Unity 4650 User's Manual
3.2 Operation from Front Panel
Front-panel
The U4650 front panel (Figure 3.2) includes the
layout
following four main parts: a liquid crystal dis-
play (LCD), six pushbuttons, eight LED indica-
tors, and the front-panel audio and video monitor
ports. Essentially all control available through
the network or terminal is also available from
the front panel.
The front-panel LCD (1, see LCD screen rela-
tionships on page 41) supports unit monitoring
and control by displaying screens containing sta-
tus information, menu navigation pointers, and
parameter input fields. Each LCD screen has a
label or heading on the first row and informa-
tion, parameters, or prompts on the second row
which may cycle through multiple messages
depending on the context.
The six pushbuttons (2) are your means of com-
manding the U4650 from the front panel. Use
the four arrow buttons to navigate through menu
screens and parameter selections and to scroll
through available choices or characters when
editing an input field. Press the ENT (Enter) but-
ton to select menus (downward navigation), to
open editable input fields, or to commit edited
parameters to the U4650. Press ESC (Escape) to
exit an input field without saving the entry or
selection. ESC also provides upward navigation
through the menu structure to the home screen.
The eight front-panel LEDs (3) provide status
information about your U4650 and its processes.
See Table 7: Front-panel LED Indicator
Descriptions on page 45 for complete details.
(Two additional LEDs are located on the rear
panel and provide Ethernet status indications.)
At far right are the video port and audio port (4)
included for monitoring from the front panel.
