3. Pairing and Connection

The RIJER system is designed for plug-and-play operation with automatic pairing. Once both the Transmitter and Receivers are powered on and connected to their respective devices, they should automatically establish a connection within approximately 30 seconds. The indicator lights on both units will blink during pairing and become solid once a stable connection is made.

Operating Instructions

1. Basic Operation

Once the Transmitter and Receivers are successfully connected, the video and audio from your source device will be automatically mirrored or extended to the connected displays. No additional software or configuration is typically required.

2. Transmission Modes

The system supports different display modes depending on your operating system settings:

• Copy Mode (Mirror): Displays the same content on all connected screens, including the local loop-out display.
• Extended Mode: Allows you to extend your desktop across multiple screens, providing more workspace. This mode is typically configured through your computer's display settings.

3. Optimal Performance

For optimal transmission range and stability, ensure the antennas on both the Transmitter and Receivers are positioned vertically and unobstructed. The system utilizes 2.4/5.8G dual-band technology to maintain a stable signal.
