BACKLIGHT FUNCTION

FLASH indicator

• 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 transformer that vibrates when the EL panel lights up. It does not indicate malfunction of the watch.

• The backlight automatically turns off whenever an alarm sounds.

To manually turn on the backlight

Pressing L in the Timekeeping, Stopwatch or Alarm Mode causes the backlight to turn on for about two seconds. Pressing C in the Beat Counter Mode also causes the backlight to turn on for a fixed amount of time.

• The backlight normally stays on for about two seconds and then turns off automatically. When the EL alarm is turned on, however, the backlight stays on for about five seconds instead of two seconds.

• The above operations turn on the backlight, regardless of the current EL alarm settings.

A backlight that uses an EL (electro-luminescent) panel

causes the entire display to glow for easy reading in the dark. An EL alarm feature can be turned on so the backlight flashes whenever an alarm or hourly time signal sounds.

• The FLASH indicator is shown on the display in all modes while the EL alarm is on.

Note

• The backlight of the watch employs an electro-liminescent (EL) light, which loses illuminating power after very long use.

The Beat Counter Mode can be used to produce an audible signal in accordance with BPM (beats per minute) value,

which is like a digital metronome that can be used for a variety of different musical applications.

• The letters “BPM” stand for “beats per minute” in this manual.
