Detailed Answer
Post-drop inspection: 1. Appearance: housing cracks/deformation (affects sealing); 2. Function: test all keys; 3. Antenna: loose/broken; 4. Emergency stop: press-and-reset test; 5. Interior: unusual rattling (loose parts). Lider LD series passes a 1-meter drop test, so ordinary drops are usually fine. A cracked housing must be replaced (breaks IP67 sealing); return to factory if functions are abnormal.
| Appearance | Cracks/deformation |
| Function | Test all keys |
| Sealing | Replace if cracked |
Note:After a drop, test the emergency stop first, then all functions.
