INTRODUCTION
The M-PA radio is a high quality microprocessor con-
trolled synthesized portable FM radio. M-PA operation is
highlighted by the radio’s programming versatility. This al-
lows tailored operation of the portable radio to meet the
needs of the radio system and the individual users. Three (3)
different M-PA radio models are available: Select, Scan and
System.
The M-PA Select model radio is the basic version that
can be programmed with up to sixteen (16) channels. This
unit features an 8-digit alphanumeric liquid crystal display
(LCD) and a 16-position knob for channel selection. The
display is backlit for nighttime and low-level ambient light
operation.
Scan and System model radios have an LCD similar to
the Select model radio. A keypad is added to these radios (4-
button on Scan model, 16-button on System model) to pro-
vide additional features not available on the Select model
radio. These radios can be programmed with up to 192 dif-
ferent radio channels. Both also provide scan capability in-
cluding dual-priority scan, and DTMF telephone
interconnect of up to ten (10) preprogrammed numbers. The
telephone numbers can be recalled at will and initiated. The
System model’s numeric keypad allows editing of the ten
preprogrammed numbers and manual DTMF telephone in-
ter-connect dialing.
FEATURES
•
192-Channel Capability - Scan and System models
radios can be programmed with up to 192 channels
accessed in 12 modes (banks of channels) with 16
channels in each mode or 16 modes with 12 channels
in each mode. The Select model radio can be
programmed with a maximum of 16 channels.
•
Backlit Liquid Crystal Display - The 8-digit
alphanumeric LCD provides programmable
customization and feedback to the operator of various
operating conditions. Status flags located above and
below the digits alert the operator to various radio
conditions such as channel busy, transmitter in
operation, or a low battery condition. Scan and
System model radios have additional status flags for
scan operation. LCD backlighting can be enabled or
disabled on a per channel basis.
•
Rotary Control Knob - On Scan and System model
radios, the 16-position top-mounted Control Knob
allows easy selection of modes (banks of channels),
channels or Channel Guard (CG) according to how
the radio is programmed. On the Select model radio,
the Control Knob 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 normally factory installed for fifteen (15)
positions.
•
Volume Control Knob - This rotatable control
provides quick and easy adjustments to the volume
level. Minimum volume levels can be programmed
into the unit. This feature prevents missed calls due to
a low volume setting.
•
Monitor Button - This side-mounted button is used
to disabled squelch and if programmed for the
selected channel, it is used to toggle CG and/or T99
operation on and off.
•
Keypad - The Scan model radio has a 4-button
keypad on its front panel that provides scan and menu
control. The menus allow selection of the current
operating mode (bank of channels) and/or channel
depending upon the radio’s programming. The menus
also allow control of various other radio features such
as selection of stored telephone interconnect numbers
for auto-dial operation, and alert tone enable/disable
control. A System model radio has a 16-button
keypad. The top four (4) buttons are identical to the
Scan model keypad, providing scan and menu
control. The lower twelve (12) buttons form a
numeric keypad that allows manual DTMF telephone
interconnect dialing and editing of telephone
interconnect numbers stored in the radio. Select
model radios do not have a keypad.
•
Scan Capability - Scan and System model radios can
be programmed for non-priority scan or dual-priority
scan operation. Scan programming options include a
keypad entered scan list or a fixed scan list. Priority
scan programming options include a fixed
priority-one channel or the selected channel as the
priority-one channel. The radio can be programmed to
scan only the channels in the current mode (bank of
channels) or it may be programmed to scan across
modes. The Select model radio does not support scan
operation.
•
Telephone Interconnect Capability - The Scan and
System model radios can store up to ten (10)
telephone interconnect numbers for auto-dial
operation. These numbers are preprogrammed into
the Scan model radio. In the System model radio, the
numbers can be preprogrammed, operator-entered
and/or edited via the numeric keypad. The System
model’s numeric keypad also allows manual DTMF
tele phone interconnect dialing. The Select model
radio cannot initiate telephone interconnect calls.
