When the oscilloscope is connected to power, press the Power key   at the 
lower-left corner of the front panel to start the oscilloscope. During the start-up 
process, the oscilloscope performs a series of self-tests. You can hear the 
switching sound of the relay. After the self-test, the welcome screen is 
displayed. The "Current Options" dialog box will be displayed if your instrument 
currently has installed the trial versions of the options. From this dialog box, 
you can view the type, the name, the version, and the remaining trial time of 
the option currently installed. The instrument is installed with the trial versions 
of the options before leaving factory. Its remaining trial time is about 2,000 
minutes.
