Markings on magnetic pump
Thread Content
May I ask? What does this mean? It’s drawn on the magnetic pump
A red circle with a black heart inside was drawn, and then a diagonal line was added? This is to indicate that people with pacemakers should not approach. Because magnetic pump has strong magnetic components, it is dangerous to get too close. If it is a yellow background with a horseshoe-shaped magnet drawn on it, this is to indicate the presence of a strong magnet.
Okay, thank you\ud83d\ude0a
