About the backlight

When you switch the backlight function on, the backlight of the watch fl ashes whenever alarm, countdown timer or hourly time signal is sounding.

• Pressing D in any mode illuminates the display, regardless of the backlight's on/ off setting.
• 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 will emit an audible sound whenever the display is illuminated. This is caused by a transistor that vibrates when the EL panel lights up. It 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 stops illuminating whenever an alarm sounds.

To switch the backlight function on and off
In the Timekeeping Mode, hold down E for about two seconds to switch the backlight function on and off. When you switch the backlight function on, an indicator appears on the display as shown.

• The backlight function indicator remains on the display in all modes until you switch the backlight function off.
• The above operation controls operation of the backlight function only. It does not affect operation of audible tones and signals.
