Eagle Electronics 502cDF manual Basic Sonar Operation, Keyboard

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 sonar unit, it is 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 47.
