About the Auto Light Switch
Enabling 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 face of 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 disabled 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.
Note
• This watch features a “Full Auto LED Light”, so the auto light switch operates only when available light
is below a certain level. Illumination does not turn on under bright light.
• The auto light switch is always disabled, regardless of its on/off setting, when any one of the following
conditions exists.
