4.1.4 Focus Button
The Focus button is used to toggle the focus between the Yellow Select Box on the moving map and the
Numerical Information Area (NIA) on the bottom of the moving map. The term focus is used by
software programmers to refer to the item on the screen that is currently active. The item with the
focus is the active item. When the Yellow Select Box has the focus you can move it around on the
screen using the Arrow buttons. When the Numerical Information Area has the focus you can use the
Left and Right Arrow buttons to move through the displayed parameters. The use of the Focus
button is intuitive because the yellow color of the button matches the yellow color of the item on the
screen that has the focus.
Changing the active item on the moving map using the Focus button.
Shifting focus to any item on the screen is temporary. For example, the Numeric Information Area will
lose focus automatically 25 seconds after your last key press. The Yellow Select Box will lose focus 5
seconds after your last key press.
The Focus button also serves another important function. It can be used to exit the setup menus
and return to the moving map display. The Menu button can also be used to exit any menu and
return to the moving map display.
4.1.5 Select Button
The Select button is used to “select” or “enter” or “OK” or “acknowledge” or “confirm” the current
selection. It is located at the center of the keypad and is extended out further than the other buttons
to make it easy to find and activate without looking at the remote. The round shape is different from
all the other buttons – which also makes it easy to find and activate with your thumb.
