INTRODUCTION
The Aegis
M-PA Select, Scan and System
portable radios are high-performance two-wa y radios
that provide clear voice, Aegis digital, and Aegis
private communications. The Select, Scan and System radios are also compatible with Voice Guard
communication systems. Personality programming
allows maximum integration flexibility into a public
service radio system.
The radio must be equipped with the encrypt/decrypt option before operation in Aegis private or V oice
Guard modes is possible. This option allows the r adio
to communicate using highly secure state-of-the-art
Aegis and Voice Guard encryption and decryption
techniques.
Operating controls include a rotatable control
knob, rotatable volume control, push-to-talk, emergency and monitor buttons. In addition, the Scan
model includes an eight-button keypad while the
System model includes a 16-button keypad. The
on/off power switch for the unit is located on the
removable battery pack.
status of the radio. This backlit displa y also pro vides
twelve status flags (Scan and System) or eight status
flags (Select) that indicate various operating conditions such as private communications enab led, 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 particular 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 switch 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 channel as displayed in the LCD. Sliding
the switch down will turn the radio off.
The 8-digit alphanumeric liquid crystal display
(LCD) on the front of the radio displays the operating

VOLUME CONTROL KNOB
The VOLUME CONTROL KNOB is a rotatable
control on the top of the radio used to adjust the
receiver’s audio level in the speaker. Rotating this
knob in a clockwise direction will increase the audio
level. Counter-clockwise rotation will decrease the
audio lev el. Minimum levels m ay be programmed into
the radio to prevent missed calls due to too low of a
volume setting.
CONTROL KNOB
Select Model
NEL/CG SELECTION 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.
Some radios may be programmed with this knob
disabled.
PTT BUTTON
Pressing the PTT BUTTON 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.
The rotatable 16-position CONTROL KNOB located on the top of the radio selects the operating
channel. 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.
Scan and System Models
The rotatable 16-position CONTROL KNOB located on the top of the radio is programmed to select
the operating channel, mode, or specific Channel
Guard encode/decode tones. See MODE/CHAN-

switched or f orced priv ate operation. In the switched
configuration, the PVT button is operational. In the
forced configuration, the button is not operational.
If the radio is programmed for forced private
operation and the selected channel is programmed
for private operation, "FRCD PVT" will be displayed
when PVT is pressed; private transmit mode cannot
be disabled. If the radio is programmed for forced
private operation and the selected channel is not
programmed for private operation, "PVT DIS" will
momentarily show in the display when PVT is
pressed; the radio will not change to private mode. If
the encrypt/decr ypt option is not installed, the PVT
button has no function.
