Front Panel Operations
The front panel includes an LCD screen that displays the current status
of the scaler and the scan rate of the current video input signal. You can
also use controls on the front panel to control the image display.
Diagrams of the front panels are shown on page 2-6.
Default screens
By default, the LCD toggles between two screens every four seconds.
One screen displays the product name, and the other shows the output
resolution and frequency (figure 10 shows an example).

toggles between screens similar to those shown in figure 11.

Choosing the input source
To choose an input source, press the input selection button to toggle
through the inputs. The LED corresponding to the selected input lights:
• Input LED 1 — Composite video
• Input LED 2 — Component video
• Input LED 3 — S-video
• Input LED 4 — RGB pass-through video (DVS 150 only)
When the button is released, the input changes and the LCD shows the
current input and signal type (see figure 12). The message appears for
8 seconds, and then changes back to the default screens.

image.
To make an adjustment, do the following:
1. Push the control button that corresponds to the adjustment you
