1 Introduction

The model C-2002 is a full-featured Two-Line, multi-format, and self-contained desktop radio control console. Its sleek and modern look will compliment any surroundings.

The C-2002 is a Digital Signal Processor (DSP) based design, allowing easy field programmability using the DTMF and soft keypads on the front of the console. Unlike other manufacturers’ equipment, no additional software is required to program the C-2002 console. Modifications and enhancements can generally be made via a software change only. If the user determines they require a special feature enhancement, please contact the Vega Sales Department for cost and feasibility.

Initial Line level adjustments are made via potentiometers allowing for ease of installation. Should additional adjustments be required, they can be made in the programming mode. AGC on receive and microphone audio paths help stabilize line level adjustments.

The C-2002’s modular design offers control of one base station, along with selection of 99 frequencies. The line interface offers crossmute capability and squelch control feature eliminating the unwanted noise that is generally associated when monitoring a line.

The C-2002 will accommodate a desk microphone along with a handset (or headset) as indicated on the side of the C-2002 console. In addition to the external microphone options, a built in panel microphone is available by pressing the PTT on the front of the panel. When a PTT occurs from any of the three microphones, the others will mute so as not to pick-up unnecessary ambient noise during transmission. When the handset is enabled and taken off hook the receive audio is transferred to the earpiece.

The console is normally used in conjunction with a matching Vega 223 Series (or equivalent) tone-remote panel located at the base station. The console is compatible with Motorola, MA/ComNet Ericsson/GE, and other tone- remote control systems employing the industry-standard sequential tone-control format.

The console is connected to the mating panels by means of shielded voice-grade or better leased or private lines (including microwave circuits). Metallic or DC continuity is not required.
