IINNTTRROODDUUCCTTIIOONN

This manual describes how to use the EDACS M-RK II Scan
Portable Radio. The M-RK II Scan is a synthesized, microproces
sor-based, high performance portable FM radio providing reliable
two-way communications in both the Enhanced Digital Access
Communications System (EDACS) trunking environment and
conventional communication systems.

In the EDACS or trunked system mode, the user selects a
communications system and group. In this mode, channel selec
tion is transparent to the user and is controlled via digital
communication with the system controller. This provides ad
vanced programmable features and fast access to communica
tion channels.

In the conventional mode, the user selects a channel and

-

-

-

-

directly communicates on that channel. In this mode, a system
refers to a set of channels. A channel is a transmit/receive radio
frequency pair.

The exact operation of the radio will depend on the operating
mode, the radio’s programming, and the particular radio system.
Most features described in this manual may be enabled or dis
abled through programming. Consult the system administrator
for the particular features that are programmed into the M-RK
II Scan.

UUSSEER R IINNTTEERRFFAACCEE

The M-RK II Scan operating controls are located on the
radio’s front, top and left panels. A 6-button keypad, liquid
crystal display (LCD) for radio status information, microphone
and speaker are on the front panel. The top panel houses a
rotary SYSTEM/GROUP/CHANNEL knob, POWER ON­OFF/VOLUME control knob and a protected red EMERGENCY
button. An OPTION button, CLEAR/MONITOR button and the
Push-To-Talk (PTT) button are all located on the left side panel.
The Universal Device Connector (UDC) is located on the right
panel and is used while programming the radio and for accessory
connection.

The keypad is used for activation of various EDACS or con
ventional features such as menu selection or scan operations.

The display has two, eight-alphanumeric-character lines
used to show the operational mode of the radio. 15 status
indicators, used to indicate various operating conditions such
as transmitter on, channel busy, scanning, or low battery, are
located above and to the right side of the character lines within
the display. A back light illuminates the display and the keypad
for nighttime use.

UUNNIIVVEERRSSAAL L DDEEVVIICCE E CCOONNNNEECCTTOOR R ((UUDDCC))

The Universal Device Connector (UDC) provides connections
for external accessories such as a headset or a speaker-micro
phone. When the radio is locked in a vehicular charger/repeater
the UDC provides the audio and control connections between
the radio and the vehicular charger/repeater. The UDC is also
used to program and service the radio.

AALLEERRT T TTOONNEESS

-

The M-RK II Scan radio also provides audible alert tones or
"beeps" to indicate the various operating conditions. These alert
tones can be enabled or disabled through programming.

2211

CCaall ll OOrriiggiinnaattee

A short mid-pitched alert tone sounds after keying the
radio (Push-To-Talk button is pressed). This indicates the radio
has been assigned a working channel or that the radio is trans
mitting on a conventional channel and voice communication may
begin immediately. In conventional mode, this tone may be de
layed after the PTT button is pressed due to GE-STAR signalling
(if enabled through programming).

AAuuttookkeey y ((TTrruunnkkeed d MMoodde e OOnnllyy))

After being placed in queue or releasing the PTT button prior
to a working channel assignment, the site calls the radio when a
channel becomes available. At this point, the radio automatically
keys the transmitter (autokey) for a short period to hold the
channel. The radio sounds a mid-pitched tone when it is clear to
talk; immediately press the PTT button to keep the assigned

-

-

channel.

CCaall ll QQuueeuueed d ((TTrruunnkkeed d MMoodde e OOnnllyy))

A high-pitched tone after pressing the PTT button indicates
the system has placed the call request in the queue. The receiv
ing unit(s) also hear the tones, indicating they will receive a call
shortly. If the the PTT button is released, the radio will autokey
whenever a channel becomes available (see Autokey).

SSyysstteem m BBuussy y ((TTrruunnkkeed d MMoodde e OOnnllyy))

Three low-pitched beeps will be heard if the radio is keyed
when the system is busy, if no channels are available for sending

-

the message, if the call queue is full, or if an individual call is being

2222

attempted to a radio that is transmitting. Releasing the PTT
button and re-keying initiates a new channel request.

