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 resume operating
on the previous group or channel. 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 receiver’s volume level
in the speaker. Rotating this knob in a
clockwise direction will increase the vol-
ume and counter-clockwise rotation will
decrease the volume. Minimum volume
levels can be programmed into the radio to
prevent missed calls when the knob is
rotated fully counter-clockwise.

INTRODUCTION
The EDACSM-PASelect, Scan
and System model radios are high-quality
microprocessor-controlled synthesized
two-way FM portable radios. These full-
featured radios are designed for operation
inEDACS(EnhancedDigitalAccessCom-
munications System) trunking systems
and conventional radio systems. M-PAop-
eration is highlighted by the radio’s pro-
gramming versatility. This permits custom
operation of each radio to meet the needs
of the radio system and the individual us-
ers.
This manual describes operating pro-
cedures for the three (3) different radio
models.
The M-PA Select model radio is the
basic version of the radio that can be pro-
grammed with up to sixteen (16) inde-
pendent trunked groups and/or
conventional radio channels. This unit fea-
tures an eight-digit alphanumeric liquid
crystal display (LCD) and a 16-position
knob for group/channel selection. The dis-
play also has status flags that indicate
various operating modes and it is backlit
for nighttime and low-level ambient light
operation.
Scan and System model radios have
an LCD similar to the Select model radio.
These radios have front panel keypads
that provide additional operating features
not available on the Select model radio.
The Scan model radio has a 4-button key-
pad and the System model radio has a
16-button keypad. Additional features in-
clude expanded system and group/chan-
nel selection capability, trunked group and
conventional channel scan capability,
trunkedmodeindividualcallcapability,and
telephone interconnect call capability. The
numeric keypad on the System model ra-
dio also allows storage of ten (10) opera-
tor-entered telephone numbers and ten
(10) operator-entered radio ID numbers.
These numbers can be recalled at will and
initiated. Manually dialed telephone inter-
connect with overdial capability and con-
ventional mode DTMF dialing is also
provided by the Systemmodel’s 16-button
keypad.

The rotatable 16-position CONTROL
KNOB located on the top of the radio pro-
vides system, group or channel selection
accordingtohowtheradioisprogrammed.
A stop plate may be installed under the
knob to limit the maximum number of po-
sitions to less than sixteen (16). It is nor-
mally factory installed for fifteen (15)
positions.
On the Select model radio, the CON-
TROL KNOB selects any one of trunked
systems and groupsor conventionalchan-
nels programmed into the radio.
On Scan and System model radios,
the CONTROL KNOB is used in combina-
tion with the keypad to select a specific
trunked system and group or a conven-
tional channel. The selection method is
determined by the radio’s programming.
See the section entitled "SYS-
TEM/GROUP/CHANNEL SELECTION" in
the "OPERATION" section of this manual
for details.
PTT BUTTON
Pressing the PTT BUTTON on the
side of the radio turns on the radio‘s trans-
mitter. 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 on a trunked system,
the radio may be programmed to automat-
ically transmit (without the operator press-
ing the PTT BUTTON) to maintain
communicationwiththesitecontroller.The
"TX" status flag in the display will turn on
when the radio is transmitting.
MONITOR BUTTON
Trunked Mode
The exact operation of a particular ra-
dio will vary depending upon its mode of
operation, its programming, and the par-
ticular radio system. Consult a radio sys-
tem’s representative for particular features
that are programmed into the radio.
The radio operates in trunked mode
when a trunked system is selected and it
operates in conventional mode when a
conventional system is selected.

