ABOUT THE BACKLIGHT
About the Auto Light Switch Function
When the auto light switch function is turned on, the backlight automatically turns on for two seconds under the conditions described below. Avoid wearing the watch on the inside of your wrist. Doing so causes the auto light switch to operate when not needed, which shortens battery life. Moving the watch to a position that is parallel to the ground and then tilting it towards you approximately 40 degrees causes the backlight to illuminate.

4. While the seconds digits are selected (flashing), press D to reset the seconds to �00�. If you press D while the seconds count is in the range of 30 to 59, it is reset to �00� and 1 is added to the minutes. If the seconds count is in the range of 00 to 29, the minutes count is unchanged. 5. While any other digits (besides seconds) are selected (flashing), press D to increase the number or B to decrease it. Holding down either button changes the current selection at high speed. � While the 12/24-hour setting is selected, press D to switch between the two formats. 6. After you set the time and date, press A twice to return to the timekeeping display. � The date can be set within the range of January 1, 1995 to December 31, 2039. � If you do not operate any button for a few minutes while a selection is flashing, the flashing stops and the watch goes back to the timekeeping display automatically.

� Static electricity or magnetic force can interfere with proper operation of the auto backlight function. If the auto backlight does not illuminate, try moving the watch back to the starting position (parallel with the ground) and then tilt it back toward you again. If this does not work, drop your arm all the way down so it hangs at your side, and then bring it back up again. � Under certain conditions the backlight may not light until about one second or less after turn the face of the watch towards you. This does not necessarily indicate malfunction of the backlight. In the Timekeeping Mode, hold down D for one or two seconds to turn the auto light switch function on and off.

Important
� After you change a setting in the above procedure, the watch needs a bit of time to calculate certain information. During this calculation, the patterns in the graphic display move at high speed. Wait until the patterns stop moving before you try to input any further data. � If you set the current time forward one hour for daylight saving time (summer time), be sure to also increase the setting for your difference from Greenwich Mean Time (see �To set location data� below). Of course, you should remember to adjust the other way (by decreasing the difference) when you go back to standard time.

� The auto light switch indicator is shown on the display in all modes while the auto light switch function is on. � In order to protect against running down the battery, the auto light switch function is automatically turned off approximately three hours after you turn it on. Repeat the above procedure to turn the auto light switch function back on if you want. � Pressing B while in the Timekeeping Mode illuminates the display, regardless of the auto light switch's on/off setting.

Caution
� 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 backligfht shortens the battery life. � The watch emits an audible sound whenever the display is illuminated. This is because the EL light vibrates slightly when lit. It does not indicate malfunction of the watch.
