INTRODUCTION
Keypad Usage
The GPSMAP 235 Sounder’s advanced
keypad system is designed to allow for fast, con-
venient selection of navigation options and data
entry.
The getting started tour will introduce you to
the keypad and provide a ‘hands-on’ lesson in
using the sounder. We strongly encourage you to
take the getting started tour before using your
unit for actual navigation and fishing.
The Quick Reference Card contains helpful
tips on using the unit and performing various
navigation and sounder tasks. It’s a good idea to
keep the Quick Reference Card nearby whenever
you’re operating your new sounder.
