How to proper use and trouble clearing of Bietrun Wireless Microphone(WXM02,WXM04 ) 

This product doesn't have an echo effect adjustment. If there's feedback due to loud volume causing a squeal, here are some improvement suggestions: 1. Place the microphone away from the speaker's mouth. 2. Lower the microphone volume to around 8-12, with 8 being the minimum. Alternatively, decrease the speaker's MIC volume a bit.
