The four-channel model is effectively shielded. The mobile signal only blocks the mobile phone signal and does not affect the normal operation of other electronic equipment. Under normal circumstances, the effect is best when used at a place away from the base station. It can work stably for a long time when the power is turned on. The slow-start circuit design can avoid mechanical Sparking phenomenon caused by switch
