Power Saving
Power saving causes the watch to automatically enter a sleep state to save power whenever the watch 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 its face is blocked from light by your sleeve.
❚ How the sleep state works
There are actually two sleep state levels, a "display sleep state"
and a "function sleep state".
• 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 display sleep state causes the display to go blank.
• 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 display sleep state, analog time
timekeeping and auto signal receive are both performed.
• The watch does not enter the display sleep state if it is in the
Timer Mode or Stopwatch Mode.
• Function sleep state
The function sleep state is triggered whenever the watch is left in
the dark for six or seven days.
• Alarms and the Hourly Time Signal are also disabled while the
watch is in the function sleep state.
Analog time timekeeping and auto signal receive are not
performed while the watch is in the function sleep state.
• Timekeeping functions continue to operate normally in the
function sleep state.
