How Do the K037B/K037 Work with the Receiver?
Can I use 2 of these with one receiver? Can I plug other XLR lav mics into the transmitter?
No, you can't.
Why does the receiver blink green and turn off automatically?
It's just because the batteries run out of power. You can replace them with a new pair of AAA-size batteries.
Is there a way to get a replacement receiver part only for it?
Yes, we sell the lapel mic, headset mic, transmitter, and receiver separately. But contact the sales support to confirm the version of the replacement part.

The transmitter or receiver could not turn on
Use 1.5V Alkaline batteries. Make sure the battery polarity is correct and the battery door of the receiver is closed completely.
The receiver light is green (it doesn't pair with the transmitter)
Change new batteries and follow the resetting process in the video below to pair the devices manually.
The receiver light is red, but there is no sound being projected
Check if the plug of the receiver is loose (visible); change to another frequency; use the mic in the recommended distance (60 feet), and test the mic with another device if possible.
