INTRODUCTION
The Aegis

EDACS M-PA

Select model
portable radio is a high-performance two-way ra-
dio that provides clear voice, Aegis digital, and
Aegis private communications.The radio is also
compatible with Voice Guard®communication
systems. Personality programming allows maxi-
mum integration flexibility into EDACS and con-
ventional radio systems.
The radio must be equipped with the en-
crypt/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, ro-
tatable volume control, 16-button keypad, push-
to-talk, emergency and monitor buttons. The
on/off power switch for the unit is located on the
removable battery pack.
The8-digitalphanumericliquidcrystaldisplay
(LCD) on the front of the radio displays the oper-
ating status of the radio. This backlit display also
has sixteen status flags that indicate various op-
erating conditions such as private communica-
tions enabled, transmitter on, scanning, or emer-
gency mode enabled.
The exact operation of your radio will vary
depending upon the mode of operation, the ra-
dio’s programming, and the particular radio sys-
tem. Consult your radio system’s representative
for particular features that are programmed into
your radio.
CONTROLS
ON/OFF SWITCH
The ON/OFF SWITCH is located on the bat-
terypack. Slidingthisswitchupwillsupplypower
totheradiofromthebatterypack. Anaudibleclick
will be heard and the "ON" indicator will be ex-
posed. Whentheradioisturnedon,itwillperform
a power-up self test and then resume operation
ontheprevious operatingsystem,grouporchan-
nel as displayed in the LCD. Sliding the switch
down will turn the radio off.
VOLUME CONTROL KNOB
TheVOLUMECONTROLKNOBisarotatable
control on the top of the radio used to adjust the
5

receiver’saudiolevelinthespeaker. Rotatingthis
knob in a clockwise direction will increase the
audio level. Counter-clockwise rotation will de-
crease the audio level. Minimum levels may be
programmedintotheradiotopreventmissedcalls
due to too low of a volume setting.
CONTROL KNOB
The rotatable 16-position CONTROL KNOB
located on the top of the radio may be pro-
grammed to select trunked groups and conven-
tionalchannelsoritmaybeprogrammedtoselect
systems. SeeSYSTEM/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 normally factory installed
for fifteen (15) positions.
PTT BUTTON
PressingthePTTBUTTONontheside ofthe
radio will enable the radio’s transmitter. The "TX"
statusflaginthedisplaywillturnonwhentheradio
is transmitting. Releasing the PTT BUTTON will
return operation to receive mode.
Whenoperatinginatrunkedsystem,theradio
may be programmed to automatically transmit
(withouttheoperatorpressing thePTTBUTTON)
tomaintaincommunicationwiththesitecontroller.
The "TX" statusflag will turn on when theradio is
transmitting.
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
groupcallmode. Theradiowillnotrespondonan
individual basis, but will then transmit groupcalls
whenthePTTBUTTONispressed. Theradiowill
also automatically return to the group call mode
after the programmed call-back time-out period
expires.
Pressing the MONITOR BUTTON will also
clear any digits entered from the numeric keypad
andreturntheradiototheselectedgroupdisplay.
In addition, this button is used to toggle be-
tween group and regroup settings if the Dynamic
Regrouping mode (with deselect capability) has
been enabled by the site controller.

Conventional Mode
When the radio is operating in conventional
mode the MONITOR BUTTON is used to un-
squelch the receiver. If programmed for the se-
lected channel, it will also toggle Channel Guard
(CG) and/or Type 99 (T99) signaling on and off.
Momentarily pressing the MONITOR BUT-
TON will unsquelch the receiver. If programmed,
pressing and holding the button for at least one
(1)secondwilltoggleCGand/orT99signalingon
oroff. AfteraT99callhasbeenreceived,pressing
theMONITORBUTTONwillresettheradioforthe
next call. Note: Selecting another channel will
turnCGandT99signalingbackonifprogrammed
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
willinitiateanemergencycallwithvoiceoperation
on the programmed home group. If no home
group is programmed into the radio, voice opera-
tion will be on the selected group.
In conventional mode, initiating an emer-
gency call by pressing the EMERGENCY BUT-
TON will cause the radio to transmit GE-STAR
signaling on the programmed emergency chan-
nel. If no emergency channel is programmed,
GE-STAR will be transmitted on the selected
channel.
INDICATORS
The radio’s liquid crystal display (LCD) lo-
cated on the front panel has eight (8) alphanu-
meric characters and sixteen (16) status flags.
This display provides indications of the current
operating system, group or channel and it dis-
playsvariousothermessagessuchasspecialcall
ID names or numbers, and telephone intercon-
nect numbers.
LCDbacklightingwillturnonforashortperiod
anytime an active button is pressed or the CON-
TROL KNOB is rotated. Backlighting may be
programmed to remain off at all times.
Thesixteen(16)statusflagslocatedalongthe
top and bottom of the display indicate operating
modes and conditions as follows:

emergency call has been initiated by
the user. Flashing indicates an emer-
gency call has been received.

UNIVERSAL DEVICE CONNECTOR
The Universal Device Connector (UDC) is
locatedonthesideoftheradiojustabovethePTT
and MONITOR BUTTONS. This connector pro-
vides connections for the external accessories
such as a headset, a speaker-mike, or an emer-
gency lanyard. When the radio is locked in a
vehicularcharger/repeater,theUDCprovidesthe
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.
ALERT TONES
The radio sounds five (5) basic alert tones or
"beeps" to indicate various operating conditions.
Alert tones may be programmed to remain off at
all times.
•500 Hz Tone –trunked failure tone -
sounds when a trunked
failure has occurred (call
denied, failed confirma-
tion).

OPERATION
POWER-UP
Afterthebatterypackandantennahavebeen
installed, turn the radio on by sliding theON/OFF
SWITCH on the battery pack up. After the radio
has completed a power-up self-test, it will begin
operationonthelastoperating stateasdisplayed
intheLCD. Ifprogrammedon,thepower-upalert
tone (beep) will be heard.
If the radio was previously operating in a
trunkingsystemandcommunicationwiththissys-
tem’s control channel cannot be established, the
"NC"statusflagwillturnon. Thismayoccurif,for
example, the radio is out of range of the previous
trunking site. It may be necessary move to an-
other location, select another trunking system, or
a conventional channel.
VOICE MODES
Each system (trunked or conventional) in the
radio is programmed for either Aegis or Voice
Guard communications.Aegis programmed sys-
tems have three (3) different voice modes:clear,
digitalandprivate.VoiceGuardsystemshavetwo
(2) voice modes: clear and private. The voice
modes are programmed on a per-group basis
withineachtrunkedsystemandonaper-channel
basis within each conventional system. A radio
mustbeequippedwiththeencrypt/decryptoption
before it will operate in Aegis private or Voice
Guard modes.
Clear Mode

identicalvoicemodesinwhichtheradiotransmits
and receives only clear (analog) voice signals.
These analog signals are non-digitized and non-
encrypted.Clearmodetransmissionscanbeeas-
ily monitored by unauthorized persons. Groups
and channels programmed for clear operation
cannot transmit or receive Aegis digital or private
messages.
Aegis Digital Mode

and receive digitized voice signals. Aegis digital
signals provide improved weak signal perform-
ance and they cannot be easily monitored with a
