This microphone has a 3-level power switch design. 2. ln using first turn on the receiver and then the transmitter. 3. New battery the power light is in "OFF". The light is "ON" It indicates the battery needs to be replaced. 4. Remember to turn the switch "OFF", When the microphone is not in use in order to save power. ln "STAND-BY" set the switch to the center. SMT is a design of high quality and precise technology. High quality dynamic cartridge is used to produces HI-FI sound, which is soft, broad and deep, most suitable for KTV entertaining. POWER LE D LIGHT (WHEN LESS POWER THE LIGHT IS IN "ON") NOTE: Make sure the power switch is in the "OFF" position when changing or installing new battery. Average life on an alkaline battery is 12 hours. Be sure to use good quality long life 1.5V alkaline battery only. O F F "STAND-BY" function.
