When a connected HDMI source device is powered on or begins playback, the switch may automatically detect the active signal and switch to that input. This functionality depends on the CEC compatibility and settings of your connected devices.
- インジケーターライト: Observe the LED indicators on the front panel to identify the currently active input source.
