Backlight Precautions

The backlight uses an EL (electro-luminescent) panel that causes the entire display to glow for easy reading in the dark.

• 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.

• Frequent use of the backlight shortens the battery life.

Use the Timekeeping Mode to view the current time and date.

• Day of the week is displayed as follows.
