Safety
Always check that your route is safe. Use the RANGE button to
zoom in and check for hazards that may not be visible on a larger
scale view.
Until you are familiar with interpreting the chart display, take every
opportunity to compare what’s shown on the chart display with your
actual surroundings. Practice harbor and coastal navigation during
daylight hours and in clear weather conditions. You can also use the
simulator mode to gain experience in using your display unit.
Before you use the chart application make sure you have read and
understand Chapter 3:Waypoints.
