About the Backlight

Hold down x L to illuminate the display for about 2 seconds. The backlight is disabled while an input screen (with a ﬂ ashing setting) is on the display. The backlight of this watch employs an electro-luminescent (EL) light, which loses its x illuminating power after very long term use. Frequent use of the backlight shortens the battery life. x The watch emits an audible sound whenever the display is illuminated. This does x not indicate malfunction of the watch. The illumination provided by the backlight may be hard to see when viewed under x direct sunlight. The backlight automatically turns off whenever an alarm sounds. x
