- Manual Switch: Press the "Select" button on the front panel of the device to cycle through the HDMI input sources (IN1, IN2).
- IR Remote Control: Use the provided IR remote control to directly select the desired HDMI input (buttons 1 and 2). The remote also allows you to switch between 2CH and 5.1CH audio modes, and activate/deactivate ARC.

7. ARC Function
The Audio Return Channel (ARC) feature allows audio from your TV to be sent back to the HDMI switch, and then extracted to your sound system via the optical, coaxial, or analog audio outputs. This is useful for smart TV apps or broadcast TV audio.
How to use ARC:
- Ensure your TV's HDMI port supports ARC. Connect your TV's HDMI (ARC) port to the HDMI OUT port of this switch using an HDMI cable.
- Connect your soundbar, speaker, home theater, or A/V receiver to the switch's optical (SPDIF), coaxial, 3.5mm, or L/R audio output using the appropriate cable.
- Activate the ARC function on the switch using the "ARC" button on the device or the remote control.
Note: When ARC is active, your TV remote may not control the volume of the external audio system. Volume adjustment will typically be done via your soundbar or amplifier's remote.
