Important Safety Notes
- TX/RX antennas must be connected at all times. Operating without antennas may cause permanent damage to the device.
- Adequate heat dissipation is required for continuous operation.
- Received signal strength at any port must not exceed +10 dBm, or permanent damage will occur.
- Recommended antenna spacing: > 0.2 m between antennas on the same module; > 1 m between modules (applies to both powered and unpowered modules).

Auto Frequency Control
On startup, the module attempts to establish a network using the last stored frequency point. If unsuccessful, it automatically scans for available frequencies. The center node re-selects frequencies upon loss of synchronization, while access nodes initiate a new search process to find and join an available network.
Auto Power Control
The center node operates at maximum rated transmit power. Access node transmit power is automatically adjusted based on real-time signal quality, optimizing power efficiency and reducing interference across the network.
