To activate this function:
AUTOMATIC CHECK Turns the Route Checking feature On or Off. Turn the Automatic Route Check on after
you have created a new Route, or if you inserted a new Waypoint, deleted, moved or
edited any Waypoint in a saved Route to confirm the Route can be safely navigated.
ROUTE WIDTH Allows you to select the width from the left and right of the Route leg where the CP590
will check to confirm navigation threats. See the picture below. The default for this
selection is 0.04Nm.
DEPTH LIMIT Allows you to select the water depth in the Route width area so the CP590 can check and
confirm underwater threats. It checks if some objects with the depth attribute (like
Shallow Water, Dredged Areas, Diffusers, Obstructions, Pingos, Production Installation
and Wrecks) are above this depth level. Only if the depth attribute is above the depth limit
are they found and considered as dangerous. See the picture below. The default setting
is 10ft.
ACCURACY Defines a segment length into which a leg of the Route is divided in order to execute the
search for dangerous objects with better accuracy. When accuracy is maximal, a
segment length is the shortest. When accuracy is minimal, a segment length is the
longest. Selects among Minimum, Low, Medium, High and Maximum. See the picture
below. The default setting is Medium.
ROUTE CHECK REPORT Shows the list of the dangerous objects found on the charts crossed by the Route.

NOTE
Although the functionality is called Route Check, it can also be activated when the navigation is set
to a single point (like DSC, MOB, Mark). In the case of checking a single point towards which the
navigation is started, the leg for which the Route Check is executed is defined by the current position
(the leg’s starting point) and the destination point (the leg’s ending point).
