| Usage Precautions | |
| A. Ensure flux is completely dry before soldering to prevent quality degradation. Pay attention to flux application amount. | |
| B. Do not immerse trimmer potentiometers in solvents. Contact us if cleaning is necessary. | |
| C. Avoid applying excessive force to terminals, sliders, or wiper contacts during PCB insertion and assembly to prevent deformation and poor contact. Exercise extra caution with the wiper mechanism on open-type models. | |
| D. Store away from high/low temperatures, high humidity, and corrosive gases. Pay special attention to long-term storage. | |
| E. Be mindful of stacking pressure on products during storage. | |
| F. Implement a First-In, First-Out (FIFO) inventory management system. | |
