⚫ LAC code. Open web platform and find “manual track”, put code received from tracker in LAC and
Cell-ID fields to locate by LBS technology.
Auto track continuously
Trackwith limited times upon timeinterval
Send SMS command “fix030s005n +password” to the tracker device, it will report the latitude & longitude
at intervals of 30 seconds for 5 times. (s:second, m:minute, h:hour). This command set must be in 3 digits

Location based service (LBS) / Cell-ID Locating
If the tracker cannot establish a solid GPS Fix, it will calculate its location using Cell-ID GSM
locating, Location reports will include the GPS coordinates of the last known positions as well as a
LAC code, Entering the LAC code to the “Manual Track” menu of web tracking platform
www.gpstrackerxy.com will enable you to see the tracker’s current location. You can also send
command “address+password” to the tracker to request exact address, track will automatically
switch to tracking by LBS in GPRS mode. Accuracy of LBS depends on the distance to the nearest
GSM Network Cell Tower or Base Station.
Note: This feature can be used normally in most areas according to the signal of GSM network. It m
ay not be available in some areas.

phone number.
Take china mobile for example, mobile users can send “ye” to china mobile number 10086, and
10086 will send user’s balance message to tracker, and then tracker forward the balance message to
mobile phone number , following is an illustration how this function works.
Received and execute
Mobile balance123456 10086 ye Tracker
Send ye out to 10086
10086(China mobile)
Forward balance message to mobile phone
ACC working alarm
Send balance back
Received Balance message Received ye from number in
the tracker and process
This function is deactivated by default. To active this functions, send "ACC+password" to tracker, it
will reply "ACC ok". And tracker will send "ACC on+latitude & longitude" to authorized numbers
when detect ignition on, that means the vehicle has been started; and tracker will send “ACC
off+latitude & longitude" to authorized numbers when ignition off and ACC is off, that means
vehicles has been stopped.
Send "noACC+password" to deactivate this function, tracker will reply "noACC ok"
This configuration can only activate and deactivate the alarm to authorized numbers; it will send to
web platform automatically in GPRS mode and can't be deactivated

And it will remain immobile state until next command to resume.
Stop mode
Execute immediately: Send command “quickstop+password” to tracker, it will reply “quickstop
OK”. Then tracker will stop the car immediately after “stop” command.
Execute depends on speed(Default mode): Send command “noquickstop+password” to tracker, It
will reply “noquickstop OK”, Then the tracker won’t stop the car immediately after “stop” command,
instead, it will reply “it will be executed after speed less than 20KM/H”, and stop the car when the
speed is less than 20KM/H.
Resume the Oil and Power System

13
Send “resume+password" to tracker, it will reply "Resume engine succeed", it means the oil supply is
resumed.
Calibration of fuel sensor
