About the Auto Light Switch
Turning on the auto light switch causes illumination to 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 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 startle 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 traffi c
accident
and serious personal injury.
