ABOUT THE BACKLIGHT
Pressing Lilluminates the display for about two seconds. If you hold down L, the light
automatically disappears after five seconds.
TELEMEMO MODE
• The backlight of this watch employs an electro-
luminescent (EL) light, which loses its illuminating
power after very long term use.
• The watch emits an audible sound whenever the
display is illuminated. This is caused because the
EL light vibrates slightly when lit. It does not indi-
cate malfunction of the watch.
• Frequent use of the backlight shortens the battery
life.
