OPERATION GUIDE
GENERAL DESCRIPTION
The WA-TX-03S / WA-RX-03S are 15ch multichannel audio modules that operate in
the European harmonized 863 - 865 MHz band. In addition to offering a frequency
range sufficient for voice transmission, the compander noise reduction system has a
wide dynamic range, enabling transmission of clear audio signals.
As embedded devices, they include nearly all the parts necessary for audio
transmission in a small shielding case, making it possible to develop audio
transmission equipment in a short time.
