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 Home City on the
current date, according to the Timekeeping Mode. From there you can specify
another date or time.
• If the tide data is not correct, check your Timekeeping Mode settings and
correct them if necessary.
• 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-76) 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.
