Illumination
Two LEDs (light-emitting diodes) illuminate the face of the
watch for easy reading in the dark. The watch’s auto light
switch automatically illuminates the face 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.
• You can specify 1.5 seconds or 3 seconds as the
illumination duration.
Auto light switch
on indicator
To illuminate the face of the watch manually
In any mode (except when a setting screen is on the display), press B to illuminate
the face of the watch.
• The above operation turns on illumination regardless of the current auto light switch
setting.
About the Auto Light Switch
Turning on the auto light switch causes the face to illuminate, whenever you position
your wrist as described below in any mode. Note that this watch features a “Full Auto
LED Light”, so the auto light switch operates only when available light is below a
certain level. It does not illuminate the face under bright light.
Moving the watch to a position that is parallel to the ground and then tilting it
towards you at more than 40 degrees causes illumination to turn on.
• Wear the watch on the outside of your wrist.
• See “Illumination Precautions” for other important
information.
