Power Saving

Power Saving causes the watch to enter a sleep state automatically in order to save power whenever it is left in the dark. The Power Saving feature of the watch is turned on at the factory.

•Note that the watch may also enter the sleep state if the watch is blocked from light by your sleeve.

How the sleep state works

•Display sleep state

The display sleep state is triggered whenever the watch is left in the dark for about one hour between the hours of 10 p.m. and 6 a.m.

•The watch does not enter the sleep state if it is in the Timer Mode or Stopwatch Mode.

• The display sleep state causes the display to go blank, except for a flashing Power Saving indicator. Alarm, hourly time signal, and Timer Mode progress alert and time up alert operate normally in the display sleep state.

•Function sleep state

The function sleep state is triggered whenever the watch is left in the dark for six or seven days.

•The Power Saving indicator stops flashing and remains on the display. Alarm, hourly time signal, and Timer Mode progress alert and time up alert do not operate in the function sleep state. In the function sleep state, 2-hour barometric pressure readings and auto receive also are not performed.

•Digital timekeeping functions continue to operate normally in the function sleep state.

❚To recover from the sleep state

Place the watch in an area that is well-lit, press any button, or angle the watch toward your face to illuminate the face of the watch using the full auto light switch (“Positioning Your Arm Correctly”).

•It can take up to two seconds before display figures re-appear after you place the watch in a well-lit area.

❚To turn Power Saving on and off

See the procedure under “To configure Home City settings” for information about turning off Power Saving.

Leaving the watch in a drawer or anywhere else it is dark can cause Power Saving to trigger in order to conserve battery power.
