This chapter explains how to use and display non-radar information that may 
be available from other units connected to your system. It also explains how to 
use the man overboard (MOB) function. You can use this chapter with the 
radar display set to simulator mode, or on the water after you have installed 
and set up your 

hsb

 (PLUS) series Pathfinder Radar system.

In order to use these functions, you need the following additional data from 
equipment connected to your system via a SeaTalk, NMEA or 

hsb

 link:

This chapter covers the following topics:

•

Changing the heading mode of the radar picture

•

Using marks

•

Man Overboard (MOB)

•

Cursor echo 

Note: Until you are familiar with interpreting the radar display, you should take 
every opportunity to compare the radar’s display patterns with visual targets, 
such as other vessels, buoys and coastal structures. You should practice har-
bour and coastal navigation during daylight and in clear weather conditions.
