Safety & Compliance

Important Safety Instructions:

Avoid Port Strain: When connecting heavy or stiff long-distance HDMI cables, ensure the coupler is supported and not hanging freely to prevent bending the internal metal pins.
Align Connectors Straight: Always insert the HDMI male cables straight into the coupler ports; forcing a cable at an angle can permanently damage the internal contact points.
Keep Ports Clear of Dust: Store the coupler in a clean, dry environment when not in use, and check the female ports for dust or debris before inserting cables to ensure a secure connection.
