Backlight Precautions

The backlight uses an LED (light-emitting diode) and a light guide panel that cause the entire display to glow for easy reading in the dark.

In any mode, press B to illuminate the display for about one second.

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.

Frequent use of the backlight shortens the battery life.
