Operating Instructions
The VWRHar HDMI Switch offers two primary methods for switching between connected HDMI sources:
Manual Switching (Button on Device)
- Locate the "Select" button on the front of the HDMI Switch unit.
- Press the button repeatedly to cycle through the input ports (IN 1, IN 2, IN 3).
- The corresponding LED indicator light (1, 2, or 3) will illuminate to show which input is currently active.
Remote Control Switching
- Point the IR remote control towards the HDMI Switch unit.
- Press the corresponding number button (1, 2, or 3) on the remote to directly select the desired HDMI input port.
- The LED indicator on the switch will confirm the selected input.
Automatic Switching
- The switch is designed to automatically detect and switch to a newly activated HDMI source. For example, if you turn on a gaming console connected to IN 2 while IN 1 is active, the switch may automatically switch to IN 2.
- If multiple devices are active, the switch will typically remain on the last manually selected or automatically detected active input. Manual or remote switching can override automatic selection.

Image: This illustration highlights the two primary methods for selecting inputs: using the included IR remote control or pressing the physical switch button on the unit itself.

- Storage: Store the device in a cool, dry place away from direct sunlight and extreme temperatures.
- Handling: Avoid dropping the device or subjecting it to strong impacts.
- Ventilation: Ensure the device has adequate ventilation and is not covered, as this can affect heat dissipation.
