INTRODUCTION
The Aegis FDMR TS M-PA radio is a high quality m icro processor controlled synthesized portable two-way FM radio. The unit complements the Aegis FDMRTS trunked
system by providing a small, rugged, easy to operate and
easy to program portable radio for the UHF trunking environment. The radio also provides conventional communications in the UHF spectrum. M-PA operation is highlighted
by its programming versatility. This allows tailored operation of the portable radio to meet the needs of the radio system and the individual users. The Aegis FDMRTS M-PA
radio meets or exceeds all of th e APCO 16 portable radio
equipment requirements for digitally trunked and conventional commu nicati ons.
Aegis digital signals provide improved weak signal performance and impedance to unauthorized monitoring. Radios equipped with an encrypt/decrypt option offer very
secure communic ati ons when op erating in pr iva t e mode . MPA radios equipped with an encrypt/decrypt option can operate in two (2) diffe rent voic e modes. The voic e mo de s ar e:
Aegis digital and private. A radio not equipped with an encrypt/decrypt option can operate only in digital mode. A
clear voice (Analog) mode can also be programmed for test
purposes.
An Aegis FDMRTS M-PA radio’s voice mode is programmed on a per group basis. For example, if the radio is
equipped with an encrypt/de crypt option e ach trunked group
can be programmed for either private mode or Aegis digital
mode operation and the radio operates in the programmed
mode when the gro up is sele cte d.
Three (3) differe nt M- PA radio models are availa ble: 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 features 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 ope ration.
Scan and System model radios have an LCD similar to
the Select model radio. A keypa d is added to these radios (4button on Scan model, 16-button on System model) to provide 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 individual and telephone interconnec t call s. A Syste m mo de l 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 dialled
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 provide
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 wit h a maxi mu m of sixtee n (16 ) syste ms
with one group in eac h.
• Programmable Multiple Group Capability - The
radio can communicate with many groups within a
system. Scan and System model radios can be
programmed with a maxim um 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 selec t ed with the Control Knob.
• P rogrammable 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 multi-agency
communications.
• Remote Disable - If lost or stolen, the radio can be
remotely disabl ed by the System Ma nage r.
