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 turns off automatically whenever an alarm sounds.
• Frequent use of the backlight shortens the battery life.

The Data Bank Mode lets you store up to 25 records, each with a name (up to eight
characters) and a phone number (up to 12 digits). Entering the Data Bank Mode displays
a screen that shows the mode name (DB) and remaining memory capacity (number of
records) for a few moments. After that, the record you were viewing the last time you
exited the Data Bank Mode will appear. Anytime you input a new record, all records will
be sorted automatically into alphabetic sequence on the name.*
