Lto illuminate the display for about 1 second.
•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 indi-
cate malfunction of the watch.
•The backlight automatically turns off whenever an alarm sounds.

what direction the moon is seen.
Example In the example at left, the moon has passed the meridian.
If you look above the moon near the equator, the moon is
seen at west. In Northern hemisphere the moon is seen at
west from the south. In Southern hemisphere, the moon is
seen at west from the north.
