SAFETY INFORMATION
The operato r of any mobile radio should be aware of ce rtain hazards
commo n to the opera ti on of ve hi cula r ra di o tran smi ssi ons.
A list of po ssibl e ha za rds ar e:
1. Explosive Atmosphe res
Just as it is dangerous to fuel a vehicle with the motor running, be
sure to turn the radio off while fueling the vehicle. Do not carry
contai ners of fue l in the trunk .
2. Interferenc e to Vehicular Elec troni cs Systems
Electronic fuel injection systems, electronic anti skid braking systems, etc., are typical of the type of electronic devices that may
malfun ction due to th e lack of prote ction from radio fre quency en ergy
present when transmitting. If the vehicle contains such equipment,
consult the dealer for the make of the vehicle and enlist his aid in
determining if such electronic circuits perform normally when the
radi o is tra ns m it ti ng.
3. Dynamite Blasting Caps
Dynamit e blasting c aps may be caused to expl ode by operating a ra dio
within 50 0 feet of the blastin g caps. Alwa ys obey the "Turn O ff Two
Way Radios" signs posted where dynamite is being used. When
transp ort ing blasti ng c ap s in your veh ic le:
a. Carry the blasti ng c a ps in a closed metal box wit h a soft lining.
b. L e ave t he r ad i o OFF whenever the blasting caps are being put
into or removed from the vehicle.
4. Radio Fre que ncy Ene rgy
To prevent burns or related physical injury from radio frequency
energy, do not operate the transmitter when anyone outside of the
vehi cl e is wi th in t wo fe et of th e antenna .
5
5. Liquefied (L P) Ga s Powere d Vehicles
Mobile radio installations in vehicles powered by liquefied petroleum
gas with the LP gas container in the trunk or other sealed-off space
withi n the int erior of the ve hicl e must co nform to the stand ard whic h
requires that:
a. The space contai ni ng the radi o eq uip me nt shal l be isol ate d by a
seal from the space containing the LP gas container and its
fittings.
b. Outside fi lling connec tions shall be used for t he LP gas con tainer .
c. The LP gas containe r shall be vented to the ou tside of the vehic le.
SAFE DRIVING RECOMMENDATIONS FOR USERS OF MOB ILE
RADIOS
Read the literature on the safe operation of the radio.
• Keep both hands on the steerin g wheel and the m icrop hone in it s crad le
whenever the vehicle is in motion.
• Place calls onl y when veh icle is stoppe d. Use recal l diali ng to spee d the
time it takes to call.
• When ta lking fro m a moving ve hicle is unavoida ble, drive in the sl ower
lane. Keep conversations brief.
• If conversation requires taking notes or complex thought, stop the
vehicle in a safe place and co ntinue the call.

INTRODUCTION
This manua l descr ibe s how to use the T r unke d MDX Mob ile R adio. The
MDX is a synthesized, microprocessor-based, high performance mobile FM
radio providing reliable two-way communications in trunking environments.
Direct mobile to mobile communication, when out of repeater range, is also
provided.
In a trunked environment the user selects a communications system and
group. In this mode, audio channel selection is transparent to the user and is
control led via digital commun ication with the system cont roller . This provides
advanc ed progra mm able feature s and fast acc ess to com munic ati on cha nnels.
In the trunke d m odes of opera tion th e user c an pro gra m th e ta lk gro ups to
transmit and receive Aegis Digital Voice or the highly secure Aegis VGE

ALERT TONES
The trunked MDX radio generates a set of unique alert tones to indicate
operat ing status. The follo wing sec tion iden tifies an d descri bes the ale rt tones
used in the MDX radio for trunke d applic atio ns.
SELF CHECK
TEST ALERT
One beep is sounde d afte r the ra dio is tu rned on to
indicate that the radio has passed the self diagnostic
test. Optional in PC programmer .
CALL
ORIGINATE
ALERT
If programmed, a short tone is sounded whenever
the Push-To-Talk (PTT) button is keyed and the
rad io has acq uired a channe l. This tone ind icates
the user may begin communications.
AUTOKEY When the PTT is keyed to place a call on the
system, but the PTT is released before getting to
the channel (e.g. a queued call), the radio automatically ke ys on the channel when it gets the assignment. The radio generates a long beep and holds
the transm itter keye d for two seconds. Pressing the
PTT b utton keeps the channel and sends the me ssage before this two second time-ou t has expired.
OUT OF RANGE /
SYSTEM
INOPERATIVE
A single low pitche d tone wil l sound imm edia tel y
after the PTT switch is keyed indicating the radio
is out of range of the repeater. The radio tries to
place the call for a short period (3 seconds) after
the initial attempt. The radio generates a second
low pitched tone when it gives up trying to place
the call. The system is off the air or the radio nee ds
servicing when the radio is within calling range,
and these tones are heard.
CALL RECEIVED If programmed, a single alert tone sounds when a
group call is received and a two tone alert (one high
followed by one low tone) is sounded for an individua l ca ll .
15
CALL DISABLED
ALERT
You will hear a cont in uous l ow pit che d t one whe n
your radio is set to an Rx (decode) only
group/channel and you press PTT on the microphone . This tone indi cates tha t you ar e not allowe d
to plac e a cal l on this setting.
CARRIER CONTROL
TIMER
The Car rier Contr ol Tim er al ert is a low pi tched
tone you will hear whenever you have kept the
PTT button continuously pressed for a pre-programmed length of time. Four warning beeps preceed the tone and transmitter shutdown. The
transmitter shuts down when the steady low
pitched tone starts, interrupting communications.
To maintain communications, release and re-key
the microp hone. Thi s resets the timer an d turns the
transmitter back on. The CCT is a built in precaution against ex tende d use of the system .
TRUNKED ALER T TONE SET S
There are two trunked alert tone set s: single and continuous. The trun ked
MDX radio can be programme d to use either set.
Single Al ert Tones
CALL QUEUED If one short, high pitched tone sounds after the
transmitter is keyed, it indicates the system has
placed the request in a queue. This tone sounds at
bo th the tran smitting and r eceiving end th at a call
is forthcoming. If the PTT is unkeyed whi le in the
queue, the radio will automatically key push-totalk when a channel becomes available (see
AUTOKEY).
SYSTEM BUSY If you key the PTT bar and hear three short, me-

