Power
Apply power by connecting a power cord between an AC source and the rear panel
power connector. The switcher performs a self-test that flashes the front panel
button indicators green, red, and amber and then turns them off. An error-free
power up self-test sequence leaves all input, output, and control buttons either unlit
or showing background illumination and the Video button and the Audio button
lit.
The current configuration and all presets are saved in non-volatile memory. When
power is applied, the most recent configuration 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
