About the backlight

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

• Pressing (D) at any time illuminates the display for about two seconds, 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.

To switch the backlight function on and off
In the Timekeeping Mode, hold down (B) for one or 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.
• 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.
