Instructions. MP3 wireless audio signal
Wireless horn” is a device for remotely sending warning messages, Heads, emergency and any other sound signals and phrases from the car, motorcycle, boats or being at some distance from them. It is possible to use it as an additional horn in transport. To send a signal, a compact remote control with 4 buttons is used, indicator, protective strip. The remote control also has a retractable antenna, it is necessary to increase the range of the system. Each button on the remote control corresponds to a piece of music, which can be downloaded to the device. For this purpose, a port with a USB connector for connecting to a computer is removed from the speaker..
When the module is connected to the computer, a new disk appears in the system, on which the directories “01” are located, “02”, “03”, “04”, “05”, “06” with files named 001.mp3, 002.Mp3, 003.Mp3, 004.Mp3, 005.mp3 in each directory. First 4 files correspond to buttons A,B,C,D on the remote, file 005.mp3 is the sound of an additional channel ( eg, for signaling when reversing or for use as an additional horn). To do this you need to switch the gray/white wire, coming out of the device to the common wire ( minus ) or to the plus supply 12V. The option selection can be changed using switch inside the horn. By default, the additional channel is set to be triggered by minus ( ie. when connected to the common negative wire ).
The choice of the working directory can be changed by simultaneously pressing 2 buttons on the remote control. In this case, short fragments of tracks from the selected set will be played in “silent mode”. The selected set is stored in the device's memory. There is 6 selections by pressing the AB buttons at the same time, AC, AD, BC, BD, CD. They correspond to the selection of the working directory "01" – “06 ”.
Structurally, the device consists of two parts – control panel with radio transmitter and speaker with receiver, control unit, decoder and amplifier.
The remote control is powered by a built-in 12V battery, type 23A. Batteries included for testing. In case of unstable operation of the device, We recommend installing higher quality batteries.
Power is supplied to the module via wires, emerging from the mouthpiece (as usual, Red +12V, black – weight). If you want to use the horn to signal from outside the car, подключившись к питанию до замка зажигания, то необходимо учитывать, that in standby mode the system consumes about 20 mA and with constant long-term use this can lead to battery discharge.
therefore, We strongly recommend connecting the device’s power supply to the electrical circuit after the ignition switch.
It is highly advisable to use an additional fuse in the power circuit.
