Detailed Answer
Block structures inside the dock cause signal blind zones (dock bottom corners, behind blocks). Symptoms: no key response + signal-loss protection stops the machine. Countermeasures: 1. Repeaters to eliminate blind zones; 2. Operating route planning (avoid blind zones); 3. High receiver antenna mounting; 4. Blind-zone marking. LDER's dock coverage solutions include blind-zone elimination; XINGJIA likewise.
