INTRODUCTION AND SPECIFICATIONS
INTRODUCTION
1.1
The 2810E-2001 is the newest member of the Amron International AMCOM series of
chamber communicators. The 2810E-2001 is a full featured, panel mounted, single
chamber communicator that uses state-of-the-art electronics and introduces several new
features. The first new feature is a digital audio power amplifier which significantly reduces
the current draw, nearly doubling the battery life. The 2810E-2001 uses a new audio filtering
network for improved sound clarity and communications. An auxiliary audio input allows
chamber occupants to listen to audio from a MP3 player while remaining in constant
communication with the operator. Please note that this feature is only available for a
chamber operating in the 4-Wire mode. These new features allow the AMCOM I 2810E-2001
to remain the most advanced single chamber communicator on the market. To enjoy all the
features, it is important that the operator read and understand the entire manual including all
warnings.
The 2810E-2001 can operate in 2-Wire or Full Duplex (4-Wire) communication modes.
There is a single volume control for the up-link (Operator) and another volume control for the
down-link (Chamber). Designed for a long and dependable service life, the 2810E-2001 has
a stainless steel front panel with a waterproof speaker and heavy-duty switches with
waterproof seals. The 2810E-2001 is enclosed in a rugged, aluminum housing with power
and chamber connections located on the back panel.
