1. Brief introduction
Microsound can sense human activity information with the technology of infrared pyroelectric principle. When
someone enters the induction range, it can accurately identify the human activities. It looks like a cat's eyes, not
depending on light. Even in the dark environment, it can work stably and reliably, overcoming the shortcomings of
light induction.
It is small and exquisite, easy to carry and has a beautiful sound. Human body induction triggering, large
induction range, sensitive. Intelligent triggering, no need to have manual operation. One of the main
characteristics is using our company’s mature technology of human body induction. When detecting the human
body passing it will give warm prompts, warnings and welcomes or other voice at the first time. According to the
different applications, different audio files can be replaced at any time.
This product has been used in the exhibition hall, subway station, elevator, gated prompt, automatic
loudspeaker, advertisement and other promotional occasions.

★Note:
1. When switch on, wait about 20S, then it can work normally. Within 4 meters, when people or animal walk by, it
will trigger the sensor to play voice.
2. Each time, after triggering to play voice, you need to wait 2S, then it can trigger again to play voice.
3. Each time, after triggering, go out of the induction range and enter the range again, then it can have a better
effect of the next trigger.
4. In B mode, you only need to short press key A or B to select audition of the triggering voice, need no other
operations.
5. Key function is only valid during the process of voice playing. If no voice play, it’s invalid to press key.
6. If plug in the power, please remember to remove the batteries to avoid unexpected accidents.
5. Audio download
It’s easy to replace audio files. Just use USB cable to connect to computer, here will appear a drive. You just need
to copy audio files into this drive.
★Note:
1. The audio file size should be not more than internal FLASH capacity. Only support MP3 audio format.
2. After copying is complete, sometimes play a section voice. When finishing the voice play, 3 seconds later, it
can trigger and play again.
You can copy any voice, tones, music, into this product, as long as the format is MP3, within memory capacity.
Besides, you can make your own personalized voice.
6. Brief operation introduction
How to replace voice files:
1. Convert the voice into MP3 format.

2. Connect to computer by USB cable. Computer will automatically appear a “removable disk”.
3. Format the “removable disk”.
4. Open it by double-clicking, choose voice files to copy.
Infrared principle: the temperature of induction area rises suddenly, then trigger induction.
Only suitable for indoor use.
If environment temperature is over 30℃, infrared induction distance will be shortened, which is a normal
phenomenon.
If environment temperature is over 37℃, infrared induction will be invalid, because human body temperature is
37℃, so it cannot sense.
Induction distance too short?
Reason 1: low battery (you can use regular alkaline batteries)
Reason 2: environment temperature too high, influences its induction distance.
Reason 3: after playing a section voice, there will be 3 seconds interval. Wait 3s, then it can trigger and play.
Reason 4: when testing, if parallel with infrared ray, it will be unable to trigger effectively. You should walk form the
left of device to the right, forming a cross with infrared ray, then it can trigger.
Normal induction distance is 0-3 meters. If the temperature is high, induction distance is about 2 meters.
If there is electric fan or air conditioner blowing, influence on the temperature of induction area, it can trigger to
play voice.
So you’d better to choose the environment to test where there is no electric fan or air conditioner blowing.
7. Installation
Side wall mounted
About 1.5 meters above the ground is the best. About 1 meter far from the door-frame. Use the mounting holder
to fix the device, toward the door, 45°(see picture).
Installed on the top of the door
About 2 meters above the ground is the best. Lay across, paralleled with door-frame. If door-frame is wide,
installed crosswise.
Detailed installation depends on the environment, just installed where people pass by. It can be used for
reminding, sales promotion, doorbell, visitor welcome, etc.
