## 5. Engineering Risks & FAQ
- **Caution**: 
- **Caution**: 
- **Caution**: 

### Q: What is the primary function of an operator display in LMI systems?
**A**: The operator display provides real-time visual feedback of load weight, radius, angle, and safety limits to help equipment operators make informed decisions and prevent overload situations.

### Q: What materials are used in operator display construction for durability?
**A**: Operator displays typically feature polycarbonate or acrylic housing for impact resistance, with LCD or LED panels protected by durable lenses to withstand harsh industrial environments.

### Q: How does the operator display integrate with LMI systems?
**A**: The display connects via interface connectors to the LMI's sensors and controller, receiving real-time data that's processed by the driver circuit/controller board and presented on the display panel.
