Viewing Cartography - Humminbird 398ci SI Combo Operation Manual

Viewing Cartography

In the Chart or Combo Views there are several cartography-related functions
that you can access using various keys.
Chart View with Cursor Present,
shown with Optional-Purchase
Navionics® Cartography
Zooming: Press the Plus (+) key to Zoom In and the Minus (–) key to Zoom Out
to see the cartography at different magnification levels. The zoom level is
indicated on the left side of the display. If you zoom in beyond the available
chart data, the display will go into Overzoom mode whereby the last available
chart data is amplified to reflect the level selected. If you zoom in so far that no
cartography is available, a lat/long grid will be drawn instead. Zooming is also
influenced by the Auto Zoom and Auto Range settings. See Chart Menu Tab:
Auto Zoom and Auto Range for more information.
Decluttered Waypoints: When two or more waypoints overlap, or are displayed
close together on a chart view, the screen will automatically declutter—
waypoint names will shorten and the waypoint icons will change into small
blue icons.

Panning: Use the 4-WAY Cursor Control
key to move the chart around on the
display in the direction of the key being
pressed. When you do this, a bull's eye
cursor is drawn at the center of the
screen and is linked to the boat by a gray
line, even if the boat is off the screen. At
the same time, the temperature and
speed boxes in the lower left corner are
replaced with the distance and bearing
from the boat to the cursor position and
the latitude/longitude coordinates of the
cursor.
