Getting Started
Selecting Options
The GPSMAP 178C Sounder’s advanced keypad system is designed to allow for fast, convenient
selection of navigation options and data entry. The Getting Started Tour introduces you to the keypad
and provides a ‘hands-on’ lesson in using the GPSMAP 178C Sounder. We strongly encourage you
to follow the Getting Started tour before using your unit for actual navigation. The GPSMAP 178C
Sounder Quick Reference Guide contains helpful tips on using the unit and performing various naviga-
tion tasks.
Selecting Options and Entering Data
You can select and activate options and enter data to customize the GPSMAP 178C Sounder to fi t
your requirements. You can use the

ARROW KEYPAD

names and numbers in data fi elds, and activate your selections.

the list of options requires movement of the cursor, which is identifi ed as “highlighting”, selecting
or choosing an item in a list or a fi eld (box) on a page.
