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.

Auto light switch on indicator

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

Tur ning 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).
