BASESTATIONINSTALLATION

ANTENNACONNECTION

The type of the antennasystem,consistingof the

antenna, ground,and feed line,will greatlyaffectthe

successfulperformanceof the radiotelephone. Usea

properlyadjusted50 Q antennaof good qualityto let

your radiotelephoneperformat its best. Usea

good-quality50 Q coaxialcableanda first-quality

connectorforthe connection. Matchthe impedanceof

the coaxialcableandantennasothatthe SWRis 1.5:1

or less. Allconnectionsmustbe clean andtight.

Whilethe radiotelephone'sprotectioncircuitwill activate

ifthe SWR is greaterthan 2.5:1,do notrelyon

protectionto compensatefor a poorlyfunctioning

antennasystem. HighSWR will causethetransmit

outputto drop,andmay leadto radiofrequency

interferenceto consumerproductssuchasstereo

receiversand televisions. Youmayeven interferewith

your own radiotelephone. Reportsthat yoursignalis

garbledor distorted,especiallyat peak modttlation,may

indicatethat your antennasystem is not efficiently

radiatingthe radiotelephone'spower. Ifyou feela tingle

from the radiotelephone'scabinetor the microphone's

metalfittings when you modulate,you can be certain

that, at the least,your coax connectoris looseat the

rearofthe radioand, atthe worst,your antennasystem

is not efficientlyradiatingpower.

CAUTION:

. Transmittingwithoutfirstconnectinganantennaorothermatched

load may damage the radiotelephone. Always connectthe

antenna to theradiotelephonebefore transmitting.

. Usealightninga"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 isrequired,

against whichthe antenna system can operate. Bothof

these conditionscan be met byprovidinga good earth

groundforyourstation. Buryone or moregroundrods,

or a large copper plate under the ground,and connect

thistothe radiotelephoneGNDterminal. Use heavy

gauge wireor a copper strap, cut as short as possible,

forthis connection. Allconnections mustbe clean and

tight.

DCPOWERSUPPLYCONNECTION

Inorderto use this radiotelephone,youwillneed a

separate 13.6VDCpowersupplythat must be

purchased separately. DONOTdirectlyconnect the

radiotelephoneto an ACoutlet! Use the supplied DC

powercable to connect the radiotelephoneto a

regulatedpowersupply. Donotsubstitutea cable with

smallergauge wires. The currentcapacity ofyour

powersupplymustbe 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 untilthe 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: Replaceblownfuses only after investigating and

correcting the cause of the failed fuse. Always replaceablown

fuseby anew fuse with thespecifiedratings.

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 pick a 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 line that 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 withthe

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 itfrom 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. In particular, 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 ofthe passenger compartment, use a rubber

grommet to protect the cable from abrasion. The entire

length ofthe cable must be dressed so itis 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. Ifthe 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: If you use the radiotelephone for along 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 ablown

fuse by anew fuse with the specified ratings.

GROUNDCONNECTION

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.

the busy channel approximately three seconds later.

If the channel is still busy, Scan waits another three

seconds then resumes scanning. If the channel is

not busy three seconds after stopping, Scan

resumes immediately.

Carrier-operatedScan: The radiotelephone

remains on the same channel until the signal drops,

then Scan resumes approximately two seconds later.

Select your preferred Scan Resume method via

Menu No. 05. The default is Time-operated.

Note: Carrier-operated Scan is automatically used for scanning

in Selective Call mode. However, when asignal is received,

scanning stops only during the unmuted period.

KPE-1 SELECTIVECALLUNIT(OPTIONAL)

After the Dealer installs the optional KPE-1 Selective

Call Unit, you can place calls to other stations by using'

the Microphone keypad to "dial" their unique

Identification code. You can also receive calls from

other stations that have dialed your Identification code.

In addition, Group calls allow you to call and

communicate with a group of stations in your system.

With a single call, you can contact a number of stations

at the same time, and transmit a message that will be

heard by all of these stations. The "*" symbol is used

as a wild card when programming Group codes. For

example, sending the Group code "*0*" would allow

you to contact all stations that have the number "0" in

the second digit of their Identification codes.
