Avoid strong impacts, squeezing, or abnormal forces on the device.
Do not hold or adjust the device with one hand on the side arms; avoid excessive twisting or pulling of the side straps.
Third-party accessories (e.g., earmuffs) can be used if they do not interfere with the side arms' functionality. Improper use or heavy accessories may affect weight distribution, strain the straps, or even break the side arms.
