RCVD indicator will disappear
from the display each day when
the first auto receive operation
of the day is performed.

Tide/Moon Data
In the Tide/Moon Data Mode, you can see the tide at a specified time for the tide site
you selected and the current date’s moon phase for your Home City. You can specify a
date and view tide and moon data for that date.
• See “Moon Phase Indicator” (page E-78) for information about the moon phase
indicator and “Tide Graph” (page E-82) for information about the tide graph.
• All of the operations in this section are performed in the Tide/Moon Data Mode
(page E-10).
Note
• It takes about two seconds to calculate tide graph data. You will not be able to
display a setting screen while data calculation is in progress.
• Moon age is calculated to an accuracy of ±1 day.
• You can view the current tide and moon age graph in the Timekeeping Mode (page
E-10).
E-35
Tide Data
The Tide Graph that appears first when you enter the Tide/Moon Data Mode shows
the data at 6:00 a.m. for your currently selected tide site on the current date, according
to the Timekeeping Mode. From there you can specify another time on the same date.
•
If the tide data is not correct, check your Timekeeping Mode settings and correct them
if necessary. See “To configure tide site settings” (page E-75) for more information.
• If you feel that the information shown by the Tide Graph is different from actual tide
conditions, you need to adjust the high tide time. See “Adjusting the High Tide Time”
(page E-37) for more information.
Moon Data
The moon phase and moon age information that appears first when you enter the
Tide/Moon Data Mode shows the data at noon for your currently selected Home City
on the current date, according to the Timekeeping Mode. After that you can specify
another date to view data.
• If the moon data is not correct, check your Timekeeping Mode settings and correct
them if necessary.
• If the moon phase indicator shows a phase that is a mirror image of the actual moon
phase in your area, you can use the procedure under “Reversing the Displayed
Moon Phase” (page E-39) to change it.

• On some days, there are two high tides. With this watch, you can adjust the first high
tide time only. The second high tide time for that day is adjusted automatically based
on the first high tide time.
Reversing the Displayed Moon Phase
The left-right (east-west) appearance of the Moon depends on whether the Moon is
north of you (northerly view) or south of you (southerly view) as you view it.
You can use the procedure below to reverse the displayed Moon phase so it matches
the actual appearance of the Moon where you are located.
• To determine the viewing direction of the Moon, use a compass to take a direction
reading of the Moon at its meridian passage.
• For information about the Moon phase indicator, see “Moon Phase Indicator” (page
E-78).
