X515C DF & X510C Manual - Lowrance

Section 3: Basic Sonar Operation
This section addresses the unit's most basic sonar operations. The instructions
presented here in Sec. 3 follow a chronological order. Sec. 4,
Sonar Options & Other Features, will discuss options and other more
advanced functions and utilities. The 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 Sonar Menu, the five Page options 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 43.
