or the menu system. Rotate these knobs to change picture settings when one of the

Front Panel Operations
The following paragraphs detail the power-up process and then describe the menu system,
the picture adjustments, and selection of executive mode.
Power
Power is automatically applied when the power cord is connected to an AC source. When
AC power is applied, the switcher performs a self-test that blinks all of the front panel
LEDs and then lights only the LEDs for the previously selected output and the tied input.
The self-test also displays the model name, part number, and the firmware version in the
LCD display. After approximately 2 seconds, the LCD reverts to its default display cycle,
alternating between two displays: one showing the inputs selected for outputs 1 and output
2, and the other showing the selected output rates (see figure 16). An error-free power up
self-test sequence leaves all of the LEDs off, with the exception of the selected output’s and
input’s LEDs, off and the LCD cycling through the default displays.
