(*1) When the supplied battery spacers are used.
(*2) Transmission range is measured on a quiet street with Personal PA System loaded with fresh batteries.
Range varies depending on surrounding environmental conditions, such as battery consumption, ambient noise levels, wind direction and obstacles. Reference standard: JEITA (Japan Electronics and Information Technology Industries Association) TT-4501D
(*3) Battery life during voice output usage represents the period of time when the Personal PA is continuously, used with the volume control set to a position that does not cause feedback.
Reference standard: JEITA (Japan Electronics and Information Technology Industries Association) TT-4501D
(*4) Battery life during AUX stereo input represents a value actually measures when music is continuously reproduced with a commercial audio player connected to the auxiliary (AUX) input terminal. It varies depending on the connected external equipment’s volume output or the type of music source.
(*5) 0dB = 1V
(*6) Adjust the volume of the auxiliary (AUX) input at the connected external device.
(*7) Volume during monaural operation is smaller than during stereo operation.
(*8) THE 120cm (3.94ft) length is when the Belt is stretched out to its maximum extent. When worn, consider a Belt length of 100 cm (3.28ft) (of waist size when clothes are worn) as a rule-of-thumb standard.
