The GSM DC™ underwater transceiver unit incorporates the latest innovations in underwater ultrasonic 2-way radio communication. The unit features a digital driver for vocal message equalization, an automatic system for activating transmission (DAT™), and a double transceiver channel. The standard frequency (channel 1) is the same for all Neptune System units, so it is possible to communicate with any other GSM, GSM DC™, GSM G-Power, GSM G-Power SL, GSM CUBE3, M101A receive units, M105 Digital surface units, and all discontinued units.Underwater communication is accomplished through ultrasound and can be used in two unique modes, manual transmission mode and automatic transmission mode. To start communication in manual PTT (Push to Talk) mode, press and hold the “A” button (see picture) to transmit and release the button to receive. The “B” button activates and de-activates the automatic transmission mode, DAT™ (see later). The GSM DC™ automatically begins receiving capabilities upon contact with the water. The GSM DC™ is a dual channel (DC) unit, which means it is equipped with two transceiver channels. By pressing buttons “A” and “B”, it is possible to change the frequency channel. Any time the channel is changed, a recorded message informs the diver of which channel has been activated (channel 1 or channel 2). The two channels allow different diving groups to operate in the same area with limited interference and confusion. The GSM DC™ sound quality depends upon both the D-Mic microphone, a special dynamic microphone with high acoustic qualities, and the microprocessor (DSP), which takes the digitized vocal message and filters out unwanted noise such as exhaust, air bubbles, or mask vibrations.
