relative
to the operationand program-
ming
of the KX 99 Transceiver. It is
bestto reviewthe entire manual

General Information
This section contains a basic
description
of the KX 99 Transceiver
as well as suggestions and factors to
consider beforeusingthe KX
99.
Close adherence to thesesugges-
tions
will assure a moresatisfactory
performancefrom the equipment.
EquipmentDescription
The KX 99 isa 760 channel,
hand-heldVHF aircraftcommunica-
tions transceiver with a
1.5 watt
transmitter output. Inaddition, the
KX
99 iscapableof receiving 200 Nav
channels andall
7 NOAA Weather
Radio Broadcast channels. While
audio is receivedon all 200 Nav
channels, localizerinformationis not
processedon the 40 localizer
frequencies. VOR informationis
processedand displayedon the liquid
crystaldisplay(LCD) ineither a radial,
bearing,
or Course DeviationIndicator
(CDI) left-rightinformationformat.The
KX
99 containsa single receiver.
Therefore, it cannotperform the
COMMfunction and the NAV function
simultaneously.
The unit ispoweredby a self-
containedbatterypack. Frequencies
andfeatures are enteredvia the
keypadon the front of the unit.The
keypadanddisplay may be illumina-
tedfor night use. Power On/Off,
volume, squelch sensitivity,keyboard
lockout, and transmitter lockout
controlsare locatedon the top of the
unit. Jacks for headphone and
microphone are also locatedonthe
top of the unit. The flexibleantenna
may also be removed
so the unit may
be usedwith an external antenna.
License Requirements
If the KX 99 Transceiveris to be
utilizedinan aircraftan Aircraft Radio
StationLicenseis required.
If the
transceiveris to be usedas a ground
station, then a GroundStation
Authorizationis required. Included
with the KX
99 are a FCC Form 404,
Application for Aircraft RadioStation
License anda FCC Form406,
Application for GroundStation
Authorizationinthe Aviation Services.
Additionalcopiesmay be obtainfrom
your nearestFCC FieldOffice.
This equipment hasbeen
acceptedby the FCC and enteredon
their listof Type Accepted Equipment
as King Radio CorporationModel
KX 99, (ASY7BLKX 99).
Caution: The VHF transmitter in this
equipment is guaranteed to meet
FCCacceptanceover the operating
femperaturerange only whena King
crystal is used in the stabilizedmaster
oscillator. Use of other than
a King
crystal is consideredan unauthorized
modification,and will void the
warranty.

Antenna Requirements
The flexible antenna that is
includedwiththe KX 99 isvery
convenientand may be usedfor both
communicationsand navigation
purposes. However a moreefficient
antenna may be requiredfor some
applications. For maximum utilization
of the
KX 99 insidean aircraft,
automobileor other metalenclosure,
an externalCOMM antennashould be
used for communicationsand an
externalNAV antenna should be used
for navigation.An externalcommuni-
cationsantennawill noticeably
improvethe receptionandtransmis-
sion of communicationradiosignals;
however,it is not recommendedfor
receivingnavigationsignals.The use
of a horizontaltype navigation
antennawill improvethe reception
andthe directionalcharacteristics
of
the navigationsignal but it isnot
recommendedfor communications
transmissionsfrom the KX 99. The
BNCtype connector,locatedonthe
top
of the unit, isstandardfor useon
aircraftradios and antennas
so little
difficultyshould beencounteredwhen
connecting to an existingaircraft
communicationsor navigationan-
tenna.
VOR navigationsignalsare
receivedbestby a horizontalantenna
while communications signals are
receivedbestby a verticalantenna.
This isa good pointto keep inmind
when trying
to receiveweak signals.
When usingthe flexibleantenna inthe
cockpit
or an automobile, try to place
the antenna inthe center of awindow
which isfacingthe stationyou are
trying
to receive.Remember, if the
receivedstationisweak and noisy,
that stationisnotlikelyto hear your
transmission.Obtainthe best received
signal beforeattemptingto callthe
station.
When the KX 99 is
to be used as
an emergency backupComm or Nav
radioinan aircraft,one
or two antenna
adapters (P/N 071 -01443-0001) may
be installed
to easily connectthe
KX 99 to the existingaircraftantennas.
See diagram below.

