� The time on the screen may not appear to stop immediately when you press a button to stop timing or to perform a split operation. Despite this, the time recorded by your button operation is accurate.

� If you leave the watch in the e-DATA MEMORY, City Temperature, or Alarm Mode for two or three minutes without performing any operation, it automatically changes to the Timekeeping Mode. � If you leave a screen with flashing digits or a cursor on the display for two or three minutes without performing any operation, the watch automatically saves any settings you have made up to that point and exits the setting screen.

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.

Hand Setting
Minute hand Hour hand

When the analog setting does not match the time shown on the digital display, use this mode to correct the analog setting. � This watch features separate digital and analog timekeeping. Note that the digital time and analog time are independent of each other, and must be set separately.

Initial Screens
When you enter the e-DATA MEMORY, World Time, or City Temperature Mode, the data you were viewing when you last exited the mode appears first.

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 2039. � 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.

To set the analog time 1. Hold down A while in the Hand Setting Mode until L/set starts to flash. 2. Use B and D to set the analog time. � Each press of D advances the hands 20 seconds. � Pressing B while holding down D causes the hand setting to change at high speed, even if you release the buttons. Press any button to stop.
� The analog time setting does not stop automatically when it reaches the current time. You must stop the hands manually. � Note that the hands can be advanced only and cannot be moved back. Take care so you do not go past the setting you want to make. 3. After you set the analog time, press A to exit the setting screen. � Depending on your timing when you operate the D button, the above operation can cause the minute hand timing to become late. If this happens, repeat the above operation to correct the minute hand timing.

World Time
� The seconds count of the World Time is synchronized with the seconds count of the Timekeeping Mode. � The world time that appears in the lower part of the Timekeeping Mode screen always uses 24-hour format, regardless of the watch�s current 12/24-hour setting. � The current time in all World Time Mode cities is calculated in accordance with the Greenwich Mean Time (GMT) differential for each city, based on the current Home City time setting in the Timekeeping Mode. � The GMT differential is the time difference of the time zone where the city is located from Greenwich Mean Time. � GMT differential is calculated by this watch based on Universal Time Coordinated (UTC) data.

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.

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.

Auto Display
Auto Display continually changes the contents of the digital display.

To turn off Auto Display
Press any button (except for B) to turn off Auto Display.

To turn on Auto Display
In the Timekeeping Mode, hold down C for about three seconds until the watch beeps. � Note that Auto Display cannot be performed while a setting screen is on the display.
