4.1 Switching Inputs
You can switch between connected HDMI devices using two methods:
- Manual Button: Press the 'SWITCH' button on the front panel of the device to cycle through the HDMI inputs.
- IR Remote Control: Use the provided IR remote control to directly select an input (1-5) or cycle through inputs. Ensure the remote has a clear line of sight to the IR receiver on the switch.

4.2 Auto/Manual Switching Mode
The switch supports both automatic and manual input switching. By default, it operates in auto-switching mode, where it automatically switches to a newly activated HDMI source.
- Toggle Mode: To switch between Auto and Manual mode, press and hold the 'SWITCH' button on the device for 3 seconds.
- Auto Mode: The switch will automatically detect and switch to the active HDMI input.
- Manual Mode: The switch will remain on the currently selected input until you manually change it using the button or remote. This mode is useful for setups where devices might send intermittent signals, causing unwanted auto-switching.

4.3 ARC (Audio Return Channel) Function
The ARC function allows audio from your TV's built-in apps or other HDMI inputs on your TV to be sent back to a soundbar or audio receiver connected to the switch's HDMI Input 1. This eliminates the need for a separate audio cable.
- Ensure your TV's HDMI port supports ARC and is enabled in your TV settings.
- Connect your soundbar/audio receiver to the HDMI Input 1 port on the Mrocioa switch.
- Note: This switch supports ARC, but not eARC.
