USER'S GUIDE 2611
If the P.SAVE indicator is flashing on the display, it means
that the display is blank because the watch's Power
Saving function has turned off the display to conserve
power. Power Saving automatically turns off the display
and enters a sleep state whenever your watch is left for a
certain period where it is dark.
• The initial factory default setting is Power Saving on.
• The watch recovers 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.

Moon / Tide Data Mode
Stopwatch Mode
Home Site Data
Moon phase, tide graph data, and Moon/Tide Data Mode data will not be displayed
properly unless Home Site data (GMT differential, longitude, and lunitidal interval) is
configured correctly.
• The GMT differential is the time difference of the time zone where the site is located
and Greenwich Mean Time.
• The lunitidal interval is the time elapsing between the Moon's transit over a meridian
and the next high tide at that meridian. See "Lunitidal Interval" for more information.
• This watch displays lunitidal intervals in terms of hours and minutes.
• The "Site Data List" and "Lunitidal Interval List" provide GMT differential, longitude,
and lunitidal interval information around the world.
• The following is the initial factory default Home Site data (Tokyo, Japan) when you
first purchase the watch, whenever battery power drops to Level 4, and whenever
you have the battery replaced. Change these settings to match the area where you
normally use the watch.
GMT differential (+9.0); Longitude (East 140 degrees); Lunitidal interval (5 hours,
