Note: 1. Since the DC resistance of the original coil is very small, the current can not be too large, the power‑on time should not be too long, and the power supply voltage should not exceed DC4V.2. Pay attention to protect the plastic frame, and don't let it subject to strong collision or fall on the ground.3. After the instrument is used, it should be placed in a clean, dry and ventilated place without corrosive gas.4.Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering.
