Digi-Wave™ 400 Series Digital Transceiver and Receiver USER MANUAL PRELIMINARY MANUAL System Overview The Digi-Wave communication system allows users to listen and talk to one another wirelessly in a variety of scenarios. A Digi-Wave system consists of at least one transceiver (DLT 400) and various combinations of transceivers and receivers (DLR 400). The DLT 400 is a two-way transceiver, meaning that it can transmit and receive audio simultaneously. The DLR 400 is a receiver only. Users of DLR 400 receivers can only hear what is being broadcast by DLT(s); they cannot create any audio. There are two models of DLR: the DLR 400 ALK and the DLT 400 RCH.
