INTRODUCTION

The EDACS M-PA radio is a high quality microproces-

sor-controlled synthesized portable two-way FM radio. The
unit complements the EDACS trunked system by providing
a small, rugged, easy to operate and easy to program port-
able radio for the 800 MHz trunking environment. The radio
also provides conventional communications in the 800 MHz
spectrum. M-PA operation is highlighted by its program-
ming versatility. This allows tailored operation of the port-
able radio to meet the needs of the radio system and the
individual users.

 The EDACS M-PA radio meets or exceeds all of the

APCO 16 portable radio equipment requirements for digi-
tally trunked and conventional communications. NPSAPC
capability is also built-in since the radio will operate in the 6
MHz band of narrow channels in the 800 MHz spectrum.

 Three (3) different M-PA radio models are available:

Select, Scan and System.

 The M-PA Select model radio is the basic version that

can be programmed with up to sixteen (16) independent
trunked groups and/or conventional channels. This unit fea-
tures an eight-digit alphanumeric liquid crystal display
(LCD) and a 16-position knob for group/channel selection.
The display is backlit for nighttime and low-level ambient
light operation.

 Scan and System model radios have an LCD similar to

the Select model radio. A keypad is added to these radios (4-
button on Scan model, 16-button on System model) to pro-
vide additional features not available on the Select model
radio. These radios can be programmed with up to fifty (50)
systems with sixteen (16) groups in each, or sixteen (16)
systems with fifty (50) groups in each. In addition, up to
forty-eight (48) conventional channels and ninety-nine (99)
special calls can be programmed. Special calls include indi-
vidual and telephone interconnect calls. A System model ra-
dio also allows storage of ten (10) operator-entered
telephone numbers and ten (10) radio ID numbers. These
numbers can be recalled at will and initiated. Manually di-
alled telephone interconnect calls and conventional mode
DTMF dialing is also provided by the System model’s 16-
button keypad. Both the Scan and System model radios pro-
vide scan capability.

TRUNKED FEATURES

Programmable Multiple System Capability - The
radio can operate on different trunked sites or on
different systems on the same site. Scan and System
model radios can be programmed with a maximum of

fifty (50) systems with a maximum of sixteen (16)
groups in each system. A Select model radio can be
programmed with a maximum of sixteen (16) systems
with one group in each.

Programmable Multiple Group Capability - The
radio can communicate with many groups within a
system. Scan and System model radios can be
programmed with a maximum of fifty (50) groups per
system. If the Control Knob is programmed for group
selection, up to sixteen (16) groups can be selected
and system selection (50 maximum) is accomplished
with the STEP button on the keypad. If the Control
Knob is programmed for system selection, up to
sixteen (16) systems can be selected and then up to
fifty (50) groups can be selected via the STEP button.
In a Select model radio, a maximum of sixteen (16)
groups (from one or more systems) can be
programmed and selected with the Control Knob.

Programmable Group Call Capability - The radio
can simultaneously call all units within a group.

Special Call Mode - Scan and System model radios
can initiate special calls. These calls include
individual and telephone interconnect calls. Up to
ninety-nine (99) special calls can be programmed into
the radio. Special calls cannot be programmed into a
Select model radio; therefore, these radios cannot
initiate special calls.

Remote Dynamic Regrouping Capability - The
dispatch center can regroup radios for multiagency
communications.

Remote Disable - If lost or stolen, the radio can be
remotely disabled by the System Manager.

Wide Area System Scan Capability - This feature,
for multi-site applications, allows the radio to
automatically roam from one system to another when
the current control channel is lost or on a priority scan
timer basis. In the event of a loss of the current
system’s control channel, the radio can be
programmed to automatically scan for control
channels of up to six other systems. If a new control
channel is found, the radio will switch to the new
system and sound an alert tone. Group selection may
change upon switching to the new system. The radio
can also be programmed for priority wide area system
scan. A priority system can be assigned to each
system programmed into the radio. Radios
programmed in this manner will scan for the priority
trunked system’s control channel once every one, two,
three or four minutes (programmable). This priority
scan timer is reset each time the PTT button is
pressed.
