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 51.