Nickel Cadmium (NiCad)
Battery Pack
The standard power source
suppliedwith the
KX 99 is a 9.6 volt,
720 mA hour, rechargeable nickel-
cadmium batterypack. The battery
that isshippedwith the
KX 99 will not
befully charged andshouldbe
charged prior
to use.
If possible, the battery shouldbe
fully dischargedbeforerecharging.
This will maintainthe maximum useful
charge inthe batteryandavoid
"memory"problemsassociatedwith
thistype battery.
A characteristicof
NiCadbatteriesisthat they do not
holdtheir chargefor longperiodsof
time such as an alkalinebatterydoes.
Caution:
Do notstore a dischargedbattery
pack. Battery cellpolarity may
reverse making it impossiblefor the
battery
to fullyrecharge.
Do not storea battery pack whereit
might be accidentallyshorted. The
current capabilityis tremendous.
Do not crushor disassemblea
NiCad battery pack. Thereare toxic
chemicals inside.
Do not disposeof thebatterypack
in a fire. It may explode.
Do not exceed the recommended
quick charge current.Useonly the
approved chargers.
The KX 99 comes standardwith
atricklecharger capable
of operating
on either 11 5V or 230V. To charge
the battery; plugthe charger module
intoan appropriate wall outletand
plugthe other endintothe connector
marked"CHRGwhichislocatedon
top of the
KX 99. It takes approxi-
mately
12 hours to fully charge the
NiCadbatterypack.
Caution: Toavoidpossible damage
to theKX 99 make absolutelycertain
that the
7 15V/230V selectswitch
located
on thetricklechargeris in the
correctposition for the voltage
to be
used.
The amount of time that the
NiCadbatterypack will power the
KX 99 on one chargedependson a
number of factors:
The dutycycle (amount
of timethe
unit istransmittingversustime
receiving
a signalversus squelched
standby operation).Transmitting
dischargesthe batteryfastest.
The volume levelof the received
signal.
The temperature.
A colder battery
will not last as long.

Alkaline Battery Pack
An optionalreplaceablecell
alkalinebatterypackis availablefor
the KX 99. Alkaline batteriesare used
for radiosthat are maintainedfor
emergency purposesbecausethey
have extremely longshelf lifeand no
maintenanceis required.
ALKALINE
BATTERY PACKSARE NOT TO
BE
RECHARGED!

The alkaline battery pack holds 8
'AA" sizecells. To gain access to the
8 cells,first removethe batterypack
from the KX 99 (seebelow).Next,
with one handholdingthe outsideof
the batterypackcase, usethe other
hand
to pressdown firmly on the
centerhubon the top of the case.
The batterycell holderwill slide out
the bottomof the case.
Alkaline batterylifewill be
approximatelythe same as that
of a
NiCadfor a 90% STBY, 5% REC and
5% TX duty cycle. However, alkaline
battterylife will beconsiderablyless
than a NiCadat higher duty cycles
and considerablygreaterthan a
NiCadat lowerdutycycles.
Battery Pack Installationand
Removal
To installthe batterypack (either
NiCador alkaline), locatethe center
hub onthe top of the batterypack into
the recessonthe bottomof the unit.
Positionthe batterypackat a
30"
offset so that the two metalstudson
the battery packgo intotheir respec-
tive recesseson the bottom
of the
unit. Apply upwardpressure
to the
pack while twistingthe pack
so that
it's sides are flush with the sides of
the unit. The metal tab on the side of
the unitwill lock the packinto position.
To removethe battery,turnthe
radio off. Press uponthe metaltab on
the sideof the unitwhile twistingthe
batterypack
30" and remove it from
the radio. See figure below.
Low BatteryIndicator
The KX 99 hasa low battery
indicator"beep" tone that
will signal
the user when the battery
is almost
unusable.
HeadphonelMicrophoneAdapter
Externalheadphone and
microphonejacks are locatedontop
of the
KX 99. The suppliedhead-
phone/microphoneadapter allows
standardaircraftheadphonesand
microphones
to be usedwith the
KX 99. The clipon the adapter should
beconnected
to the protrudingattach
point
on the rightsideof the unitto
providestrain relief.
If a headset with
a boommikeis used, the transmit key
buttonon the side of the KX 99 may
be used
to key the transmitter.A
separate push-to-talkswitch may also
be usedwith the headphonelmicro-
phoneadapter.
