INTRODUCTION
The Aegis
EDACS M-PA Select model
portable radio is a high-performance two-way radio that provides clear voice, Aegis digital, and
Aegis private communications. The radio is also
compatible with Voice Guard
®
communication
systems. Personality programming allows maximum integration flexibility into EDACS and conventional radio systems.
erating conditions such as private communications enabled, transmitter on, scanning, or emergency mode enabled.
The exact operation of your radio will vary
depending upon the mode of operation, the radio’s programming, and the par ticular radio system. Consult your radio system’s representative
for particular features that are programmed into
your radio.
The radio must be equipped with the encrypt/decrypt option before operation in Aegis
private or Voice Guard modes is possible. This
option allows the radio to communicate using
highly secure state-of-the-art Aegis and Voice
Guard encryption and decryption techniques.
Operating controls on the radio include a
rotatable system/group/channel control knob, rotatable volume control, 16-button keypad, pushto-talk, emergency and monitor buttons. The
on/off power switch for the unit is located on the
removable battery pack.
The 8-digit alphanumeric liquid crystal display
(LCD) on the front of the radio displays the operating status of the radio. This backlit display also
has sixteen status flags that indicate various op-
CONTROLS
ON/OFF SWITCH
The ON/OFF SWITCH is located on the battery pack. Sliding this s witch up will supply power
to the radio from the battery pack. An audible click
will be heard and the "ON" indicator will be exposed. When the radio is turned on, it will perform
a power-up self test and then resume operation
on the previous operating system, group or channel as displayed in the LCD. Sliding the switch
down will turn the radio off.
VOLUME CONTROL KNOB
The VOLUME CONTROL KNOB is a rotatable
control on the top of the radio used to adjust the
5
receiver’ s audio le v el in the speaker . Rotating this
knob in a clockwise direction will increase the
audio level. Counter-clockwise rotation will decrease the audio level. Minimum levels may be
programmed into the radio to pre vent missed calls
due to too low of a volume setting.
When operating in a trunked system, the radio
may be programmed to automatically transmit
(without the operator pressing the PTT BUTTON)
to maintain communication with the site contr oller.
The "TX" status flag will turn on when the radio is
transmitting.
CONTROL KNOB
The rotatable 16-position CONTROL KNOB
located on the top of the radio may be programmed to select trunked groups and conventional channels or it may be progr ammed to select
systems. See SYSTEM/GROUP/CHANNEL SE-
LECTION for details.
A stop plate may be installed under the knob
to limit the maximum number of positions to less
than sixteen (16). It is nor mally factory installed
for fifteen (15) positions.
PTT BUTTON
Pressing the PTT BUTT ON on the side of the
radio will enable the radio’s transmitter. The "TX"
status flag in the display will turn on when the radio
is transmitting. Releasing the PTT BUTTON will
return operation to receive mode.
MONITOR BUTTON
Trunked Mode
When operating in trunked mode, pressing
the MONITOR BUTTON after an individual call
has been received will return the radio to the
group call mode. The r adio will not respond on an
individual basis, but will then transmit group calls
when the PTT BUTT ON is pressed. The radio will
also automatically return to the group call mode
after the programmed call-back time-out period
expi res.
Pressing the MONITOR BUTTON will also
clear any digits entered from the numeric keypad
and return the radio to the selected group displa y.
In addition, this button is used to toggle between group and regroup settings if the Dynamic
Regrouping mode (with deselect capability) has
been enabled by the site controller.
6
Conventional Mode
When the radio is operating in conventional
mode the MONITOR BUTTON is used to unsquelch the receiver. If programmed for the selected channel, it will also toggle Channel Guard
(CG) and/or Type 99 (T99) signaling on and off.
In conventional mode, initiating an emergency call by pressing the EMERGENCY BUTTON will cause the radio to transmit GE-STAR
signaling on the programmed emergency channel. If no emergency channel is programmed,
GE-STAR will be transmitted on the selected
channel.
Momentarily pressing the MONITOR BUTTON will unsquelch the receiver. If programmed,
pressing and holding the button for at least one
(1) second will toggle CG and/or T 99 signaling on
or off. After a T99 call has been received, pr essing
the MONITOR BUTT ON will reset the radio f or the
next call. Note: Selecting another channel will
turn CG and T99 signaling back on if programmed
for the channel.
EMERGENCY BUTTON
When operating in trunked mode, pressing
and holding the red EMERGENCY BUTTON on
top of the radio for approximately one (1) second
will initiate an emergency call with voice operation
on the programmed home group. If no home
group is programmed into the radio, voice operation will be on the selected group.
INDICATORS
The radio’s liquid crystal display (LCD) located on the front panel has eight (8) alphanumeric characters and sixteen (16) status flags.
This display provides indications of the current
operating system, group or channel and it displays v arious other messages such as special call
ID names or numbers, and telephone interconnect numbers.
LCD backlighting will turn on f or a short period
anytime an active button is pressed or the CONTROL KNOB is rotated. Backlighting may be
programmed to remain off at all times.
The sixteen (16) status flags located along the
top and bottom of the display indicate operating
modes and conditions as follows:

UNIVERSAL DEVICE CONNECTOR
The Universal Device Connector (UDC) is
located on the side of the radio just above the PTT
and MONITOR BUTTONS. This connector provides connections for the external accessories
such as a headset, a speaker-mike, or an emergency lanyard. When the radio is locked in a
vehicular charger/repeater, the UDC provides the
audio and control connections between the radio
and the vehicular charger/repeater. The UDC is
also used by the maintenance personnel when
the radio is programmed.

OPERATION
POWER-UP
After the battery pack and antenna ha ve been
installed, turn the radio on by sliding the ON/OFF
SWITCH on the battery pack up. After the radio
has completed a power-up self-test, it will begin
operation on the last operating state as displayed
in the LCD . If programmed on, the power -up alert
tone (beep) will be heard.
If the radio was previously operating in a
trunking system and communication with this system’s control channel cannot be established, the
"NC" status flag will turn on. This ma y occur if, for
example , the radio is out of range of the previous
trunking site. It may be necessar y move to another location, select another trunking system, or
a conventional channel.
Guard communications. Aegis programmed systems have three (3) different voice modes: clear,
digital and private. Voice Guard systems hav e two
(2) voice modes: clear and private. The voice
modes are programmed on a per-group basis
within each trunked system and on a per-channel
basis within each conventional system. A radio
must be equipped with the encrypt/decrypt option
before it will operate in Aegis private or Voice
Guard modes.
Clear Mode
Aegis clear and Voice Guard clear modes are
identical voice modes in which the radio tr ansmits
and receives only clear (analog) voice signals.
These analog signals are non-digitized and nonencrypted. Clear m ode transmissions can be easily monitored by unauthorized persons. Groups
and channels programmed for clear operation
cannot transmit or receive Aegis digital or private
messages.
Aegis Digital Mode
VOICE MODES
Each system (trunked or conventional) in the
radio is programmed for either Aegis or Voice

Aegis digital mode allows the radio to transmit
and receive digitized voice signals. Aegis digital
signals provide improved weak signal performance and they cannot be easily monitored with a
