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.
Auto Display
Auto return features
If you leave a screen with a flashing setting 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 C button is used in various modes and setting screens to scroll through data on the display. In most cases, holding down this button during a scroll operation scrolls through the data at high speed.
Initial Screens
When you enter the World Time or Day Counter Mode, the data you were viewing when you last exited the mode appears first.
World Time
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 between the time zone where the city is located and Greenwich Mean Time.
GMT differential is calculated by this watch based on Universal Time Coordinated (UTC) data.
Backlight Precautions
The backlight uses an LED (light-emitting diode) and a light guide panel that cause the entire display to glow for easy reading in the dark. In any mode, press L to illuminate the display for about three seconds.
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.
Frequent use of the backlight shortens the battery life.
Auto Display continually changes the contents of the digital display.
To turn off Auto Display
Press any button (except for L) to turn off Auto Display. This returns to the Timekeeping Mode.
To turn on Auto Display
Hold down B for about two seconds until the watch beeps.
Note that Auto Display cannot be performed while a setting screen is on the display.
