About the backlight

When you switch the backlight function on, the backlight of the watch flashes

whenever alarm (page E-10), countdown timer or hourly time signal is sounding.

• Pressing D at any time 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.

E-9

To switch the backlight function on and off

function on and off. When you switch the backlight function on, an indicator appears
