“Gokit”MobileUnitSetup

Parkyourvehicleinanareawithanunobstructedviewofthesouthwesternsky.(Thisismandatoryfor
obtainingaconnectionwiththesatellite.)Itispreferabletoavoidallobstructionswithinthree(3)
metersoftheantenna;obstructionslessthansix(6)inchesindiametercanbeignoredbeyondthis
distance.Itisrecommendedthattheantennabeplacedasfarawayaspossiblefromanyotherantennas
ordevicesemittingradiofrequency(R/F)signals.
Openthego‐kit.Removetheantennabygrabbingitnearoneofthethreemagnetsandpulling;when
oneofthemagnetsisloose,theothersareeasiertoremove.(Note:Themagnetsarepowerfulandwill
provideresistance.)
Placetheantennaontheroofofthevehicle,orientedsothattheantenna’scableoutletisfacingyou.It
isimportanttomakesuretheantennaisplacedonalevel,firmmetalsurface.Themagnetsarevery
powerful;becarefulnottogetyourfingerspinchedbetweentheantennaandthemountingsurfaceas
themagnetsattachtothesurface.



Removethe12V“cigarettelighter”adaptercable.Inserttheappropriateendofthecableintothego‐
kit,makingsuretoplugthecableintotheoutletlabeledInput12VDC;connecttheoppositeendintothe
vehicle’s12Vreceptacle.(NOTE:Dependingonyourvehicle,yourvehiclemayneedtobeturnedonto
providepowertothe12Vreceptacle).Connectthehandsettothego‐kit.Connecttheantennatothe
go‐kitwiththecoaxialcable;screwoneendontotheantennaandtheotherendintothego‐kit.Power
onthego‐kit,


Ifthehandsetdoesnotpoweronwhenthedesktopunitisswitchedon,pressthehandset’spower
button,locatedontheupperleftcornerofthehandset;releasethepowerbuttonwhenthe“MSAT”
logoappearsonthedisplay.Thehandsetdisplaywillilluminatetoindicatethatitisactive.

Oncethehandsetisactivatedandlockedontothesatellite,anLCDdisplaysimilartotheimagebelow
shouldappear.“B1”indicatesthattheMSAT‐G2islockedontoLightSquared’sbeam#1overtheEast
Coast(see“NetworkCoverage”section,below,formoredetails).“S99”indicatestheMSAT‐G2hasa
signalstrengthof99outofapossible99withtheLightSquaredsatellite.


Youshouldnowbereadytomakeacall.

Push‐to‐Talk(PTT)
SelectingaTalkgroup
“DispatchRadio,”or“Push‐to‐Talk”(PTT)modeisthedefaultmodeforthehandset.(The“DR”inthe
upperrightcornerofthehandsetdisplayindicatesthismode.)TousePTTmode,pickupthehandset
andselecta“talkgroup.”(Note:Ifthehandsetiscurrentlysettothetalkgroupyouwant,skipthisstep.)
Anormaltalkgroupcanbeselectedasfollows:
•PresstheGROUPsoftkey(i.e.,therightside“Minus”signkey)onthehandsetandscroll
throughthetalkgroupswiththeup/downarrowkeysuntilthedesiredtalkgroupisilluminated.
•PresstheGROUPsoftkeyagaintoselectthedesiredtalkgroup.
Aprivatetalkgroupforone‐to‐onepush‐to‐talkoperationcanbeselectedasfollows:
•PresstheGROUPsoftkey(i.e.,therightside“Minus”signkey)onthehandsetandscrolltothe
PrivateModetalkgroup(tag00)usingtheup/downarrowkeys.
•PresstheGROUPsoftkeyagaintoSELECTtalkgroup00,anda“?”willappearonthedisplay
screen.Enterthefour‐digitDirectoryNumber(DN)oftheradioyouwanttocall.
Note:ToquicklychangetheDNwhiletheradioisidle,pressthe#keytoclearapreviouslyusedDN.
YouwillbepromptedtoenteranewDN.

MakingaPTTCall
Onceyouhaveselectedatalkgroup,youcanmakeaPTTcallbypressingandholdingthelargePTT
buttonontheleftsideofthehandset.“CALLING”willappearonthehandset. Whenthetalkgroupyou
arecallingisconnected,youwillhearadoubletone,andthescreenwillchangefrom“CALLING”to
“USERON.”





