1 EXPLOSIVEATMOSPHERES
(GASES, DUST,FUMES,ETC.)
Turnoff and do not operatethe radiotelephonewhile
taking on fuel, or while parked in gasolineservice
stations. Do notcarry sparefuel containersinthe trunk
of your vehicle ifthe radiotelephoneis mountedin the
trunk area.
2 INJURY FROMRADIO FREQUENCY
TRANSMISSIONS
Do not operate the radiotelephone when anyone is
touching the antenna, or when anyone is standing within
two to three feet of the antenna, to avoid the possibility
of radio frequency burns or related physical injury.
3 DYNAMITE BLASTING CAPS ...
Transmitter operation can cause dynamite blasting caps
to explode if you operate within 500 feet of the blasting
caps. Turn off and do not operate the radiotelephone in
an area where blasting is in progress, or where "TURN
OFF TWO-WAY RADIO" signs have been posted. If
you are transporting blasting caps in your vehicle, make
certain they are carried in a closed metal box having a
padded interior. Do not transmit during the time that the
caps are being placed into or removed from this
container.
IMPORTANTNOTICE
Government law prohibits the operation of unlicensed
radio transmitters within the territories under
government control. Illegal operation is punishable by
fine or imprisonment or both.
Refer service to a qualified licensed or certified
technician only.

BASESTATIONINSTALLATION
ANTENNACONNECTION
The type of the antenna system,consistingof the
antenna,ground,and feed line,will greatlyaffectthe
successfulperformanceof the radiotelephone. Usea
properlyadjusted50 Q antennaof goodqualityto let
your radiotelephoneperformat its best. Usea
good-quality50 Q coaxialcableand a first-quality
connectorforthe connection. Matchthe impedanceof
the coaxialcable andantennaso that the SWR is 1.5:1
or less. Allconnectionsmustbe clean and tight.
Whilethe radiotelephone'sprotectioncircuitwill activate
ifthe SWR is greaterthan 2.5:1,do not relyon
protectionto compensatefor a poorlyfunctioning
antennasystem. HighSWR will cause thetransmit
outputto drop,and may leadto radiofrequency
interferenceto consumerproductssuchas stereo
receiversand televisions. Youmay even interferewith
your own radiotelephone. Reportsthat yoursignalis
garbledor distorted,especiallyat peak modttlation,may
indicatethat your antennasystem is notefficiently
radiatingthe radiotelephone'spower. Ifyou feela tingle
fromthe radiotelephone'scabinetor the microphone's
metalfittings whenyou modulate,you can becertain
that, at the least,your coax connectoris loose at the
rearof the radioand, atthe worst,your antennasystem
is not efficientlyradiatingpower.
CAUTION:
. Transmittingwithoutfirstconnectinganantennaorothermatched
load may damagethe radiotelephone. Always connect the
antenna to theradiotelephonebefore transmitting.
. Usea lightning a"estor toprevent fire, electricshock, or damage
to theradiotelephone.
GROUNDCONNECTION
Atthe minimum,a good DCground is requiredto
prevent such dangers as electricshock. Forsuperior
communicationsresults, a good RFground is required,
against whichthe antenna systemcan operate. Bothof
these conditionscan be met by providinga good earth
groundforyourstation. Buryone or more groundrods,
or a largecopper plate underthe ground,and connect
thisto the radiotelephoneGNDterminal. Use heavy
gauge wireor a copper strap, cut as short as possible,
forthis connection. Allconnections mustbe clean and
tight.

DCPOWERSUPPLYCONNECTION
Inorderto use thisradiotelephone,youwillneed a
separate 13.6V DCpowersupplythat must be
purchased separately. DONOTdirectlyconnect the
radiotelephoneto an ACoutlet! Usethe supplied DC
powercable to connect the radiotelephoneto a
regulatedpowersupply. Donot substitutea cable with
smallergauge wires. The current capacity of your
powersupplymust be 20.5Aor more.
CAUTION:
. BeforeconnectingtheDCpowersupplytotheradiotelephone,be
suretoswitchtheradiotelephoneandtheDCpowersupplyOFF.
. DonotplugtheDCpowersupplyintoanACoutletuntilyou
makeallconnections.
Firstconnect the DCpowercable to the regulated DC
powersupplyandcheckthat polaritiesare correct
(Red: positive, Black: negative). Then connect the
connectorized end of the DC power cable to the
DC 13.6 V power connector on the radiotelephone Rear
Panel. Press the DC power cable connector firmlyinto
the connector on the radiotelephone until the locking tab
clicks.
. ReplacingFuses
Ifthe fuse blows, determine the cause then correct
the problem. After the problem is resolved, only then
replace the fuse. Ifnewly installed fuses continue to
blow,disconnect the power plug and contact your
Dealer for assistance.
CAUTION: Replace blownfuses only after investigating and
correcting the cause of the failed fuse. Always
replacea blown
fuseby a new fuse withthespecified ratings.

