When using this watch to take readings while boating or engaging in any other activity during which losing your way can create a dangerous or life-threatening situation, always be sure to use a second compass to confirm direction readings.

The longitude, lunitidal interval, Moon phase indicator, and tide graph data that appears on the display of this watch is not intended for navigation purposes. Always use proper instruments and resources to obtain data for navigation purposes.

This watch is not an instrument for calculating low tide and high tide times. The Tide Graph of this watch is intended to provide a reasonable approximation of tidal movements only.

In addition to normal timekeeping, use the Timekeeping Mode to set the current time and date.

The Moon phase indicator shows the current Moon phase.

The tide graph shows the current tidal movements.

Important!

The watch cannot produce correct Moon phase or tide graph data unless the Timekeeping Mode current time and date settings, as well as city data settings (GMT differential, longitudes, and lunitidal interval) are all correct.

Having the batteries replaced causes the Timekeeping Mode’s time/date and city data settings to revert to their initial factory default settings. Use the following procedure to set the current time and date, and to make city data settings.

To reset the seconds count to zero

1.In the Timekeeping Mode, hold down A until the second’s digits start to flash, which indicates the setting screen.

2.Press E to reset the seconds count to 00.

Pressing E while the seconds count is in the range of 30 to 59 resets the seconds to 00 and add 1 to the minutes. In the range of 00 to 29, the minutes count is unchanged.

3.Press A twice to exit the setting screen.
