Note: This procedure is especially useful to change from the Operator or Service levels
to the User level after executing an Operator or Service level command.
If the control panel is accessed from the Operator (O) or Service (S) level, and no
activity has occurred for 15 minutes, it will return to the initial screen ( Figure 22 on
page 60), and to the default security level.
