Power
Apply power by connecting the power cord to an AC source. When AC power is
applied, the switcher performs a self-test that fl ashes the front panel LEDs and then
turns them off. An error-free power up self-test sequence leaves the RGBHV LED
and the Audio LED on, and all other LEDs unlit.
The current confi guration and all presets are saved in non-volatile memory. When
power is applied, the most recent confi guration is retrieved. The previous presets
remain intact.
If an error occurs during the self-test, the switcher locks up and does not operate.
If your switcher locks up on power-up, call the Extron S
