DESCRIPTION
This manual contains essential information needed to main-
®
tain the Ericsson ALLEGRA EDACS
800 MHz Duplex Port-
able radio. Included in this manual is a brief description of the
radio, troubleshooting and alignment information, radio disas-
sembly and reassembly procedures, battery replacement and
disposal procedures, and circuit descriptions.
The ALLEGRA Duplex Portable radio is synthesized, mi-
croprocessor based, high performance duplex portable FM ra-
dio. Operation in the 800 MHz frequency range this radio
provides reliable two-way radio communications in EDACS
environments. The ALLEGRA EDACS radio is available in two
models: Interconnect only or Interconnect/Dispatch. A wide
variety of options and accessories are available.
Duplex operation is provided in EDACS systems while
operation in the Telephone Interconnect mode. At all other
times, the radio operates in the half-duplex mode, i.e. when
placing group calls in the EDACS environments.
Advanced state- of- the -art technology is used in the design
and manufacture of this synthesized radio to provide the most
in flexibility, capability, and adaptability to various system
configurations. This flexibility allows the user to have the
operation of his radio customized or tailored (by programming)
to satisfy his needs by activating the desired features. The
ALLEGRA is small, compact, lightweight, yet ruggedly con-
structed to provide reliable service.

PROGRAMMABLE FEATURES
The Allegra is PC programmable, allowing it to be custom-
ized or upgraded quickly and easily. All programmable func-
tions are controlled by the microcomputer and are field pro-
grammable through a compatible DOS based PC. The micro-
computer reads specific information from the EPROM. Refer
to the EDACS Software Programming manual for programming
details.
In addition to the 50 number memory, the ALLEGRA duplex
portable radio allows several time-out options to accommodate
user needs.
User programmable features include:
•
50 number memory
•
Carrier Control Timer - A single value can be se-
lected that applies to all trunked operation.
•
Voice Scan Lockout Timer - Provides a time limit
that disables group scanning following initiation of a
voice call.
•
Special Call Time Out - Drops the radio out of spe-
cial call mode after a specified period of operator in-
activity.
•
Individual/Interconnect Call time-out - A time-out
that drops the radio out of an individual/interconnect
call after a specified period of time.
OTHER PROGRAMMABLE FEATURES
•
Flex Keys - Any one of these three keys (A, B, or C)
can be programmed to function as the emergency
button.
•
Automatic Login - Supported for EDACS Systems
•
Wide Area Scan - Supports wide area roaming.
When scanning, there is a programmable time inter-
val that determines when the radio starts scanning
the next site.
•
Supervisory Mode - Allows the radio to handle all
normal supervisory functions.
•
Programmable Audio/Display - This programmable
option handles display and audio during emergency
situations. The display can be programmed to hold
the display unchanged until PTT is pressed or the
emergency is cleared. The audio option similarly ,
