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

in EDACS (Enhanced Digital Access Com-

munications System) trunking systems

and conventional radio systems. M-PA op-

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,

trunked mode individual call capability, 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 System model’s 16-button

keypad.

Figure 3 - Scan Model

Figure 4 - System Model

The rotatable 16-position CONTROL

KNOB located on the top of the radio pro-

vides system, group or channel selection

according to how the radio is programmed.

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 groups or conventional chan-

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

communication with the site controller. 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

group call mode. In this condition, the radio

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-

turn the radio to the selected group display.

Conventional Mode

When the radio is operating in conven-

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

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

groups and conventional channels or it can

be programmed to select systems. See the

section entitled "SYSTEM/GROUP/

sliding the ON/OFF SWITCH on the bat-

tery pack up. After the radio has completed

a power-up self-test, it will begin opera-

tion on the last operating state as dis-

played 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 may occur if, for example, the

radio is out of range of the previous trunk-

ing site. It may be necessary to move to

another location, select another trunking

system, or a conventional channel.

SYSTEM/GROUP/CHANNEL SELEC-

TION

TRUNKED MODE OPERATION

Digital trunking provides fast commu-

nication access. In this mode the operator

selects a communication system and

group and the communication channel is

allocated through digital signalling with the

site.

Receiving A Message

1. Slide the ON/OFF SWITCH on

the battery pack up to the on

position. The radio will initiate

and complete the power-up self-

test then the system’s name and

"NC" status flag will be displayed

until a control channel is located.

When the control channel is lo-

cated, the "NC" status flag dis-

appears and the group name is

displayed.

2. Adjust the VOLUME CONTROL

to an approximate mid-range po-

sition.

3. Select the desired system and

group. See the section entitled

"SYSTEM/GROUP/CHANNEL

SELECTION" operating proce-

dures for details. The dis-

play indicates the selected

group.

4. The radio is now ready to receive

messages.

5. GROUP CALL - When a group

call is received, the radio un-

squelches on the assigned

channel and the "BSY" status

flag turns on. The group name or

the originator’s ID (depending on

programming) is displayed. Ad-

just the volume as necessary.

INDIVIDUAL CALL - If an indi-

vidual call (a call directed to only

one radio) is received, the radio

will unsquelch on the assigned

channel and the "BSY" status

flag will turn on. "*INDV*", the

originators ID number, or the

caller’s name (if programmed) is

displayed and the "MSG" status

flag flashes. Adjust the volume

as necessary.

Responding to an individual call

prior to the programmed call-

back time-out period will auto-

matically direct the transmission

to the originating unit on an indi-

vidual basis.

The "MSG" status flag will re-

main flashing even after the indi-

vidual call time-out period

expires. On a Scan or System

model radio, press the SPC but-

ton (SPecial Call) to call the

originating unit back after the

time-out period has expired. The

originator’s ID or name will be

displayed. Follow the proce-

dures for sending a special call.

Sending A Message

1. Turn the radio on, set the receive

audio level and select the de-

sired system and group.

2. Observe the display for the ab-

sence of the "BSY" status flag to

ensure no one is transmitting on

the selected group.

3. Press and hold the PTT BUT-

TON. The radio will perform the

necessary signalling re-

quired to obtain a communica-

tion channel.

4. When the channel has been ac-

quired, the "TX" and "BSY"

status flags are displayed

and the channel access alert

tone (one beep) sounds.

5. Hold the radio approximately

three inches from the mouth and

speak into the microphone in a

normal voice.

6. Release the PTT BUTTON

when the transmission is com-

plete. If the transmission ex-

ceeds the programmed Carrier

unkey and an alert tone will

sound.

7. Listen for a reply.

Emergency Operation (Trunked Mode)

Receiving An Emergency Call

If the radio receives an Emergency Chan-

nel Assignment in trunked mode, an alert

tone sounds and the "EMG" status flag

starts flashing. Follow standard emergency

procedures.

Sending An Emergency Call

1. To enable an emergency trans-

mission, press and hold the

EMERGENCY BUTTON

(small red button near antenna)

for approximately one second.

The radio transmits an

emergency message until an

Emergency Channel Assign-

ment is received. Upon re-

ceipt, the "EMG" status flag

turns on and the radio begins

operating on the selected

group or the home group, de-

pending upon programming.

2. Press the PTT BUTTON and

speak into the microphone in a

normal voice.

3. Release the PTT BUTTON

when the transmission is com-

plete and listen for a reply.

4. When the radio receives a nor-

mal group channel assignment,

it will return to the previously se-

lected group.

Clearing An Emergency

An emergency can be cleared from a

System model radio if it is programmed

with supervisory privileges. To clear an

emergency from a supervisory System

model radio, press 2nd, CLR, and then the

EMERGENCY BUTTON all within one

second. The "EMG" status flag will turn off

when the emergency state has been

cleared by the trunked system.

Dynamic Regrouping

Dynamic Regrouping is a feature

which allows the System Manager to dy-

namically program new groups into se-

lected radios. Upon development of the

regrouping plan, the site controller sends

each radio the regroup plan number, knob

setting(s), and activate/deactivate com-

mands.

When the radio is regrouped, it will

alert the user and the display will indicate

"REGRP nn" (nn = 01 - 08 depending upon

the CONTROL KNOB setting).

If the regroup plan has deselect capa-

bility active on the selected system, press

the MONITOR BUTTON to toggle between

the group and regroup modes.

Wide Area System Scanning

The EDACS M-PA radio can be pro-

grammed for wide area system scan op-

eration for multi-site applications. Upon

the loss of the currently selected system’s

control channel, the radio can be pro-

grammed to automatically scan the control

channels of up to six other systems. If a

new control channel is found, the radio will

switch to the new system and sound an

alert tone. Group selection may change

upon switching to the new system.

The radio can also be programmed for

priority wide area system scan operation.

A priority system is assigned to each sys-

tem programmed into the radio. A radio

programmed in this manner will scan the

priority trunked system’s control channel

once every one, two, three or four minutes

(programmable). This priority scan timer is

reset each time the PTT BUTTON is

pressed.

Scanning Trunked Groups (Scan And

System Models Only)
