1. OPERATIONAL OVERVIEW
The basic function of a video plotter is to record and plot ship's track, using position data fed from
a navigation device which is built in the display unit or is installed separately.
Once the equipment is properly installed, you need do no more than turn on the power to plot
ship's track. Of course, your equipment does much more than just plot ship's track, and it is our
intention to guide you along in the use of your equipment with instructions that start at a basic
level and proceed forward in a logical manner.
In this chapter you will learn the most basic functions of your equipment, from turning on the
power to how to read the navigation data display.