MOBilEINSTAllATION
Install the radiotelephone in a safe, convenient position
inside your vehicle that minimizes danger to your
passengers and yourself while the vehicle is in motion.
For example, consider installing the radiotelephone
under the dash in front of the passenger seat so that
knees or legs willnot strike the radiotelephone during
sudden braking of your vehicle. Try to picka well-
ventilated location that is shielded from direct sunlight.
ANTENNACONNECTION
Before operating mobile, you must first install an
efficient, well-tuned antenna. The success of your
mobile installation willdepend largely on the type of
antenna and its correct installation. The radiotelephone
can give excellent results ifthe antenna system and its
installation is given careful attention.
Your choice of antenna should have a 50 Q impedance
to match the radiotelephone input impedance. Use low-
loss coaxial feed linethat also has a characteristic
impedance of 50 Q. Coupling the antenna to the
radiotelephone via feed lines having an impedance
other than 50 Q reduces the efficiency of the antenna
system, and can cause interference to nearby broadcast
television receivers, radio receivers, and other electronic
equipment.
CAUTION: Transmitting without first connecting an antenna or other
matched load may damage the radiotelephone. Always connect the
antenna to the radiotelephone before transmitting.
DCPOWERCABLECONNECTION
Route the DC power cable supplied with the
radiotelephone directly to the vehicle's battery terminals
using the shortest path from the radiotelephone. If
using a noise filter,it should be installed with an
insulator to prevent it from touching metal on the
vehicle. Itis not recommended to use the cigarette
lighter socket since some cigarette lighter sockets
introduce an unacceptable voltage drop.
To prevent the risk of short circuits, disconnect other
wiring from the negative H battery terminal before
connecting the radiotelephone. Confirm the correct
polarity of the connections before attaching the power
cable; red connects to the positive (+)terminal, black
connects to the negative (-) terminal. Use the full
length of the cable without cutting offexcess even ifthe
cable is longer than required. Inparticular, never
To antenna
removethe fuse holdersfrom the cable. After
completing radiotelephone connections to the battery,
then reconnect any wiring removed from the negative
terminal.
Ifthe power cable must be routed through a hole in the
vehicle chassis or body, for example inthe firewall at the
front of the passenger compartment, use a rubber
grommet to protect the cable from abrasion. The entire
length of the cable must be dressed so it is isolated from
heat and moisture. After the cable is in place, wind
heat-resistant tape around the fuse holder to protect it
from moisture. Tie down the full run of cable.
The vehicle battery must have a nominal rating of 12 V.
Never connect the radiotelephone to a 24 V battery. Be
sure to use a 12 V vehicle battery that has sufficient
current capacity. If the current to the radiotelephone is
insufficient, the Display may darken during transmission,
or transmit output power may drop excessively.
Only after completing the installation, connect the
radiotelephone's power supply connector to the DC
power cable. Press the connectors firmly together until
the locking tab clicks.
Note: Ifyou use the radiotelephone for a long period when the
vehicle battery is not fully charged, or when the engine is OFF, the
battery may become discharged, and will not have sufficient reserves
to start the vehicle. Avoid using the radiotelephone under these
conditions.
. ReplacingFuses
If the fuse blows, determine the cause then correct
the problem. Refer to additional information
including fuse ratings on page 2.
CAUTION: Replace blown fuses only after investigating and
correcting the cause of the failed fuse. Always replace a blown
fuse by a new fuse with the specified ratings.
GROUNDCONNECTION
Fora mobileinstallation,itis extremelyimportantto
securelyconnect a low-resistanceground strap fromthe
radiotelephoneGNDterminalto the metalvehicle
chassis. This connectionis necessary since mobile
antennas are physicallysmalland, therefore, less
efficientthan largerbase stationantennas. Ifa strap is
notavailable,a largegauge copper wireissuitable.
Alwaysclean paintor dirtfromthe vehicleconnection

ADJUSTINGSQUELCH
The purpose of squelch is to silence audio output from
the speaker when no signals are present. Setting the
squelch threshold too high causes the squelch to
remain closed while a weak signal is present. Setting
the threshold too low allows noise to be heard between
transmissions from other stations.
Turn the SQUELCH control to just eliminate the
background noise when no signal is present. If signals
are weak, set the control fully counterclockwise.
