About the Backlight

• Press L to illuminate the display for about 2 seconds.

• 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 may emit 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.

• The backlight of Module 2338 illuminates both the digital display and analog face. The backlight of Module 2337 illuminates the digital display only. The backlight of Modules 2374, 2384 and 2705 illuminates the analog face only.
