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.
