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
Encrypt e d Digit al Voi ce.
The exact operation of the radio will de pend on t he operating mode, the
radio’ s progra mming , and the particu lar radio system . Most feature s describe d
in this ma nua l ma y be e nabl e d o r disabled th roug h progr am m in g. Co nsult the
system a dmini stra tor for the part icul a r fea ture s tha t a re pro gra mme d into you r
