Self Troubleshoot before proceed any further.
Please include the test result when resorting for email support.
1.Using fresh batteries for transmitter. After switching it on, does mic screen turn solid on?
2.If receiver indicator blinks green, use the same freshness of AAA batteries. Then does it stay solid red?
3.If indicator still flashes green, does reset help?
4.If reset doesn't work, before reset, are both receiver and transmitter off? During reset: does mic screen blink and 564MHz appear?
5.For smartphone, is it connected through the included PHONE adapter. For camera, is it CAMERA adapter? If speaker/smartphone/camera volume is turned up in a decent level?
Q: I can’t pair them. they just didn't work.
Q: How can I avoid hissing?
A: Compatibility and interference issue are major cause for the hiss noise.
Except for the interference from the environment (mobiles, computer, TV, game console, even the lights), there are some other factors.
For example some input jack on the camcorder is very sensitive that will cause the hiss. A powerful, loaded desktop PC would produce very strong EMI. A defective adapter or poor connection between connecting cables will also cause hiss.
So please try to test the mic with other speaker directly (not using any adapter) and compare the result. Then you will know whether the hiss is caused by the compatibility issue.
Q: How can i reduce feedback??
A: Before the setup, turn down the volume control of speaker.
When plugging receiver in, do not place the mic directly in front of speaker.
During the use, a)Slowly adjust the volume setting of speaker. b)Instead of speaker, please position the microphone close to your mouth for loud and clear sound. c)And keep the mic at least 9 feet away from speaker for perfect effect. d)Try to use the headset mic if the lapel mic causes the feedback noise.
Q: What type of battery does it use?
A: The transmitter (the body-pack device) needs 2pcs AA 1.5V batteries, while the receiver (the part being plugged into the speaker) uses 2pcs AAA 1.5V batteries.
Q: How long is the battery life of this K037/K037B?
A: Generally it could last 5 to 6 hours with fresh alkaline batteries or fully charge rechargeable batteries. But different batteries vary a bit because of different capacities. We suggest you to try other brand new batteries to find the most durable ones. And please turn off both the transmitter and receiver to save power between services. Also, take out the batteries if you don’t use the mic for a long time.
Q: Can I use 2 of these with one receiver? Can I plug other XLR lav mics into transmitter?
A: No, you can't.
Q: Is the mic compatible with my device?
|Speaker with 1/4" MIC input
It will perfectly fit. Though you still may need to change the speaker when using with external mic. For example, to switch the "Line In" to "Microphone", or you need to switch from FM Mode to other proper mode for using the mic.
Note: ECOXGEAR GDI-EXBLD810 is not compatible
|Speaker with only Line-in
|It requires the signal that has higher level of power than a mic signal has. Mis-match will result in low sound. So we don't recommend to use the mic with the small speakers.
|Make sure there is 3.5mm microphone input jack on your camera. Because some cameras only have an "audio out" jack, not an "audio in" jack. And whatever kind of camera USB jack is not compatible, which does not allow audio input.
|The (1/4'' to 3.5mm TRS) included adapter is for cameras only, it is NOT compatible with smartphone.
You'll need to buy a different adapter cable from our site if you want to use the mic with smartphone that still has 1/8" jack.
Note: make sure the transmitter has paired with the receiver before you plug the system to any device. (Receiver light remains RED, that means connected.)

Q: Do I need speakers or an amp?
A: Sorry it doesn't come with speaker or have built-in speaker, so you will need to find a speaker or PA system. We suggest to use the mic with the speaker that has 1/4'' mic input and mic volume control.
Q: Which speaker is fits?
Q: The receiver blinks green and turn off automatically!
A: It's just because the batteries run out of power. You can replace them with a new pair AAA size batteries.
Q: Doesn't work. Any help with this?
|Transmitter or receiver could not turn on
|Use 1.5V Alkaline batteries. Make sure the battery polarity is correct and the battery door of receiver is closed completely.
|Receiver light is green, meaning it doesn't pair with the transmitter
|Change new batteries and follow the resetting process in video below to pair the devices manually http://bit.ly/k037037bproblemsolving
|Receiver light is red,but there is no sound projecting
|Check if the plug of the receiver is loose (visible); change to other frequency; use the mic in the recommended distance (60 feet) and test the mic with another device if possible.
Q: Why the volume was so low （not loud enough）?
A: We recommend to connect the mic to the 1/4'' speaker input designed for a mic connection. If your speaker has only 3.5mm line or aux in which requires the signal that has higher level of power than a mic signal has, the mic will be low and hard to be heard.
The sensitivity of the lapel mic and headset mic are the same. The reason why the headset mic is louder is because it could be positioned much closer to the mouth than the lapel can be. So I suggest you to turn up the mic volume when you change to the lapel mic.
Q: The headset mic picked up my breathing. Any suggestions?
A: It's an unidirectional mic, so it will primarily pick up voice of person right in front of it. We suggest to adjust the position of the headset mic, 30 to 45 degree angle off axis to your mouth, then it won't pick up too much breath pops.
Q: Is there a way to get a replacement receiver part only for it?
A: 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.