CCaall ll DDeenniieed d ((TTrruunnkkeed d MMoodde e OOnnllyy))

If the radio is keyed and a low pitched tone is heard then the

radio is not authorized on the system that has been selected.

CCaarrrriieer r CCoonnttrrool l TTiimmeerr

If the programmed time for continuous transmission is ex
ceeded, five short high-pitched warning tones followed by a long
low-pitched tone will be heard. The transmitter will shut down
shortly after hearing the alert, interrupting communications.
Release and re-key the PTT button to maintain communications.
This will reset the carrier control timer and turn the transmitter
back on.

LLoow w BBaatttteerry y WWaarrnniinngg

A low-pitched tone is heard and comes on indicating
that the battery voltage is low. The radio will continue to receive
and transmit.

-

LLoow w BBaatttteerry y AAlleerrt t ((TTrraannssmmiit t LLoocckkoouutt))

If the radio is keyed and a low-pitched tone or two tones
repeated until PTT or CLEAR button is pressed (either condition
is pre-programmable) is heard and LOW BATT is displayed, the
battery is discharged and the radio will not transmit. The radio
will still be able to receive calls until the battery is discharged
beyond the point of operation, after which the battery will need
to be recharged to resume normal operation.

BBAATT

2233

KKeey y PPrreess ss AAlleerrtt

A short tone or "beep" sounds to indicate a key has been
pressed. A short low-pitched tone indicates no action was
taken because the key is not active in the current mode.

OOPPEERRAATTIIOONN

TTUURRNNIINNG G OON N TTHHE E RRAADDIIOO

Rotate the POWER ON-OFF/VOLUME knob clockwise, out of
detent to turn the radio on. (Ensure the antenna and battery
pack are properly connected prior to power on.) A short beep (if
enabled through programming) indicates the radio is ready for
operation. The display indicates, if programmed, the last se
lected system name on line one and the last selected group or
channel name on line two.

In the EDACS trunked environment, upon acquisition of the
control channel, will come on. If communication with the
system’s control channel cannot be established, will not
turn on. This may occur if, for example, the radio is out of range
of the trunking site. It may be necessary to move to another
location or select another trunking system to reestablish the
control channel link for trunked mode operations.

Channels which have been previously added to the scan list
on a per system basis may be scanned. The selected channel is
scanned (if enabled through programming) whether or not it is
in the scan list. Each conventional system’s channel scan list is
retained in memory when the radio is turned off or when the

XXMMIITT

battery pack is removed.

The scan rate will vary depending upon the number of chan

­nels in the scan list and whether or not the radio is programmed
to scan for channels with decoding enabled. Fewer channels will
result in a faster scan rate. If programmed for dual-priority scan
operation, the priority-one, priority-two and the remaining scan
list channels are scanned. Once a signal is detected and the
correct encoded squelch signal is decoded (if programmed), the
radio receives the message and displays the received scan chan

­nel. At the same time, scanning continues on the priority-one
and priority-two channels. Should the priority-one or priority­two channel carrier, regardless of encoded squelch decoding, be
detected while a non-priority channel is being received, the dis

Aegis clear and Voice Guard clear modes are identical voice
modes in which the radio transmits and receives only clear (ana
log) voice signals. These analog signals are non-digitized and
non-encrypted. Clear mode transmissions can be easily moni
tored by unauthorized persons. Groups or channels pro
grammed for clear operation cannot transmit or receive Aegis
digital or private messages.

AAeeggiis s DDiiggiittaal l MMooddee

Aegis digital mode allows the radio to transmit and receive
digitized voice signals. Aegis digital signals provide improved
weak signal performance and they cannot be easily monitored
with a standard receiver. Groups and channels programmed for
Aegis digital operation transmit only digital signals. Private calls

-

-

-

cannot be received or transmitted when the radio is in the Aegis
digital mode because the radio does not know the cryptographic
key used. Message trunked group calls and individual calls will be
answered back in the mode they were received, assuming the call
or hangtime is still active. Individual, phone, all and emergency
calls will be transmitted clear if digital mode is disabled or inop
erative.

