After operation the microphone must be switched off as well. Otherwise the batteries will soon be exhausted. In order to avoid untune consumption of the inner battery: if pilot lamp of the wireless microphone (1)remains lighted, it means that the battery has no more power: (2)the lamp must flash only for the time of the switching -on; this indicates that the microphone works well. 2. INSTALL BATTERY: PLS. make sure the positive/negative before you replacement batteries. We congratulate you for the choice of this excellent professional apparatus microphone which will give you outstanding results at the high fidelity. The microphone suit for school speech, meeting speech, teachers and performer on the stage. When switches the power switch to "on" position, then the power indicator lights, indicate the apparatus is on. When switches the power switch to "off " position, then the power indicator lights, indicate the apparatus is off. FEATURES: "STAND-BY" funciton. Steel net based to prevent from rolling.
