INTRODUCTION

This manual describes how to use
the M-PA EDACS S yst em Personal Ra-
dios. The M-PA EDACS Select, Scan,
and System Personal Radios are field
programmable microprocessor control­led portable radio designed for Digital
Trunkin g and Co nventional communica­tions.

6

All units on a conventional system
operate through the same radio re­peater. Trunked features (such as call
queuing and system scan) a re no t a v ai l­able in conventional mode.

TALK-AROUND OPERATION

Also referred to as “direct mode”,
talk-around provides a direct unit-to-unit
short range communications link. It is
intended to maintain communications

outside of the main system coverage
area.

TRUNKED OPERATION

Trunked Operation refers to the use
of a set of radio frequency channels by
multiple user groups. By using high
speed digital data your M-PA EDACS
radio goes t o an unused channel when
a call is initiated and will also only re­spond to calls in the same user group.
In this way conversation privacy be­tween user groups is assured.

SYSTEM (AREA) (Trunked operation
only)

The terms "system" and "areas" are
used interchangeably to refer to the
particular group of station repeaters
curren tly providing service to the radio.
Radios c an be preprogrammed to work
in different systems by changing the
CONTROL Knob position or by press­ing the STEP button (for SCAN and

SYSTEM models) depending on radio
programming. (e.g., different systems in
different cities).

GROUP OR SUBFLEET
(Trunked Operation Only)

A group of users share the same
preprogrammed group identification
number in the ir mobile and portable ra­dios. All units in the s ame gr oup will r e­ceive a di spatc h ca ll placed by any one
unit in the group.

FLEET (Trunked Operation Only)

A fleet of us ers consist s of multiple
groups (subfleets). Radios can be pre­programmed to make fleet calls to si­multaneously access multiple user
groups.

AGENCY (Trunked Operation Only)

An agen cy is composed of multiple
fleets. Units can be preprogrammed to

7

initiate agency calls to access multiple
fleets.

receive volume to the
desired listening level.

CONTROLS, DISPLAYS AND

CONNECTORS

CONTROLS
ON/OFF The Power ON/OFF

slide switch located on
the side of the battery
pack controls power
from the batter y pack to
the radio. Sliding the
switch up turns on the
radio and exposes the
yellow "ON" indicator.
This will also initiate the
personality self-test.
Sliding the switch down
turns the radio off.

MONITOR In the Trunked mode,

pressing the MONITOR
button enables non-su­pervisory users to clear
message trunked indi­vidual c alls, enter ed dig­its, and interconnect
calls. Supervisory units
may clear any call re­gardless of type, trans­mission or message
trunked. The MONITOR
button is also used to
clear any currently active
callback Status for both
supervisors and non-su­pervisors.

VOLUME The VOLUME Control

Knob, located o n the top
of the radio, adjusts the

In the Conventional
mode, the receiver may
be unsquelched by
pressing and holding the

MONITOR button. This

to the desired level.
When the button is re­leased, the radio mutes
unless a carrier and
channel guard (if en­abled) were detected in
the interim.

EMERGENCYThe EMERGENCY but-

(Trunked
mode only)

ton is used to initiate an
emergency call on the
programmed home
group or on the selected
group if no home group
is programmed.
