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. This radio comes in two models:
Interconnect only or Interconnect/Dispatch.
Duplex operation is provided in EDACS systems
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
radio model, 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.
Indicates Interconnect/Dispatch Model
Only operation or feature.
The portable radio has an antenna which can be
unfolded so that it points directly upwards and, when
not in use, can be folded down completely.
The 20-button keypad, an internal speaker and
a liquid crystal display (LCD) for radio status
information are located on the front of the radio.
