Why is there no blind zone alert when the target falls within the blind zone?

Answer: Suspended installation mode is enabled. Switch to standard installation mode to activate blind zone alerts (default blind zone 0.3 m, adjustable downwards).

Suspended installation function: In complex echo scenarios, echoes within the blind zone are suppressed; the radar prioritizes targets outside the blind zone for distance calculation. Modify via upper computer or Bluetooth.

Configuration commands:

• Adjust blind zone: AT+BLINDZONE=0.05 (minimum 0.05 m, adjust per site conditions)

• Switch installation mode: AT+INSTALLTYPE=0 (0 = standard installation, 1 = suspended installation)

Bluetooth menu: App Parameter Configuration – Installation Mode – Blind Zone Distance
