will degrade performanceand influence thereception.
Wireless microphone effectivedistance within 30meters. In orderto not affectingthe effect, please
do not useover than thevalid range. Whenthe battery decreasedor the environmentradio
interference source signalis too strong,it will shortenthe using distance.
Toachieve the besteffect of singing,the distance ofmouth and microphoneshould be keepin 5-15
cm, and thebest angle is45 degrees.
Insufficient power afterusing long time,the LED willlight up. Pleasereplace the batteryin time.
Please don't usethe same frequencyof microphone tosing at thesame time ina short distance.It
will lead tosilence or interference.
If you buymore than twosets of activespeaker with wirelessmicrophones and wantto use together
at the sametime, please selectstandard frequency ofdifferent varieties. Ifnot, there mustbe 100
meters distance atlease between twosets speaker insame frequency.Soas not tocause interference
and other unnecessarytrouble. Atthe same time,don't put speakerstoo close toVCD/CD/DVD during
