Press C 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 Day Counter Mode and Telememo Mode, the watch automatically reverts to the normal timekeeping screen. When making settings (except Easy Timer setting), 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.

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. There are ten day counters, each identified by a counter number. You can assign text titles up to eight characters long to each of the 10 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. The page number on the display when you exit the Day Counter Mode appears first the next time you enter the Day Counter Mode.

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.
