Section 3:

Basic Sonar Operation

This section addresses the unit's most basic sonar operations. The instructions 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 together. BUT, if you just can't wait to get on the water, turn to the one-page Quick

Reference on page 55.
