2.4G Digital Wireless Audio Transceiver Module SOYO-WM24G02
which the LED is out, until the LED remains on. Stop pressing, and it will get into the
5-second-point-to-point ID pairing status where the LED flickers. If you keep on pressing the
button while the LED is flickering, it will keep on pairing, which is the function of pairing point
to mass, a function of one transmitter pairing a mass of several receivers.

2.1.3 Transmitter Module Using Methods
With unified channel and ID when produced, the Transmitter Moduleis ready to work as soon as it is interfaced in
accordance with Figure 1 and switched on.
For Mode A, switch is chosen through channel selection and 8 channels are available to avoid
interference .Receiver has to be adapted synchronously as transmitting channel is done when channel is
selected.
For Mode B, by adding function of ID pairing to it, interference can be resisted automatically. And it has 20
channels for you to choose. So to avoid getting sounds mixed up, having the function of ID pairing is suggested.
Paired ID is the real random address, whose coincidence rate is only 1/20,000,000, therefore it is nearly
impossible to have the coincidence
2.1.4 Channel Transform Methods of Transmitter
The module has an extremely good resistance to interference as a result of the 2.4G digital
wireless technology. It can be very effectively shielding the interference from cordless phones, cellular
phones, walkie-talkies and other wireless devices and ensures a hi-fi wireless audio. However, the
characteristics of the wireless products determine that the module can not avoid the interference with
