Front Panel Operations
The following paragraphs detail the power-up process and then describe input
selection, preset selection, Auto-Imaging, and then details the menu system, the
picture adjustments, and selection of executive mode.
Power-on indications
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 inputs previously selected
for the preview output (blinking LED[s]) and program output (solid LED[s]). 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 selected program
and preview inputs and their rates, and the other showing the selected output rate
(figure 3-4). An error-free power up self-test sequence leaves all of the LEDs, with
the exception of the selected input’s LED, off and the LCD displaying the default
display cycle.
The selected preview and program inputs, the picture adjustments, and other
current settings are saved in nonvolatile memory. When power is applied, the
latest configuration is retrieved.
