applications.It hasmultiple I/O interfacesthatcan beused formonitoring orcontrollingexternal
devices. Its built‐in GPS receiver has superior sensitivity and fast time to first fix. Its triple band
WCDMAsubsystemsupportsUMTS/HSDPA850(BandV)/1900(BandII)/2100(BandI)MHzandquad
bandGSM/GPRS850/900/1800/1900MHz,allowingtheGV75W'slocationtobemonitoredinreal
timeorperiodicallytrackedbyabackendserverandmobiledevices.Itsbuilt‐in3‐axisaccelerometer
allows motion detection and extends battery life through sophisticated power management
algorithms.Systemintegrationisstraightforwardascompletedocumentationisprovidedforthefull

The method to power on GV75W:Useexternalpowertoturnon.
Whentheexternalpowerisremoved,GV75Wwillswitchtointernal backupbattery andkeep on
running.Wheninternalbackupbatteryisexhausted,GV75Wwillreportamessageandthenturnoff. 


3.3. PowerConnection
Theredwireispowerwireandtheblackwireisgroundwire.Theinputvoltagerangeforthisdevice
isfrom8Vto32V.Thedeviceisdesignedtobeinstalledinvehicles that operate on 12V or 24V

The white wire is used for ignition detection. It is strongly recommended to connect this wire to
ignitionkeyat“RUN”positionasshownabove.
Analternativetoconnectingtotheignitionswitchistofindanon‐permanentpowersource(likethe
