the particular day counter whose date matches the date of the Timekeeping Mode. The initial default date for all Day Counters is January 1, 2001.

ABOUT THE BACKLIGHT
� Press L to illuminate the display for about three seconds. � The backlight of this watch employs an electro-luminescent (EL) light, which loses its illuminating power after very long term use. � Frequent use of the backlight shortens the battery life. � The watch emits an audible sound whenever the display is illuminated. This does not indicate malfunction of the watch. � The illumination provided by the backlight may be hard to see when viewed under direct sunlight. � The backlight automatically turns off whenever an alarm sounds.
