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
The Auto Display feature of this watch automatically
cycles through the available color patterns.
To turn off Auto Display
Press any button to turn off Auto Display.
Doing so also performs the corresponding button
function as described below.
A or B: Enters 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

screen.
Data and Setting 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 through the data at high speed.
Initial Screens
When you enter the Telememo or Alarm Mode, the data you were viewing
when you last exited the mode appears first.
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 L 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.
