General Guide

• Press C to change from mode to mode.

• In any mode, press L to illuminate the digital display areas.

If the Power Saving indicator ( ) is flashing, it means that the display is blank because the watch’s Power Saving function has turned it off to conserve power. Power Saving automatically turns off the display and enters a sleep state whenever your watch is left for a certain period in an area where it is dark. If the watch is kept in the dark for a longer period, the analog hands will also stop moving after a few days.

• The initial factory default setting is Power Saving on.

• The watch will recover from the sleep state if you move it

to a well-lit area, if you press any button, or if you angle the watch towards your face for reading.

• See “Power Saving Function” for more information.