the system.
switch is keyed and the request is denied by the
system. This happens if the unit is an invalid user
or if the uni t is requesting an unavailabl e servi c e.
Continuous Ale rt Tones
CALL QUEUED If you hear two short, high pitched bee ps after you
key the microphone, the system has placed your
request in a queue. The tones sound at both your
transmitting unit and the receiving unit(s). This
indicates to the receiving unit(s) that they will
recei ve a call s hortl y . T hese tones will repe at ev er y
half secon d a t the c a lle r’ s r ad io unt il Pu sh-To-Tal k
is released. If you unkey the microphone while in
queue, your radio will autokey when a channel
becomes available [Automatically key (push-totalk), see AUT OKEY] .
SYSTEM BUSY If you key the m icrophone and hear f our s hort, l ow
pitc hed b eep s, the r ec eiv ing pa rt y is al re ad y o n t he
system or the system is busy and its queue is full.
The busy ton e sequ en ce is re pea te d as long a s yo u
continu e to press the PTT switc h. You must r elease
and re-key the PTT switch to access the syste m.
CALL DENIED If you hear five long low pitched tones when you
key the microphone, y our request has been denied
by the system. this happens if you are an invalid
user or if you are requesting an unavailable service.
END OF "CALLBACK" After receiving a Multi-Group Decode, Scan or
Individual Call, you will have a pre-programmed
period to respond back to the caller. At the end of
this period , the radio will sound two shor t tones to
ind icate a re turn to normal op erat ion, and the received call can no longer be answered directly .
OPERATING NOMENCL ATURE
TRUNKED OPE RATION
Tru nke d ope ra tion ref er s to the use of a set of r ad io fre que nc y c hanne l s by
multiple user groups. Users may place and receive calls to single or multiple
users without being moni to re d by othe r users (or grou p) on the system .
CONVENTIONAL OPERATION
All radios o n a convent ional system operate in one of two modes: repeate d
or talk-around. T alk-around (also referred to as "direct mode") provid es a direct
radio-to-radio short-range communications link. It is intended to maintain
communications outside of the main system coverage area. Trunked features
(such as call queuein g and system scan) are not available in conventional mode.
Conventi ona l mode oper at io n shoul d only be used for testi ng pur pose s.

