Determine the necessary operation mode for the switcher (the default mode is normal). Choose auto-input switch mode (D) to automatically switch to the highest numbered input with active sync pulses. Choose normal mode (C) to manually change the input. For details on how to change modes, see “Selecting Auto-input Switch Mode” in chapter 2, “Installation and Operation.”

Step 2

Select an input.

•If you are using normal mode, select the desired input by pressing and releasing its input button (E). The LED (G) for the selected input lights.

To switch to another input, press a different input button.
