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
from Greenwich Mean Time.
Operation Guide 2532
If the SLEEP indicator is 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 puts
the watch into 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.
It can take up to five seconds for the display to turn on.

• Note that you must add one hour to the GMT differential for your time zone
whenever you change to Daylight Saving Time. Subtract one hour when you change
back to Standard 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 5, and whenever
you have the battery replaced. Change these settings to match the area where you
anormally use the watch.
