6.1.2 Connect the wires with the original car circuit as shown below:
(When the ACC is connected to your vehicle’s ignition, the GPS-303 will know if your
ignition is ON or OFFdepending on the voltage)
6.2 SIM CARD Installation
Use the screwdriver included with the device to open bottom cover and insert
the SIM card to the designated sim card slot. Do not forget to activate your sim
card by making a quick call if you are using a pay as you go sim card. If you
would like to use GPRS/Internet tracking, make sure your sim card's internet
tracking is enabled.
Ensure your phone has the "show caller id" option enabled, otherwise you
will not get any response from your tracker.
6.3 Turning the GPS-303 “on”
Connect the positive & negative wire, red & black ones, with 12V or 24V car
power system, wait for 1 minute after connecting power to and move the backup
battery switch to "on" position. (The switch is located next to the sim card slot
inside the casing)

6.4 GSM/GPS LED Indicator
Red LED: LED ON = Charging
LED OFF = Fully charged
FAST flashing fast = Low power
Green LED: LED flashing once a second = GSM mode
LED flashing once every three seconds = GPRS mode
LED constantly ON = No GSM reception
Blue LED: LED flashing = GPS fix established
LED OFF = No GPS reception
6.5 Changing your tracker’s password
Send SMS "password+old password+space+new password" to GPS-303 to
change its password.
Example : password123456 99999
Response: password OK
If you forget your password, you can restore it to the default password using the
command "adminpassword13142324".
Please note that you don't have to change the default password as without your
tracker's sim card phone number, it is not possible to have access to the tracker.
Make sure the new password is in 6 digits.

8
When reading this user manual, you will notice that we have used "+" and
"space" between some words;
"+" between two words means they should be written together as one word and
"space" between two words means you should leave one character space
between two words.
e.g. : sleep+123456+space+shock this should be sent to the tracker as
follows;
sleep123456 shock
6.6 Authorization
You have to save your phone number as authorized user to be able to use certain
functions as movement alerts, sos alerts and reports. You can authorize up to 5
numbers. Authorization can be done in two different ways;
6.6.1 Dial the GPS-303’s number 10 times from your mobile phone and it will
register your mobile phone number as the authorized number automatically
6.6.2 Send SMS “admin+password+space+cell phone number” to set up an
authorized number. All the other authorized numbers must be set by the first
authorized number.
Example: admin123456 07776665554
Response: admin OK
Depending on your network and phone, the tracker may read your number in
internatonal format. If you notice that the GPS-303 doesn’t send you any alarm
notifications after or doesn’t respond to your calls with a location report after

9
setting yourself as the authorized number, try authorizing your number in
international format;
Example: admin123456 [phone]
Response: admin OK
6.6.3 Delete authorization Send SMS：“noadmin+password+space+authorized
number” to delete the authorized number.
6.7 SMS Text Message locating
If there aren't any authorized numbers set-up, GPS-303 will reply to all calls
with a location report. If there are authorized numbers set-up, only authorized
numbers will be able to receive location report from the tracker.
The SMS text message will include coordinates, current speed, time and date. It
will also contain a direct Google Map link for smartphone users.
*If you request your tracker's location and receive blank text message with no
coordinates or location information, this means your tracker has not established a gps
fix yet. Once it establishes a gps fix it will send another text message with the new
coordinates.
6.8 Interval Tracking
GPS-303 can send automatic location reports at set intervals. If SMS mode is
active, reports will be sent as SMS text messages. If GPRS tracking mode is
active, location report updates will be uploaded to the online tracking server.

10
6.8.1 Continuous interval tracking:
Send SMS “fix030s***n+password” to the GPS-303, it will reply the
latitude & longitude continuously at 30 seconds fixed intervals.
Note: Minimum interval setting is 10s.
Example: fix030s***n123456
Please note that you will not get a response for this message.
6.8.2 Smart interval tracking:
Please activate "Continuous interval tracking" before selecting this function.
Send sms command "distance+password+space+distance" to activate smart
interval tracking. GPS-303 will reply "Distance ok" and it will start uploading
its location at pre selected time intervals and distance.
Example: distance123456 0050
Response: distance OK
This means that distance is 50 meters; the number must be 4 digits. This will
configure the GPS-303 to send its location every 50 meters.
To set this function on live tracking mode: Set time interval first and then
distance interval, GPS-303 will locate upon the time and distance.
6.8.3 To Cancel auto-tracking: Send SMS “nofix+password” to the tracker
device to
cancel the auto-tracking (auto-reporting).
Example: nofix123456

