About the backlight
When you switch the backlight function on, the backlight of the watch fl ashes
whenever alarm (page E-10), countdown timer or hourly time signal is sounding.
Pressing

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
x
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
x
direct sunlight.
The backlight automatically stops illuminating whenever an alarm sounds.
