IINNTTRROODDUUCCTTIIOONN
This manual describes the operation of the Ericsson
GE EDACS

M-RK l portable radio. The M-RK l is a
synthesized, microprocessor-based, high-performance
portable FM radio providing reliable two-way communi-
cations for Enhanced Digital Access Communications
System (EDACS) trunking environments and conven-
tional communication systems.
In the EDACS or trunked system mode the user
selects a communications system and group. In this
mode, radio channel selection is transparent to the user;
it is controlled by digital communication with the EDACS
site equipment. This provides advanced programmable
features and fast access to communication channels.
In conventional mode, the user selects a radio chan-
nel 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 radio’s exact operation will depend on its current
operating mode, its programming, and the particular
radio system. Many features described in this manual
can be enabled or disabled through programming.Con-
sult the system administrator for the particular features
that are programmed into the M-RK l.

AALLEERRTT TTOONNEESS
The M-RK l radio alsoprovides audible alert tones or
"beeps’ to indicate various operating conditions. Alert
tones can be enabled or disabled through programming.
CCaallll OOrriiggiinnaattee
A short mid-pitched alert tone sounds after keying
the radio (afterpressing the PTTbutton).At this time, the
TX/BAT indicator lights red and, in trunked mode, the
BSY/SCN indicator lights green.This indicates the radio
has been assigned a workingchannelor it is transmitting
on a conventionalchannel and voice communication can
begin immediately. In conventional mode, this alert tone
may be delayed slightly after PTT activation due to
GE-STAR signalling if GESTAR is enabled through pro-
gramming.
AAuuttookkeeyy ((TTrruunnkkeedd MMooddee OOnnllyy))
The site calls the radio when a channel becomes
available after a call is placed in queue or if the PTT
button is released prior to a working channel assignment
1133

At this point, the radio automatically keys the transmitter
(autokey) for a short period to hold the channel and it
sounds a mid-pitched tone when it is clear to talk. The
operator should immediately press the PTT button to
keep the assigned channel.
CCaallll OOuueeuueedd ((TTrruunnkkeedd MMooddee OOnnllyy))
A high-pitched tone will sound and the BSY/SCN
indicator will flash green if a call request is placed in
queue after PTT activation. The receiving unit(s) also
hearthetoneto notifythemthatacallshouldbe received
shortly. If the PTT button is released when a call is
queued, the radio will autokey whenever a channel be-
comes available (see "Autokey").
SSyysstteemm BBuussyy ((TTrruunnkkeedd MMooddee OOnnllyy))
Three (3) low-pitched beeps will sound 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 attempted to a radio
that is transmitting. Release the PTT button and re-key
the radio to re-initiate the call request.
CCaallll DDeenniieedd ((TTrruunnkkeedd MMooddee OOnnllyy))
A low-pitched tone will sound at PTT activation if the
radio is not authorized to operate on the currently se-
lected system.
1144

CCaarrrriieerr CCoonnttrrooll TTiimmeerr
If the programmed time for continuous transmission
is exceeded, five (5) short high-pitched alert tones fol-
lowed by a long low-pitched alert tone will sound. The
transmitter will shut down shortly after hearing the alert
tones and the TX/BAT indicator will turn off Communica-
tion is interrupted.Release and re-key the PTT button to
maintain communications.This will reset the carrier con-
trol timer and turn the transmitter back on.
LLooww BBaatttteerryy WWaarrnniinngg
If the battery pack’s charge is/becomes low, a low-
pitchedtonewillsoundandtheTX/BATindicatorwillflash
red. The radio will continue to receive and transmit nor-
mally however, the battery pack should be charged or
replaced as soon as possible.If the radio is keyed during
this time, the TX/BAT indicator will lightcontinuously (not
flash) to indicate the radio is transmitting.
LLooww BBaatttteerryy AAlleerrtt
If the battery pack’s charge is too low to allow the
radiototransmit(usuaIlyaftera lowbatterywarning),the
radio will sound a low-pitched tone, (continue to) flash
the TX/BAT indicator red and disabIe any transmission.
The radio will continue to receive calls until the battery
pack is discharged beyond the point of operation.
1155

KKeeyy PPrreessss AAlleerrtt
A short low-pitched alert tone will sound if no action
is taken when a button is pressed. For example, if the
currentIy selected conventional channel has the channel
busy transmit lockout feature enable and the radio is
keyed when the channel is busy the radio will sound this
low-pitched alert tone to warn the operator that no trans-
mission is occurring.

Be fore turning the radio on, verify the antenna and
battery pack are properly connected.To turn the unit on,
rotate the POWER ON-OFF/VOLUME knob clockwise
out of the detent position. If enabled through program-
ming, a short beep will sound to indicate the radio is
operational. The radio will begin operation on the cur-
rently selected system/group or channel.

The M-RK l is programmed withone of the following
system/group/channel selection methods:
•
The radio is programmed with up to sixteen (16)
different system/group or channels that are selected
with the SYSTEM/GROUP/CHANNEL knob.Radios
programmed in this manner use the OPTION button
1166

to provide a toggle feature or to enable special call
mode.
•
The radio is programmed with up to thirty-two (32)
different system/group or channels selected in two
(2) different banks of sixteen (16). If programmed in
this manner, the OPTION button is used to toggle
between the two banks and then the SYS-
TEM/GROUP/CHANNEL knob is rotated to select
thesystem/grouporchannel.Nospecialcalls canbe
initiated by a radio programmed in this manner

squelch) on the assigned working channel and the
BSY/SCN indicator will light-up green. Adjust the
volume as necessary.
4. GROUP CALL - If the call is a group caIl and a repIy
is necessary, follow the instructions outlined in the
section entitled "Sending A Call" (Steps 2 - 3).
INDIVIDUAL CALL - An individual call is a call di-
rected to only one radio. The radio may be pro-
grammed to ring when it receives a call of this type.If
not answered, the ring will continue until the call-back
hangtime (programmable) expires.
Responding to an individualcalIprior tothe call-back
hangtime time-out will automatically direct the call to
the originating unit on an individual basis. The OPT
indicator lights green during the call-back hangtime.
