س: ما هي الاحتياطات الخاصة عند استخدام جهاز التدليك KY1081 على أجزاء مختلفة من الجسم؟

ج:

The noise when a single part is working is ≤ 50 dB (similar to the sound of turning pages quietly), and when multiple parts are turned on simultaneously, the noise is ≤ 55 dB. When the air pressure and vibration functions work together, the massage effect is enhanced but the energy consumption increases. It is recommended to use different parts based on the battery life requirement.
