features and functions of this watch.

digital display.

Color Pattern Precaution
Note the following points about the different color patterns used for the display
of this watch.
• When using the red on black or red on blue color pattern, red figures may be
difficult to read from some viewing angles.
• When using a pattern with a blue or black background, the backlight may be
difficult to see.
Auto Return Features
• After you perform any button operation (except for the backlight button) in any
mode, pressing C returns directly to the Timekeeping Mode.
• If you leave the watch in the e-DATA MEMORY 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.
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.
Timekeeping
• With the 12-hour format, the P (PM) indicator appears to the left of the hour
digits for times in the range of noon to 11:59 p.m. and the A (AM) indicator
appears to the left of the hour digits for times in the range of midnight to
11:59 a.m.
• With the 24-hour format, times are displayed in the range of 0:00 to 23:59,
without any indicator.
• The year can be set in the range of 2000 to 2039.
• The watch’s built-in full automatic calendar automatically 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.
e-DATA MEMORY Management
e-DATA MEMORY can hold up to 356 characters total, while each record can
contain up to 95 characters. This means that 60 records can be stored in e-
DATA MEMORY when each record contains five characters of text. Note that
the color pattern of the e-DATA MEMORY Mode remaining memory screen
changes as shown below as remaining capacity changes.

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.
