  • Lightweight body keeps hands from tiring even during long hours of use (170 g with 2 alkaline batteries).
  • Infrared light emission intensity is adjustable at 2 levels.
  • Two selectable channel frequencies.•Antibacterial treatment.
  • Employs an electret condenser microphone unit.
  • Low-battery indicator.
  • Color stickers supplied to distinguish one unit from other wireless microphones.
