Functional Buttons
The displayed Functional Buttons vary depending on the stage of operations.
Functional buttons can be used to navigate menus, to save or clear
diagnostic data, to exit scanning and to perform a number of other control
functions. The use of these buttons will be discussed in detail in the following
sections of the corresponding test operations.
4.3.2 Screen Messages
Screen messages appear when additional input is needed before
proceeding. There are three main types of on-screen messages:
Confirmation, Warning, and Error.
Confirmation Messages
This type of messages usually displays as an “Information” screen that
informs you when you are about to perform an action that cannot be
reversed or when an action has been initiated and your confirmation is
needed to continue.
When a user-response is not required to continue, the message displays
briefly.
Warning Messages
This type of messages displays a warning that a selected action may result
in an irreversible change or loss of data. The typical example of this is the
“Erase Codes” message.
Error Messages
Error messages display when a system or procedural error has occurred.
Examples of possible errors include a disconnection or communication
interruption.
4.3.3 Making Selections
The Diagnostics application is a menu driven program that presents a series
of choices. As a selection is made, the next menu in the series displays.
Each selection narrows the focus and leads to the desired test. Tap the
screen to make menu selections.
