958 Operator’s Manual, Rev. A
Chapter 1 - Getting Started
If your vessel is moving, the symbol will point in the direction
of your course over ground. This direction may be different
from your heading. The vessel symbol shows your actual
direction of travel over the bottom, not the direction you’re
headed. If your vessel isn’t moving, the 958 can’t determine
your COG, so the direction of the vessel symbol won’t mean
anything.
The scale of your first view is about 128 nautical miles (nm)
from edge to edge. To see more details about your position,
press the
IN
key. To see more area and less detail, press the
OUT
key.
Rotating the chart
To change the chart-viewing angle from north-up to course-up
to heading-up to leg-up, cycle through the choices by pressing
the
ROTATE
key.
The current angle is shown at the bottom
half of the
key.
Displaying other
information
You can set up your 958’s
CHART
screen to display your
current route, your track history, nearby waypoints or
avoidance points, a lat/lon grid, a radar overlay, or other chart
details. For details, see see ”Setting up the chart screen”
starting on page 53.
Clearing a GPS or
WAAS alarm
If the 958 doesn’t acquire GPS or WAAS signals within two
minutes, you’ll see a flashing
NO GPS
alarm icon on the lower
right side of the screen. This means the 958 has an alarm
message that needs your acknowledgement: Press the
STAR
function key (twice if the echo sounder is installed) to display
the
ALARMS
screen.
