INTRODUCTION

The Aegis



ED AC S M-PA System 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.

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 oper-

ating status of the radio. This backlit display also
has sixteen status flags that indicate various op­erating 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.

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

PTT BUTTON

The VOLUME CONTROL KNOB is a rotatable
control on the top of the radio used to adjust the
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.

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.

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.

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.

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.

6

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.

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.

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.

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.

STEP BUTTON

The STEP button located on the keypad may
be programmed to select trunked groups and
conventional channels or it may be programmed
to select systems. See SYSTEM/GROUP/CHAN-
NEL SELECTION for details.

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 Modes

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.
