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.
•
See “Illumination Precautions” for other important
information.
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 more than 40 degrees causes illumination to turn on.
•
Wear the watch on the outside of your wrist.
Warning!
•
Always make sure you are in a safe place whenever you are reading the face
of the watch using the auto light switch. Be especially careful when running or
engaged in any other activity that can result in accident or injury. Also take
care that sudden illumination by the auto light switch does not surprise or
distract others around you.
•
When you are wearing the watch, make sure that its auto light switch is turned
off before riding on a bicycle or operating a motorcycle or any other motor
vehicle. Sudden and unintended operation of the auto light switch can create a
distraction, which can result in a traffic accident and serious personal injury.
To turn the auto light switch on and off
In any mode (except when a setting screen is on the display), hold down
B
for about
two seconds to toggle the auto light switch on (
displayed) and off (
not
displayed).
•
The auto light switch on indicator (
) is on the display in all modes while the auto
light switch is turned on.
•
The auto light switch turns off automatically whenever battery power drops to Level 3.
