About the backlight
In any mode, hold down B to illuminate the display.
• Note that pressing B not only turns on the backlight, but it also performs any other
function assigned to the B button in the mode you are in. See the explanations for
each section for details on the B button operation.
• If you want to turn on the backlight simply to illuminate the display the watch in the

• The backlight of the watch employs an electro-luminescent (EL) light, which loses
illuminating power after very long use.
• The illumination provided by the backlight may be hard to see when viewed under
direct sunlight.
• 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.
