## Questions & Answers

**Q: I just received my hy929.   the instructions are so very vague.   not enough as to know what to do.  are there more instructions some place else?**
A: Dear friend
Hi again
Please first charge the device for about 5 hours. when you plug in the charger, the device's red indicator lights up, and when the charging is complete, the red indicator lights out.
Normally when you rotate the locator of the device, the device will turn on, and then you can hear the sound,(If it still has no sound,please replace another earphone to try).
Please make sure the microphone and earphone plugs are fully plugged into the device. Insert them firmly and make sure the plugs are in good contact. 

Please note a very important technique to use:
When you put the round microphone close to the wall or the door, be sure to keep your hand still. don't move anything, Otherwise it makes noise because the microphone is very sensitive. it needs a highly sensitive microphone to hear what's going on inside the walls,please understand. 
You just need to keep your hand still and then it can work well

Please try again carefully. if have questions,please tell me 
Thank you very much 
Deng

## Customer Reviews

### ⭐⭐⭐⭐⭐ Powerful listening device
*by M***R on September 18, 2024*

This thing really works i was able to hear my kids talking through wall but the real reason I bought it was to locate underground water leaks. Haven't got to use it yet but if it does work it could be a lucrative tool

### ⭐ Works okay and looks nice.. but it can't record, so it's being returned
*by J***S on August 24, 2019*

I think this device works pretty well when it comes to sound detection, and it even looks and feels like a high quality build. My biggest complaint is that it doesn't record.. there's nothing in the instruction booklet about the recording feature, and there's nothing on the device itself about recording. There's literally only one bullet-point in the product description at the top, and there's only one word: Recorder - and this is why I spent the extra $30 or so for this one. Since it doesn't record, I'm returning this one and found another one on Amazon for about $8.Two things I didn't like about the functionality: one, the wall sensor will not sit flush (I was using it to listen thru my floor, in addition to the wall). Meaning, the internal spring that pushes the little needle out is so strong, you have to really push it down hard to keep it from moving or pushing itself back up. Second, you can easily injure your eardrums and have permanent hearing loss from this product. The volume is able to get extremely loud, and there is no safety feature to protect your ears from sharp, loud noises. I was left with my ears ringing badly just because the sensor moved a little while I was holding it against the wall, and the scraping sound was amplified so loud, it really is dangerous. There needs to be a sound dampening feature to protect against random and unexpected super loud sounds, caused simply by scooting the sensor a little bit while on the wall. And one more thing, I really wish the instruction booklet was written in English, that would have helped a lot!By the way, I've included a picture of the heavy wall sensor for you to see. The manufacturers printed the words "coniact miorophone" on it. I'm not sure what that means, it almost appears to be Latin, but Google translate came up with no translation results for these two strange words. The instruction booklet is written in the same language, thus I was not able to read or understand any of it. It appears to be written in some type of old English dialect or Latin based language.

### ⭐⭐⭐ Does not record audio as-is. Read on:
*by L***S on March 12, 2021*

I do like this product, it works well. I recommend using a dab of hot glue to attach the contact microphone to the wall, making sure not to use too much glue and sticking on the center needle. this will reduce the extra noise from your hand holding it.ALSO! if you look at the side, you will notice there is an opening for an SD card. a regular SD card will not work. there is another piece for this device that will allow you to record. it fits in the opening, I had to look for it on Aliexpress. and it is only $10 plus shipping. So I ordered that and am waiting, then I can update this review.
