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 display. 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 among several displays; one for each
input that shows that input's configuration, and the last showing the selected
output standard (figure 3-3). An error-free power up self-test sequence leaves all of
the LEDs, with the exception of the selected inputs' LED(s), off and the LCD
displaying the default display cycle.
The selected inputs and their size and position on the display, the picture
adjustments, and other current settings are saved in nonvolatile memory. When
power is applied, the latest configuration is retrieved.