YoumustcontinuetopressthePTTbuttontotransmityourvoice.Onceyouarefinishedspeaking,
releasethePTTbuttontoallowotherstospeak.Thehandsetwillthendisplay“VACANT.”Whenthereis
nocurrentuserholdingthePTTbutton,“VACANT”willbedisplayedonyourhandsetaswellasallother
handsetsparticipatinginthePTT.Ifthetalkgroupremainsvacantformorethan10seconds,the
talkgroupwillbedroppedfromthenetwork.



6

WhenanotheruserbecomestheactivespeakerbypressingandholdingthePTTbutton,thatuser’s
directorynumber(DN)willbedisplayedonyourhandset.OncethatuserreleasesthePTTbutton,
“Vacant”willonceagainbedisplayedonthehandset.

Priority1Interrupt
Priority1Interruptisapush‐to‐talkfeaturethatallowsausertodotwothings:
1. Priority1Interruptallowstheuser“hands‐free”push‐to‐talk(i.e.,abilitytotransmitwithout
holdingthePTTbutton)forupto30seconds.Itcanbeprogrammedtooperateonthe
talkgrouptowhichtheradioistunedoritcanbeprogrammedtobringanothertalkgroupupon
theairforanemergencybroadcast,hands‐freeforupto30seconds.
2. Priority1Interruptcanbeengagedtotakethetalkgroupawayfromauseroroverridea“hot
mike”fromanotherradiothathasbeenaccidentallykeyed.Inthiscase,allusersonthe
talkgroupwillhearabroadcastinterruption.
ToinitiatetheP1Interrupt,pressthe“P1”buttonlocatedbetweenthe“Power”andthe“PTT”button
ontheleftsideofthehandset.Theuserwillsee“CALLING”appearonthedisplayscreenfollowedby
“USERON.”Atthistime,theP1buttoncanbereleased,andtheusercanspeakfor30secondswithout
depressinganybuttons.The30‐secondtimercanbecanceledbypressingandreleasingthelargerPTT
button.


MonitorCodes
WhentheMSAT‐G2isidleinPTTmode,itcanbeprogrammedtoselectivelyscantheunit’s
programmedtalkgoups.Iftheunitisactivelyengagedonatalkgroup,scanningisdisengagedandwill
notinterruptthattalkgroup.Theradiomustbeat“rest”forscanningtooccur.Ascanningcode
(LightSquaredcallsita“monitorcode”)willpulltheradiooffthetalkgrouptowhichitistunedforas
longasthescannedtalkgroupremainsupandontheair.Oncethetalkgroupdropsoff,theradioreverts
tothetalkgrouponwhichitwassitting(tuned),andscanningresumes.Thesescanningcodescannotbe
userprogrammed.Theymustbedownloadedtotheradiofromthesatellitenetwork.Alltalkgoupsare
downloadedwithamonitorcode;thiscodedetermineswhetheratalkgoup’sradiotrafficwillbepicked
upbytheMSAT‐G2’sscanfunction.
•MonitorCode“0”(LOW):LightSquareddownloadsalltalkgroupswithMonitorCode“0”
unlessotherwiserequested.AnytalkgroupwithMonitorCode”0”assignedtoitwillonly
hearthattalkgroupwhentheradioistunedtothattalkgroup.
•MonitorCode“1”(MEDIUM)andMonitorCode“3”(HIGH):BothoftheseMonitorCode
levelswillprompttheradiotoconstantlyscanwhileatrestforanytalkgroupswiththese
MonitorCodesassignedtothem.Whicheverscannedtalkgroupcomesupontheairfirst
willengagetheradio,disableanyfurtherscanning,andkeeptheradioengagedonthat
talkgroupuntilthetalkgroupdropsoffthenetwork,atwhichtimescanningwillcontinue.
ThedifferencebetweenMonitorCodes“1”and“3”isthatscanningofanytalkgroupwith
MonitorCode“1”canbedisabledatthehandset;scanningforanytalkgroupwithMonitor
Code“3”cannotbedisabled.
