This section features a one-page Sonar Quick Reference. (If you've al-
ready jumped ahead and figured out how to install the unit
yourself, and you just can't wait any longer, turn to the Quick
Reference on page 50 and head for the water with your unit!)
When you come to a sonar menu command on the unit's screen, you can
look it up in the manual by skimming over the table of contents, looking it

through the sonar setup options in Section 7.
If you're having difficulty with your sonar, you can find an answer to
the most common problems in Section 5, Sonar Troubleshooting.
