Sec. 3: Basic Sonar Operation; Keyboard - Lowrance LCX-18C Operation Instructions Manual

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-
page Quick Reference on page 49.
