Test Description
Audioloopbacktest
Routesaudiofromanexternalaccessorymicrophonetotheradio'sinternalspeaker.
Beforerunningthistest,turnthevolumedowntolimitinterferenceandreducethe
impactofaudioartefacts.
Displayfreq
Displaysthetransmitandreceivefrequenciesofthecurrentchannel.Alsodisplays
thechannelstatus(CNV,TCH,CCH
1
)andthemode(ANA,PH1orPH2
2
).Ifthe
radioisscanning,thisinformationmaynotbeavailable.
Displaytest
Displaysatestscreenofallcolorsthatappearonthescreen.Usefulforidentifying
deadpixels.
GPSNMEAdata
Displaysthelastrawdatareceivedfromtheradio’sinternalGPS.Theradiowilldis-
playallsupportedsentenceformatsreceived(forexample$GPRMCand$GPGGA
sentences).Notethatthedisplaywillnotautomaticallyrefreshwhennewdatais
received.
Keypadtest
Soundsanaudibletonewhenakeyispressedorreleasedontheradio,orthe16-way
and3-wayselectorsaremoved.Theradioalsodisplaysthekeyorselectorname
alongwith“pressed”or“released”orthenewselectorposition.
QoS(P25channelsonly)
Displaysinformationaboutthequalityofservice(receivedsignalstrength(RSSI)
withanindicationofdigitalvoicequality).Alsodisplaysthechannelstatus(CNV,
TCH,CCH
1
)andthemode(PH1orPH2
1
).
RSSI Displaysthereceivedsignalstrength(RSSI)ofthecurrentchannel.
RxTone
Receivesa1011Hzor1031Hztoneanddisplaysthereceivedsignalstrength(RSSI)
andthebiterrorrate(BER)ofthereceivedsignal.Alsodisplaysthechannelstatus
(CNV,TCH,CCH
1
)andthemode(PH1orPH2
1
).OnaP25conventionalchannel,
theusercanselectwhethertoreceivea1011Hz(Phase1)or1031Hz(Phase2)tone.
OnaP25trunkedchannel,thenetworkselectswhether1011Hzor1031Hzisused.
Sitedisplay
Showsthechannelnumber,signalstrengthandsystem-identitycode(SYSCODE)
forthecurrentlyregisteredtrunkedsite.
Sitemeasure
Liststhecurrenttrunkedsite(indicatedwithanasterisk)anduptosixdetectedadja-
centsites,withreceivedsignalstrength(RSSI)information.
Tonetest Generatesanaudibletoneforthedurationofthetest.
TxTone Transmitsatoneof1011Hzor1031HzonthecurrentP25channel.
TxToneCal
Transmitsa1011Hzor1031Hztoneonthecurrentchannelwithabiterrorrate(BER)
of5%.
Txpowertest
Displayshardware-relatedinformationwhiletheradioistransmitting.Information
includesthefinalPAcurrent(inmA).
