User Instruction
：
(The transmitter enters working mode 3 seconds after switching on.)
1).Use Microphone
：
Make sure the Stereo mode is OFF before using microphone, otherwise the volume will be very low and can’t work normal. Please use the microphone that
comes in this package since we have tested and match them well. If you want to use other microphone, please use good quality ones with cable less than 50cm.
2).Broadcasting
：
Make sure the STEREO is ON when broadcasting audio signals from MP3/Computer/TV/cellphone or other audio equipment, so as to avoid distortion. Use a
good quality audio cable longer than 50cm to connect transmitter with audio device, and adjust transmitter volume to get the best audio quality. Try to stretch the audio cable
as long as possible and keep away from metal objects.
