Section 3:

Basic Sonar Operation

This section addresses the unit's

most

basic

sonar operations. The in-

structions presented in Sec. 3 follow a chronological order. Sec. 4,

Sonar

Options & Other Features

, will discuss other more advanced functions

and utilities. Material in Sec. 4 is arranged in alphabetical order.

Before you turn on the unit, it's a good idea to learn about the different
keys, the Main Menu, the four Page screens and how they all work to-
gether. BUT, if you just can't wait to get on the water, turn to the one-