When operating on a trunked system
in special call mode, pressing the MONI-
TOR BUTTON after an individual call has
been received will return the radio to the
groupcallmode.Inthiscondition,theradio
will not respond on an individual basis but
it will then transmit group calls upon sub-
sequent activations of the PTT BUTTON.
The radio will also automatically return to
the group call mode after the programmed
individual call-back time-out period ex-
pires.
This button is also used to toggle be-
tween group and regroup settings if the
Dynamic Regrouping mode (with deselect
capability) has been activated by the site
controller.
On the System model radio, pressing
the MONITOR BUTTON will clear all digits
entered from the numeric keypad and re-
turntheradiototheselectedgroupdisplay.
Conventional Mode
Whentheradioisoperatinginconven-
tional mode (on a conventional channel),
the MONITOR BUTTON is used to tempo-
rarily unsquelch the receiver so channel
traffic can be monitored. Momentarily
pressing it will unsquelch the receiver.
If the selected channel has Channel
Guard (CG) and/or Type 99 (T99) coded-
squelch tone decode feature programmed
for the selected channel, this button is can
also be used to enable and disable the
programmed feature. Repeated activa-
tions will toggle CG and/or T99 between
the enabled (on) and disabled (off) states.
To toggle the programmed feature, press
and hold the MONITOR BUTTON for at
least two (2) seconds until the appropriate
status flag in the display toggles.
The MONITOR BUTTON is also used
to reset the radio after a Type 99 (T99)
selective call has been successfully re-
ceived. If the radio is operating in a Type
99 mode, momentarily press the MONI-
TOR BUTTON to reset the radio after a
T99 call is successfully received.
EMERGENCY BUTTON
When the radio is operating in trunked
mode, pressing and holding the red
EMERGENCY BUTTON on top of the ra-
dio for approximately one (1) second will
8

initiate an emergency call on the pro-
grammed home group. If no home group
is programmed into the radio the emer-
gency call will be transmitted on the se-
lected group.
In conventional mode, initiating an
emergency call by pressing the EMER-
GENCY BUTTON will cause the radio to
transmit GE-STAR emergency signaling
on the programmed emergency channel.
If no emergency channel is programmed,
GE-STAR emergency signaling will be
transmitted on the selected channel.
STEP BUTTON
(Scan And System Models Only)
The STEP button located on the key-
pad can be programmed to select trunked
groupsandconventionalchannelsoritcan
beprogrammedtoselectsystems.Seethe
section entitled "SYSTEM/GROUP/
CHANNEL SELECTION" for details.
STEPis also used to scroll through the
programmed special call table when the
special call mode is enabled.
SCAN BUTTON
(Scan And System Models Only)
Pressing the SCAN button on the key-
pad will toggle scan operation on and off
When the radio is scanning, the "SCN"
status flag in the display willturn on and all
groups/channels on the scan list in the
current system will be scanned.
SPC BUTTON
(Scan And System Models Only)
Pressing SPC will switch operation
from the group select mode to the special
call mode. The last selected special call
will be displayed.
While in special call mode, the next
programmed special call can be selected
by pressing STEP. Pressing 2nd then
STEPwill select the previous programmed
special call. The caller’s ID of the last
received individual call and the last re-
ceivedgroupcallontheselectedgroupare
a selectable using this method. See "Spe-
cial Calls" for details.

2nd BUTTON (Scan And System
ModeIs Only)
On an M-PAScan model radio the two
(2) centerbuttons (SCAN and SPC)on the
keypad are dual-function buttons. The
second or shifted functions are accessed
by first pressing the blue 2nd button. The
SCAN button’s second function is scan
add/delete for scan list updating. The sec-
ond function for the SPC button is the
keypad lock feature.
On an M-PA System model radio, six
(6) of the buttons on the keypad are dual-
function buttons. Press and release the
blue 2nd function button to shift keypad
selection to the scan add/delete (SCAN
button), the keypad lock feature (SPC but-
ton), STO, RCL, CLR, or STS buttons.
ADD/DELETE BUTTON
(Scan And System Models Only)
When in trunked mode, pressing and
releasing 2nd and then pressing A/D
(shifted SCAN button) will toggle the se-
lectedgroupon andoff thescan list.When Figure 6 - System Model Keypad