System The term system refers to the particular group of
station re pea ters and set of gro up/spec ial cal ls providing service to the radio. Radios can be preprogramm ed to work in diff erent syste ms by changing
the systems selection or through wide area roaming.
Group Or
Subfleet
A group of users share the same preprogrammed
group identification number in their radios. All
rad ios in the same group rec eive cal ls pl aced by
any one radi o in the group .
Fleet A fleet of users consists of multiple groups (sub-
fleets). Radios can be preprogrammed to make
fleet calls to simultaneously access multiple user
groups.
Agency An agency is composed of multiple fleets. Radios
can be preprogrammed to initiate agency calls to
access multiple fleets.
Individual Call Every radio in the system has been assigned a
preprogrammed, unique individual identification
code. A radio can be programmed to individually
call another particular radio from the S peci al Call
Menu.
Wide Ar ea System Oper ation (O ptional)
This func tion applie s when systems ar e networked together in a mult i-site
configuration. In this mode, calls are automatically routed to the proper system.
You may notice a delay when you press the PTT button while the system is
connecting t he corre ct sites. The BS Y indi ca tor will be on, indica ting you are
on the voice channel. In this mode, you can release and press PTT again to
override the del ay. This gets you onto the system , but does not guarantee that
everyon e will hear the message.
When in the multi- site mode , your radi o may be prog ra mme d to look fo r
alternate systems when you go out of range of the currently selected system.
If an alternate system is found, the radio locks onto the system and
automa ticall y select s the correct informa tion for this new syste m. Alterna tel y ,
the radi o may be progra mm ed to reve rt to a conve ntiona l ch anne l when o ut of
ran ge of th e tr u n k e d system.
18
Each trunke d syst em may a lso ha ve a priority tru nke d sy ste m associ at ed
with it when set to a system with a priority system programmed, the radio
periodi cal ly che cks for the pr iorit y syste m. If found, it au toma tical ly swi tche s
to tha t syst em. Th e tim er i s re set eve ry t ime the PTT butto n i s pr essed t o avoi d
inter ru pting a conversa ti on.
ProSou nd
The radio may be programmed for ProSound system scan operation for
multi-site applications. ProSound scanning is an enhanced replacement for
wide area system scanning. This algorithm insures that the radio continually
receives high quality audio. When the selected system degrades to a
pre-progr am med lev el, th e ra dio begi ns se arch ing for the best a djace nt syste m
on a part time basis. Once a better system is found, the radio changes to the
new system and sounds a tone. Should the control cha nnel be lost completel y ,
the radio will scan the adja cen t system s unti l a suitable one is found .
Telephone Interconnect
This featu re allows you to init iate preprogram med Special Cal ls or receive
telephone calls through you r radio if the system is configure d for this ope ration.
BASE/UNIT OPERATION
This pre-p rogram me d option is used in some fleet s so units c an only he ar
and talk to a base di sp at c h unit , not to other radios in th e group. In this mode
of ope ra tion, when a ra di o in a par ti cu la r gr oup is t al ki ng t o the ba se di sp at c h
unit, all other radios in that group will receive a "System Busy" tone if they
try to access the system.

27
METHOD 3: Returning the Micro phone to the hang- up bracket (enabled
through prog ramm i ng).
NOTE
If a channel disconnect occurs before the conversation ended, the call
must be initiated again. To avoid confusion it is recommended that a
procedure be set up so that the originator of t he call is the one designated
to re-establish communications. Two or more operators originating a
call simultaneously may acquire two different channels making
communi c at ion impossib le .
MOBILE DAT A TERMINAL INTERFACE (OPTIONAL)
Your MDX radio is capable of interfacing with a Mobile Data Terminal/Computer Host. When placing or receiving data calls, the MDX displays

If the pre -programm e d groupset on the currently select ed system contains
an EMER GENCY/HOME group a nd the radio is in dynamic regroup, the radio
will exit dynam ic regr oup and dec lare th e emerg ency on the HOME group . If
no EMERGENCY/HOME group is present, the radio will declare the emergenc y on the cur re ntly select e d dyna m ic regro up group.
AEGIS OPERATION
NOTE
Each talk group can be programmed for Aegis Digital Voice or Aegis
VGE Encrypted Digital Voice (private) mode of operation by
programming the "KEY" variable
When pro gra m med "DIG", a talk gr oup wi ll onl y t ransmit Aegis Digi ta l
Voice.
When programmed "1-6", a talk group will transmit Aegis VGE
Encrypted Digital Voice. Valid cryptographic keys must be loaded into
the MDX using the Universal Key Loader. The "PVT" icon (indicating
encrypted mode is on) can be turned on and off using one of the AUX
keys or by chosing "FORCED" as the mode of operation in the
programmer.
VOICE MO DE S
Each system in the radio is program med for Aegis communic ations. Aegis
progra mmed syste ms have two (2 ) diff erent voi ce mode s: private and digit al.
[A clear vo ice (Analog) mode is programmable for te st purposes]. The v oic e
modes are programmed on a per-group basis within each trunked system. A
radio must be equipped with the encrypt/decrypt option before it will operate
in Aegi s pri vate m ode.

Message trunke d group cal ls and i ndivid ual ca lls will be answer ed bac k in
the mode in which they were received, assuming the call or hang time is still
active.
When using the "call back" fe ature to respond to an I-Call, the call will be
transmi tt ed in the mode in whic h it was re cei ve d.
Scanned Group Calls
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 wi ll transmi t back in the same mod e in which th e call was rec eived. 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, only the first
occurre nce of the gr oup wi ll be use d.
CONVENTIONAL OPERATION
Outside Addr ess
The same outside address must be programmed in the transmitting and
rece iving radios when Aegi s digit al operation is enabled . If addr ess is not
correc t, the ra di os wil l not co mm un ic a te.

OPERATING TIPS
The following conditions tend to reduce the effective range of two-way
radios and should be avoi de d whene ve r possib le.
Operating the radio in low areas of terrain or while under power lines or
bridges.
Obstructi ons such as mo untains or build ings be twee n the vehi cle sen ding
and the system/p er son rece ivin g the m essa ge.
In areas whe re transmission or re ception is poor , some improvem ents may
be obta ined by insuring that the ante nna is ve rtical (pa rticular ly if a g lass mount
antenn a is used). Moving a few yards in anot her direction o r moving to a hig her
elevation may also improve communications.
