Figure 3-30 Built In Tests Screen
The BIT (built in tests) soft key is found on the right side of the System Status screen,
shown in Figure 3-5. When the BIT soft key is pressed, see Figure 3-30, a sub window
appears. The message in this window is “Starting BIT requires exciter to be muted.” If the
Ok soft key is pressed, the exciter RF output is reduced to zero. If the cancel soft key is
pressed the exciter continues to function in the previous mode. When the Built In Test
screen is exited, the exciter operation resumes in its previous mode.
