GENERAL INFORMATION GENERAL INFORMATION 2.1 The AMCOM III series of diver communication systems are full featured, hard wired, three diver communicators. The AMCOM III has independent microphone and earphone volume controls for each diver and the tender. All AMCOM III series have push-to-talk, and separate isolated inputs for each diver. The AMCOM III Model 2830A/24 is a portable three diver communication systems, delivering 20 watts "voice power", operating from either a 115/230 VAC, external 12 VDC power source, or an internal 12 VDC backup battery. The Model 2830A has the capability of 2-wire and/or Simulcom (4-wire) communication modes. 2- Wire and Simulcom (4-wire) modes can be used simultaneously. Simulcom is a communications system designed from the "ground-up" to take advantage of the current "state of the art" in semiconductor technology and provide superior diver hard wire communication. This portable diving radio has the ability to work with the Dynamic and Pre-Amplifier microphone in both 2-wire and 4-wire modes. This unique design has the ability to detect both pre-amp and dynamic diver microphones that are in use. This feature will automatically switch from a preamp mode to a dynamic mode and will adjust the specific diver gain (volume). The Model 2830A’s with 20 watts of power is the most powerful communicator on the market. The untouched volume and clarity allows the tender’s volume to be set at very high levels especially in noisy environments while the divers are at a comfortable listening level. 2
