ABOUT THE BACKLIGHT (MODULE 2321 ONLY)
� Hold down L to illuminate the display for about 2 seconds. The backlight is disabled while an input screen (with a flashing setting) is on the display. � The backlight of this watch employs an electro-luminescent (EL) light, which loses its illuminating power after very long term use. � Frequent use of the backlight shortens the battery life. � The watch emits an audible sound whenever the display is illuminated. This does not indicate malfunction of the watch. � The illumination provided by the backlight may be hard to see when viewed under direct sunlight. � The backlight automatically turns off whenever an alarm sounds. � When the backlight is turned on, it blinks whenever the minute hand moves. This is normal, and does not indicate malfunction of the watch.
