Tide Information screen.

The Tide Information screen displays daily tidal data for this station on this date at the present time. The graph at the top of the screen is an approximate view of the tidal range pattern for the day, from midnight (MN) to noon (NN) to midnight (MN). The dotted line across the graph is the Mean Lower Low Water line (MLLW).

The height scale on the top right side of the graph changes, based upon the maximum range of the tide for that day. The MLLW line also ad- justs its position as the height scale changes.

You can look up tidal data for other dates by changing the month, day and year selection boxes. To select another date:

1.Use ← → to highlight month, day or year, then press ENT.

2.Use ↑ ↓ to select the desired month, day or year and press ENT. To clear the information screen, press EXIT.

Navionics Charts

Your unit can also display Navionics electronic charts on MMCs. Like NauticPath, Navionics charts contain tide and port service information.

NOTE:

The primary operational difference between a NauticPath chart and a Navionics chart is the way the chart data is set up for dis- play. NauticPath charts are ready for display as soon as they are inserted into the unit. Navionics charts must be inserted into the unit, then selected as a Map Choice option in the Map Data menu.

To display a Navionics chart:

1.Install the Navionics MMC in the memory card compartment and turn on the unit. (For full card install instructions, see Sec. 2.)
