How the sleep state works
• Display sleep state
The display sleep state is triggered whenever the watch is left
in the dark for three or four days.
• The display goes blank in the display sleep state.
Alarms and the hourly time signal continue to operate normally,
while the watch is in the display sleep state.
Even when the watch is in the sleep state, digital-analog time
synchronization and auto signal receive are both performed.
• Function sleep state
The function sleep state is triggered whenever the watch is left
in the dark for four days.
• Alarms and the hourly time signal are also disabled while the
watch is in the function sleep state.
• In the function sleep state, analog timekeeping is disabled, so
digital-analog time synchronization is not performed.
• Digital timekeeping functions continue to operate normally in
the function sleep state.
❚
To recover from the sleep mode
Place the watch in an area that is well-lit, press any button, or
angle the watch towards your face to illuminate the display using
the Auto Light (“To illuminate the face with the auto light switch”).
• It can take up to two seconds before the display re-appears after
you place the watch in a well-lit area.
❚
To turn power saving on and off
See the procedure under “To configure Home Time Zone settings”
for information about turning off power saving.
Leaving the watch in a drawer or anywhere else it is dark can
cause the power saving mode to trigger in order to conserve
battery power.
• The analog hands are not shown in the face illustrations shown in this User’s Guide.
