How to use XTE alarm (INTO mode)
When your boat is cruising parallel to an object or area you want to avoid, for
example, a reef, sandbar, etc., use the XTE alarm (INTO) to alert you when your
boat is within a certain distance to the object or area.
1. On the FURUNO plotter, create a route which runs parallel to the area you
wish to avoid.
2. Set the XTE alarm (INTO) range such that it is the distance to the edge of the
area plus some allowance.
When your boat nears the area by the distance set above the XTE alarm sounds
to alert you.
