INTRODUCTION
This manual describes the operation of the
M-PA

two-wayFMSelect,Scan,andSystemmodel
portable radios.
Operating controls on the radio include a ro-
tatable control knob, rotatable volume control, a 4-
button keypad (Scan model) or 16-button keypad
(Systemmodel), push-to-talk, emergency and moni-
tor buttons. The on/off power switch for the unit is
located on the removable battery pack.
The 8-digit alphanumeric liquid crystal display
(LCD)onthefrontoftheradiodisplaystheoperating
status of the radio. This backlit display also has
status flags for indicating the various operating con-
ditions such as transmitter on, scanning, or emer-
gency mode enabled.
The exact operation of your radio will vary de-
pending upon the mode of operation, the radio’s
programming, andthe particular radiosystem. Con-
sult 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
heardandthe "ON" indicatorwillbe exposed. When
the radio is turned on, it willperform 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.
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
audiolevel. Minimumlevelsmaybeprogrammedinto
the radio to prevent missed calls due to too low of a
volume setting.
CONTROL KNOB
The rotatable 16-position CONTROL KNOB lo-
catedonthetopoftheradioisprogrammedtoselect

the operating channel, mode, or specific Channel
Guard encode/decode tones. See MODE/CHAN-
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 re-
turn operation to receive mode.
MONITOR BUTTON
The MONITOR BUTTON is used to unsquelch
the receiver. Momentarily pressing this button will
disable squelch and the receiver noise will be heard
in the speaker.
Ifprogrammedenabledfortheselectedchannel,
ChannelGuard(CG)and/orType99(T99)signalling
will be enabled when the channel is selected. If CG
and/or T99 are enabled, the appropriate status flag
"CG" and/or "T99" willturn on. TheMONITOR BUT-
TON may then be used to toggle CG and/or T99
betweendisabledandenabledbypressingandhold-
ing it for at least one (1) second; the appropriate
status flag will toggleon oroff. The MONITOR BUT-
TON is also used to reset T99 operation after a call
is received.
EMERGENCY BUTTON
The EMERGENCY BUTTON is the small red
button located on top of the radio near the antenna.
If this button is programmed for emergency opera-
tion,pressingit foratleast one(1)secondwillcause
theradiototransmitGE-STARemergencysignalling.
The "EMG" status flag will turn on. GE-STAR is
transmittedaccording to one ofseveraldifferent pro-
grammable methods. See EMERGENCY OPERA-
TION for details.

ALERT TONES
TheM-PAuses alerttones or"beeps"toindicate
various operating conditions. Alert tones may be
enabled or disabled via the menu mode if the
"ALERT" feature is programmed. See "ALERT"
MENU for details. The alert tones may be disabled
when the radio is programmed.
CARRIER CONTROL TIMER
This feature, programmable on a per channel
basis, prevents unnecessary channel traffic and ra-
dio damage in the event of a "stuck" mic. If the
programmed timer times-out during a transmission
the radio will sound an alert tone and disable the
transmission. Thebeepingtonewillcontinueuntilthe
PTT BUTTON is released. Releasing the PTT BUT-
TON resets the timer.
CHANNEL BUSY
If the radio is receiving a signal when the PTT
BUTTON is pressed, an alert tone will warn the
operator that the radio is receiving a carrier and the
transmission will not occur. "RX BUSY" is displayed
and the alarm is sounded as long as the PTT BUT-
TON is pressed. Thisfeature isprogrammableon or

EMERGENCY OPERATION
The radio may be programmed to transmit GE-
STARemergencysignallingwhentheEMERGENCY
BUTTON is pressed or from a UDC connected lan-
yard. If the EMERGENCY BUTTON is programmed
for GE-STAR emergency activation, press it for ap-
proximately one (1) second to activate the transmis-
sion. If the lanyard is programmed for activation,
follow the instructions provided with it. GE-STAR is
programmedtotransmitinoneofthefollowingmeth-
ods:

Turning the radio off and back on will reset
this condition.
•GE-STAR is sent on the selected channel
andtheradiolocksontothatchannel. Rotat-
ing the CONTROL KNOB will not change

SCANNINGCHANNELS(ScanandSystemmodels)
The M-PA may be programmed for non-priority
scan, dual-priority scan, or scan operation may be
disabled. Scan programming options include a key-
padenteredscanlistorafixedscanlist. Priorityscan
programming options include a fixed priority-one
channel or the selected channel as the priority-one
channel.
The radio may be programmed to scan only the
channels in the current mode or it may be pro-
grammed to scan across modes.
Scan rate will vary depending upon the number
of channels on the scan list and whether or not the
radio is programmed to scan for Channel Guard.
Fewer channels will result in a faster scan rate. All
scan functions are retained in memory when the
battery pack is removed.
The radio will not scan when the emergency
mode is enabled ("EMG" status flag is on).
Adding Channels To And Deleting Channels
From The Scan List
If the "SCAN A/D" menu is programmed, chan-
nels may be added to and deleted from the scan list
of each mode as follows:
1. Selectthedesiredmodeandchannel. Ifthe
selectedchannelis currentlyonthelist, the
"S" status flag will be on.
2. Press the MENU button until "SCAN A/D"
is displayed.
3. Press the SEL button until the desired pri-
ority indicator appears: "S" for non-priority,
"2" for priority-two, "1" for a priority-one, or
noindicatortoremovethechannelfromthe
scan list. If a new priority channel is se-
lected the previous corresponding priority
channel will become a non-priority scan
19

channel. One of the following messages
may be momentarily displayed:
"SCAN DIS" - –The radio is notprogrammed
to scan.
"FIXED P1" - –A priority-one channel has
been programmed into the
radio. A new priority-one
channel can not be selected.
"FIXD LST" - –A fixed scan list is pro-
grammed into the radio. It is
notpossibletochangethelist
without reprogramming the
radio.
4. Toaddordeleteadditionalchannels,repeat
steps 2 through 4.
5. Press the EXIT button to return to normal
operation.
Using Scan
Toggle scan on or off by pressing SCAN. The
"SCN" status flag turns on when the radio is scan-
ning.
TELEPHONE INTERCONNECT CALLS
SCAN Model
Telephone interconnect calls can be placed on
radio channels equipped with this capability. Each
channel programmed into the radio can be pro-
grammedfortelephoneinterconnectbyenablingitfor
DTMF dial operation. One (1) of the ten (10) pro-
grammed telephone numbers can be selected and
automatically dialled.
Communication takes place in a simplex mode.
In other words, the PTT BUTTON must be pressed
each time you wish to transmit and it must be re-
leased to receive.
Placing A Call
Ten(10)telephonenumberscanbeprogrammed
in the radio for automatic dial operation. Typically,
telephonenumbersprogrammedintotheradiobythe
maintenance personnel each have a specific name
(8 characters maximum) assign.For example: "OF-
FICE" or "HOME".To recall a number and complete
a call, proceed as follows:
