FLO Measure Soft Key
The FLO Meas (measure) soft key at the top of the main screen provides information
concerning the transmitter system distortions and exciter corrections for them. This infor-
mation is given in three screens. They are:

LCD Display Flow Chart
Navigation is started from the main screen by lightly touching Status, Setup, Fault, or the
spectrum display. Refer to Figures 3-2, 3-4, and 3-3 for the main screen, setup, and status
flow charts.
spectrum display. Refer to Figures 3-2, 3-4, and 3-3 for the main screen, setup, and status
flow charts.
• From any screen, other than the Main screen, Home returns to the Main screen.
• From any screen, Fault brings up the System Status screen.
• From any sub screen within Setup, pressing Back returns to the System Setup screen.
• From any sub screen within Status, pressing Status returns to System Status screen,
and pressing Back on some status screens returns to the next higher level of screen.
• Some System Status and Setup sub sections are composed of several (two or more)
sub screens. Within these sections, Next and Prev (previous) sequentially walks
through the sub screen selections.

• Some status sub screens include a diagnostic screen. This screen provides additional
information for the screen in question.
