Operation GuideBefore updating audio files, you need to use a cross screwdriver to take it apart as pictures shown below.
Also remove the screw at the middle of the board, and get the board to the front side as below.
Note: For the users who just need the device to play a sound in a loop when power is applied, we don’t solder the four wires (black for GND, yellow for “Trigger Input”, brown for “Load+”and blue for “Load-”) on the circuit board. Instead, we just bridge the “GND”and “Trigger Input”through soldering.
Set a Trigger ModeThere are three trigger modes available tabled as below for users to choose. A trigger mode can be simply set through a config file that originally comes from a text file, and this config file needs to be placed together with the audio files on the memory.
Note: If there is no config file on the memory, the device always works with the first trigger mode “Play a sound in orderafter an activation (non-interruptible)”by default. Examples of Connections
1. One Switch Triggered Version (able to drive an external 12V DC light when a sound is playing)
Note: If you don’t need to connect with an external light, please cut off the brown and blue wires or tape the end of these two wires individually, just in case the two ends touch together and damage the internal circuit board!!
2. Play a Sound in a Loop When Power Is Applied (Loop upon Power-on)
Note: A config file is already saved in the memory for this option. Please don't delete it when you update audio file.
PS: It can be connected with a cigarette lighter socket plug connector. Dimensions
Note: If you think it is not convenient for you to tear apart the enclosure to update the sound files, you can send the sound file to us, and we'd like to pre-record it for you at our factory.
