Detailed Answer
Construction site dust (cement, sand) is severe; dust protection measures: 1. IP6X fully dust-tight (LIDEER IP67); 2. Sealed key gaps (silicone keypad + sealing rings); 3. Dust cap on the charging port; 4. ePTFE vent membrane (prevents internal dust buildup); 5. Regular cleaning (air blow + soft brush). Dust buildup can stick keys, cause wear, and affect heat dissipation.
