If your location is not included in the preset city codes, select the preset city code that is in the same time zone as your location.

•Note that all of the times for the World Time Mode city codes (page E-23) are displayed in accordance with the time and date settings you configure in the Timekeeping Mode.

•All of the operations in this section are performed in the Tide/Moon Data Mode (page E-8).

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.

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-49) 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-19) 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-21) to change it.

•Use the Tide Data Screen to specify the Tide Data time. You can use D to change the displayed time in one-hour increments. The Tide Data time is scrolled within the current date only. Scrolling past midnight does not change the date.
