 Auto Light Precautions
• Leaving auto light enabled can run down the watch's battery due to frequent
display illumination.
• The auto light may not operate properly when the watch is angled towards your
face from an angle greater than about 15 degrees as shown in the illustration
below.
• Electro-static charge or magnetism can interfere with proper auto
light operation. If this happens, try lowering your arm and then
angle it towards your face again.
• When moving the watch you may note a slight rattling sound.
This is due to operation of the auto light switch, which determines
the current orientation of the watch. It does not indicate
malfunction.
• Auto light will remain enabled for about 6 hours after you turn
it on.
