Garmin GPSMAP 190-00683-00 - Manual (Page 16)

Using the GPSMAP 378/478
The advanced keypad system on the GSPMAP 378/478 is
designed to allow you to select options and enter data quickly and
conveniently. As you progress through this owner’s manual, you
are directed to press a specific key or highlight a field on the screen.
When you are directed to press a key, you should press and quickly
release the key. If the key needs to be held down for a period of time
to start a secondary function, the instructions will tell you to do so.
When a field is selected on the screen, it is highlighted in yellow.
The following terms are used throughout this manual:
• Highlight—move the highlighted area on the screen up,
down, left, or right with the ROCKER to select individual
fields. Moving the highlight to a given location allows you to
make a selection, begin data entry, or scroll through a list.
• Field—the location on a page where data or an option can
be shown and entered. Select (highlight) a field using the
ROCKER to begin entering data or selecting options.
• On-screen button—use the ROCKER to highlight a button
and press ENTER to select the button.
• Scroll bar—when viewing a list of items too long to appear
on the screen, a scroll bar appears along the right side of
the list. To scroll through a list, press up or down on the
ROCKER.
• Default—the factory setting saved in the unit’s memory. You
can change the settings, and you can also revert to the factory
(default) settings when you select Restore Defaults.
