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 (except when a setting screen is on the display), press B 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.

Daylight Saving Time (DST) Setting

Daylight Saving Time (summer time) advances the time setting by one hour from Standard Time. Remember that not all countries or even local areas use Daylight Saving Time.

	2. Hold down Afor about one second to toggle between
	Daylight Saving Time (DST indicator displayed) and
	Standard Time (DST indicator not displayed).

•The DST indicator will appear on the display whenever you display a city code for which Daylight Saving Time is turned on.
