INTRODUCTION

This manual describes how to use the Allegra Duplex Portable Radio. The Allegra Duplex is a synthesized, microprocessor-based, high performance duplex portable FM radio providing reliable two-way communications in Enhanced Digital Access Communications System (EDACS) trunking environments.

Duplex operation is provided in EDACS sys- tems while operating in the Telephone Interconnect Mode. At all other times, the radio

provides simplex communications, i.e. when placing group calls in the EDACS environments or when operating in the conventional mode.

In an EDACS trunked environment the user selects a communications system and group. In this mode, channel selection is transparent to the user and is controlled via digital communication with the system controller. This provides advanced programmable features and fast access to communication channels.

The exact operation of the radio depends on the operating mode, the radio's programming, and the particular radio system. Most features described in this manual may be enabled or disabled through programming. Consult the system administrator for the required features to be programmed into the radio.
