IINNTTRROODDUUCCTTIIOONN
This manual describes how to use the EDACS M-RK II Port -
able Radio. The M-RK II is a synthesized, microprocessor-based,
high performance portable FM radio providing reliable two-way
communications in both the Enhanced Digital Access Commu -
nications System (EDACS) trunking environment and conven -
tional 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.

UUSSEERR IINNTTEERRFFAACCEE
The M-RK II operating controls are located on the radio’s
front, top and left panels. A 15-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 ON-OFF/VOLUME
control knob and a protected red EMERGENCY button. An OP -
TION 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 manual number entry for individual
calls, access to a telephone interconnect system, and activa -
tion of various EDACS or conventional 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.

This section describes the primary function of the button
and knob controls. Other functions associated with these con -
trols are detailed in later sections.
SSYYSSTTEEMM

// CCHHAANNNNEELL
KKNNOOBB
Selects systems or groups/channels
(depending on programming). This is a 16-
position rotary knob. See SYSTEM/
GROUP/CHANNEL SELECTION for de -
tails.
PPOOWWEERR
OONN--OOFFFF
// VVOOLLUUMMEE
KKNNOOBB
Applies power to the radio and adjusts
the receiver’s volume. Rotating the con -
trol clockwise out of detent applies
power to the radio. A single alert tone
sounds (if enabled through programming)
to indicate the radio is operational.
Rotating the control clockwise increases
the volume level. Minimum volume levels
may be programmed into theradio topre -
vent missedcallsdue to alow volume set -
ting. While adjusting the volume the dis -
play will momentarily indicate the volume
level (i.e. VVOOLL == 3311 ). The volume range is
from a minimum programmed level of zero
(displayed as OOFFFF in the display) up to 31
which is the loudest level.
EEMMEERRGGEENNCCYY
BBUUTTTTOONN
Provides single button emergency chan -
nel access. See the EDACS and conven -
tional emergency sections for more de -
tails.

modes the OPTION button can be usedto
recall the last phone number or radio ID
entered.
CCLLEEAARR
// MMOONNIITTOORR
BBUUTTTTOONN
Serves several purposes depending on
the operating mode. In trunked mode, the
CLEAR/MONITOR button exits the cur -
rent operation and removes all displays
associated with it. The radio and display
then return to the group receive state. In
conventional mode, pressing this button
unmutes the receiver so activity on the
selected channel can be monitored. When
pressed and held for approximately 3
seconds, this button toggles conven -
tional channel decoding/encoding (Chan -
nel Guard, Digital Channel Guard, T99) on
and off if programmed for the selected
channel.
PPUUSSHH--TTOO--TTAALLKK
BBUUTTTTOONN ((PPTTTT))
Enables the radio’s transmitter. Releas -
ing PTT returns the radio to the receive
mode.
KKEEYYPPAADD
The keypad layout is similar to a standard telephone keypad
but with three additional buttons at the top for a total of 15
keys. In addition to numbers, most of the keys have special
functions and are labeled as such using a symbol or abbreviated

word describing its primary function. Numeric entry is a secon -
dary function of the keys. Each key is described below.

tails.
DDIISSPP Inverts the display’s two alphanumeric
character lines for viewing from above;
useful when the radio is attached to the
user’s belt.
DDIISSPPLLAAYY
The radio’s display is shown below. The two character lines
are used to display system, group and channel names and also
operational messages to the user. Each line contains eight al -
phanumeric character blocks. The 15 status indicators are used
to show the various operating conditions of the radio. If the
SSCCNN
1133

display back-lighting is programmedon, the displaywill illuminate
for a short period when any of the controls are operated.
The two display lines can be inverted to permit easy viewing
if the radio is worn on a belt or placed into a vehicular charger.
Press DDIISSPP once to invert the character lines, press DDIISSPP again
to return to the normal display. Refer to the MENU section to
change the display’s contrast.