If receiving an analog message trunked call, the radio will
respond in analog mode during the hang time on the working

2.

If receiving an analog I-Call, the radio will respond in analog

3.

When using the "WHC" feature to respond to an I-Call (after
the hang time has expired), the call will be transmitted in
the mode defined by the system mode as programmed for
the current system if the ID being called is not in the I-Call

The Aegis private and Voice Guard private modes allow the
radio to transmit encrypted messages and receive clear or pri
vate transmissions. The radio will transmit private if the
group/channel is programmed for private operation and forced
operation is pre-programmed. If autoselect operation was pre­programmed and the radio is in private mode, the radio will trans
mit in the mode of the received call if the hang time is active. If
no hang time is active, the radio will transmit private.

Aegis transmissions cannot be received by a radio set to
receive a Voice Guard transmission. Accordingly, a Voice Guard
transmission cannot be received by a radio set to receive an
Aegis transmission.

Cryptographic keys are transferred to the radio using a

-

-

cryptographic Keyloader. Up to seven (7) different crypto
graphic keys, numbered 1-7, can be transferred from a Keyloader
and stored in the radio. An individual key is automatically se
lected on a per-group/channel basis according to the radio’s
programming. Groups and channels within Aegis systems can be

-

-

5555

programmed for keys 1-7. Groups and channels within Voice
Guard systems can be programmed for keys 1-7. Up to 8 banks
of 7 keys can be stored for Aegis (DES and VGE) systems and
up to 4 banks of 7 keys for Voice Guard systems. The bank is
specified per system.

DES radios require a DES Keyloader (Option V4025). VGE

radios require a VGE Keyloader (Option V4028).

When operating on a group or channel programmed for pri
vate mode, all transmissions will be private transmissions and
the radio will receive clear and private signals. The status
flag in the display turns on when the private mode is enabled. If
the selected group or channel is programmed for autoselect
capability, the mode may be toggled between private and clear

with the

m

key, then following the selection mode rules.

Radios programmed for forced private operation do not allow a
change of the transmit mode.

Receiving a scanned group call is the same as receiving a
selected group call. During the scan hang time, if the radio was
programmed for autoselect, it will transmit back in the same
mode it received the call. For example, if a clear group is entered
in the scan list, it will only receive clear calls. If the same group

PPVVTT

was available in private and entered in the scan list, it can receive
clear and private calls, provided autoselect was programmed in
the radio. The user can select transmitting on the scanned or
selected group. If a group is entered in the scan list more than
once and in different modes (clear, digital, private), only the first
occurrence of the group will be used.

PORTABLE DATA

The M-RK radios when operating in the EDACS configuration
permit either voice or data calls to be transmitted or received.
The radio can handle only one type of call at a time; however,
selection of either data or voice is selected transparently by the
operator through normal usage of the radio. Data communica
tions is not supported in the conventional mode.

The radios can be connected to Mobile Data Terminals (MDT)
or to a host computer. Any RS-232 compatible device that
supports the Radio Data Interface (RDI) protocol (Version 1.91
or greater) may be connected to the radio. Support for MDT’s

from one of these groups, it will "lock out", and not send
or receive calls from other groups for a programmed
period of 5, 10 or 15 seconds, permitting the user to
respond to the group call. (The radio may also be pro
grammed for no lock out period.) At the end of the
"lock out" period, the radio sounds two short low
pitched "beeps" and is again ready to receive a call from
any of the programmed groups. (Trunked Mode Only)

Every radio in the system is programmed with a unique
individual identification code. A mobile or personal unit
can be programmed to call another particular unit by
selecting the individual by name or ID number. (Trunked

Trunked Operation refers to the use of a set of radio
frequency channels by multiple user groups. By using
high speed digital data the radio goes to an unused
channel when a call is initiated and will also only re
spond to calls in the same user group. In this way
conversation privacy between user groups is assured.
