Zooming in and out

To get a closer look at the chart area around your vessel or around the cursor, press the IN key to zoom in. To see a wider area, press the OUT key to zoom out. Each press of the IN or

OUT key approximately halves or doubles the chart scale, respectively.

At the highest detail for a particular chart, you can use the 958 as a precision plotter. When you zoom in past that level, the center of the chart is magnified to fill the screen and all text and symbols are doubled in size. Zooming in still further causes the 958 to remove all chart detail from the screen for safety reasons, leaving only your vessel, its track, user-entered waypoints, and the lat/lon grid.

Chapter 4 - Using the Chart Screen

As a reminder that no charted hazards or nav aids are shown, the 958 displays the words NO CHART multiple times across the screen. Even without any chart data displayed, you can still use the 958 as a precision plotter

NOTE:

If the chart has a radar overlay and if you change the chart’s scale (by zooming in or out), the scale of radar changes to match. If you change the scale of radar, the scale of the chart also changes to match, even if the chart isn’t visible at the time. However, if the radar overlay doesn’t appear on the chart, you can scale the chart and radar separately.

Controlling the cursor on the chart screen

Pressing the CURSOR PAD displays the cursor symbol on the

CHART screen. Further pressing of the CURSOR PAD will move the cursor across the screen. If you have trouble finding the cursor in a busy part of the CHART screen, just look at the sides of the screen for the red cursor pointers: They match up with the cursor.

If you move the cursor right onto an object, such as a displayed waypoint, you will select that object, as indicated by a diamond-shaped box (see left) around the object.

Information about the selected object appears at the bottom of the screen, as shown below.
