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 Alarm or Time Setting Mode (without changing any setting), hold down B. After viewing the display contents, be sure to press M to change to the Timekeeping Mode.

• 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.
