Illumination

Auto light switch on indicator

An LED (light-emitting diode) illuminates the face of the watch for easy reading in the dark. The watch’s auto light switch turns on illumination automatically when you angle the watch towards your face.

The auto light switch must be turned on (indicated by the auto light switch on indicator) for it to operate.

See “Illumination Precautions” (page E-77) for other important information about using illumination.

To illuminate the display manually

In any mode (except a setting mode), press B to turn on the illumination for about one second.

The above operation turns on illumination regardless of the current auto light switch setting.
