Operating Instructions
The ROOFULL HDMI Switch offers multiple methods for selecting your desired input source:
1. Manual Switching:
Press the "Switch" button on the front panel of the unit to cycle through the connected HDMI input sources (IN 1, IN 2, IN 3, IN 4, IN 5). The corresponding green LED will light up to indicate the active input.
2. Remote Control Switching:
Use the included IR remote control for convenient switching from a distance (within 33 feet). Point the remote towards the IR receiver on the front panel of the switch.
- Press the numbered buttons "1" through "5" to directly select the corresponding HDMI input.
- Use the "Up" and "Down" arrow buttons to cycle sequentially through the inputs.
- The "ON/OFF" button controls the power of the switch.
3. Auto-Switching Functionality:
The switch supports an auto-switching feature that detects the voltage of connected source devices. When enabled, if the currently active device is turned off (not in standby mode), the switch will automatically attempt to jump to another active device.
Important Note on Auto-Switching: Some devices, such as PS5/4/4 Pro, Amazon Fire TV, Apple TV, Xbox One/S/Series X, and Nintendo Switch, may continue to emit a weak voltage even when powered off. This can prevent the auto-switching function from correctly identifying and switching to another active device. In such cases, manual or remote switching will be required.
