About auto light
While auto light is enabled, illumination will turn on whenever you
position your wrist as described below in any mode.
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.
Warning!
• Always make sure you are in a safe place whenever you are reading the display of the watch
using auto light. 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 auto light does not startle
or distract others around you.
• When you are wearing the watch, make sure that auto light is disabled before riding on a bicycle
or operating a motorcycle or any other motor vehicle. Sudden and unintended operation of auto
light can create a distraction, which can result in a traffi c accident and serious personal injury.

snooze alarm. The snooze alarm will sound every fi ve minutes up to
