How to operate the buttons on the Status bar
The Status bar has two types of controls: toggle button and drop-down list button. You
operate the buttons with the trackball module.
Mode button
A mode button selects the operating mode (see
section 6.3). The background color of a mode button is
light-blue when its operating mode is enabled; gray when
disabled. The [NAVI] button is an example of a mode but-
ton.
Drop-down list button
A drop-down list button provides a list from which to se-
lect an option related to the label on the button. The
[Chart Database] button is an example of a drop-down list
button. See the right figure. A drop-down list button has a
list status indicator (a triangle) whose position changes
according to list status.
