5. Example of Wiring Connection
Note: When the device is powered on, there is about 5 seconds delay time (LED keeps flashing), which was
designed for paring a remote control during such a duration. After this 5 seconds, the device will be into
standby and ready to work. Also the LED will stop flashing at the same time. Users can just ignore this,
because the remote control has been already paired with the board at our factory.
6. Guide for Operation of Remote Control
Please just leave these terminals alone.
They’re designed for other purposes.

Note: By default, the device is set up to work in the first mode “single playback once on demand”.
6.1. Further Explanation for the Work Modes
1). Single playback once on demand
In this mode, short press one key or two/three keys constantly within a second for direct playback of the associated
audio file. For example, if you want to play the 1st audio file, just simply short press the numeric key ‘1’, then the
device will play the 1st audio file. If you want to play the 678th audio file, just quickly short press the numeric keys ‘6’,
‘7’, and ‘8’ in a sequence within a second, then the module will play the 678th audio file. When the audio file has
played its entirety, the device will stop. In this way, you can direct play back as many as 999 audio files.
2). Single loop playback on demand
In this mode, the device works in the same way as the above mode, but when the audio file has played its entirety, it’ll
continue to play the audio file again and over again in a loop.
3). Repeat all
In this mode, press any numeric key (0-9) on the remote control to start. It’ll play the audio files one after another in a
loop.
4). Random playback
In this mode, press any numeric key (0-9) on the remote to start. It’ll play the audio files in random. When an audio
file finishes playing, another random audio file will continue to play.
6.2. Audio Files Loading/Updating
If the total size of all your audio files is less than 8MB, you can directly load them onto the internal memory of the
device. If they’re larger than 8MB, please use a micro SD card or USB flash drive instead. It’s better to reformat the
micro SD card or the USB flash drive with FAT32 file system before you copy audio files. When a micro SD card or
USB flash drive is inserted, the device will directly play the audio files from the inserted micro SD card or USB pen
flash drive.
If you directly load your audio files onto the internal memory of the device, please use the USB data cable to connect
the device to computer (Windows preferable). Once the connection is successful, the blue LED will keep flickering
and you’ll see a USB flash drive shown on computer. Delete the pre-loaded audio files at our factory, and copy your
own audio files to the memory. Please refer to the screenshot below.

6.3. Naming of Audio Files
The MP3 audio files must be named as ‘001.mp3’, ‘002.mp3’, ‘003.mp3’......‘999.mp3’. The audio files need to be
put in the root directory of the internal memory/micro SD card/USB flash drive. Folders can’t be used.