11
6.9 Smart angle updating
The tracker will update the positions automatically to web server once the
vehicle changes driving direction over a pre set angle value. This function is
only available in GPRS mode.
Send sms command "angle+password+space+angle" to activate.
Example: angle123456 45
Response: angle ok
The angle must be 3 digits, default angle value is 30 degree.
6.10 GPS drift suppression
GPS signal can be affected with many factors like weather and location.
Surrounding buildings or trees can reduce GPS signal strength. Clouds also
degrade the signal and the locating accuracy may drop, causing your GPS-303
to show up in different locations in a 50 meter radius time to time. If you are
using live (GPRS) tracking you may notice your GPS-303 doing 20-50meter
jumps on your map when the vehicle is actually stationary. GPS drift
suppression is used to avoid this. When activated, GPS-303 will stop sending
GPRS data to live tracking server when the ignition is OFF. GPRS drift
suppression also helps with sim card economy as the GPRS mobile data will
only be used while the vehicle is moving.
This function is switched "OFF" by default. Send "suppress+password" to
GPS-303 to activate, it will reply" suppress drift ok". The GPS data will stop
updating if the vehicle is stationary. GPS data will update automatically once

12
vehicle starts moving. Please note that the ACC (ignition) detection wire (white)
on your tracker should be connected for this function to work.
Example: suppress123456
Response: suppress ok
To cancel: send "nosuppress+password" to the GPS-303
Example : nosuppress123456
Response: No suppress ok
6.11 Exact street address by SMS
You must set the APN of your GSM network provider for the SIM card used in
GPS-303 before using this function. If your local GSM network requires user
name and password for GPRS, please set it up according to the GPRS
instructions in chapter 6.27. Send SMS “address+password” to GPS-303 after
APN has been set up and it will reply in exact address including street name.
Example: address123456
Response: 20a Park street, clifton, bristol, bs1 5ja
6.12 Cell-ID tracking (LBS)
If GPS-303 is unable to establish a solid GPS fix, it will calculate its location
using Cell-id info. Location reports will include the GPS coordinates of the
last known position as well as a LAC code. Entering the LAC code to the
"Manual Track" menu of the web tracking platform will enable you to see the
tracker's current location. You can also send command "address+password" to

13
the tracker to request exact address. GPS-303 will automatically switch to
tracking by LBS in GPRS mode. Accuracy of LBS (also known as Cell-id
tracking) depends on the distance to the nearest GSM Network Cell Tower or
Base Station. In urban areas this accuracy varies between 25-100 meters.
6.13. Voice Surveillance
GPS-303 is in Tracking mode by default. When voice surveillance mode is
activated, it will automatically answer incoming calls rather than replying with
its location information.
To activate the monitor mode, send SMS "monitor+password" to GPS-303. It
will reply "monitor ok" and switch to "monitor" mode.
Example: monitor123456
Response: monitor OK
Do not forget to switch back to tracker mode once you have finished using the
voice surveillance. When GPS-303 is in monitor mode it will stop updating its
position and it will shut the GPS module "OFF". To change back to tracker
mode use command "tracker+password"
Example: tracker123456
Response: tracker OK
6.14.Data logging
15.1 Auto logging：If GPS-303 loses GSM or GPRS signal, it can store the

14
tracking position and alerts automatically on to the flash drive upon the pre-set
conditions. When GSM signal is acquired, all the event alerts will be auto-sent
to authorized numbers and the live tracking server.
15.2 Logging at preset intervals: Send SMS: “save030s005n+password” to
GPS-303, it will reply “save ok”, and will log the lat, long locations every 30
seconds for 5 times. (S: second, m: minute; h: hour).
Example: save030s005n123456
Response: save ok
15.3 Continuous logging：Send SMS:”save030s***n+password” to GPS-303,
it will reply “save ok”.
Example: save030s***n123456
Response: save ok
15.4 Log Clearance: send SMS: “clear+password” to GPS-303, it will
reply “clear ok”.
Example: clear123456
Response: clear ok
15.5 Logging Volume: Built-in flash 1MB (store about 16,000 positions). This
volume can be expanded by using a Micro SD card which can be inserted into
slot provided. Please refer to section 3.3 to see where micro SD card needs to
be inserted.A 2GB card would be sufficient for up to 10 months.
Data logging function also enables you to use your GPS-303 as a GPS logger.
You can download the location data to your PC by using the free PC software
provided, through USB connection.

15
6.15. Data upload
6.15.1 Auto Upload: If there is no GSM reception, GPS-303 will save all GPS
data to its built-in memory and upload this information to the live tracking
server automatically when the GSM reception is back to normal. This way
tracking data won't get lost while driving through areas with no or low GSM
reception. If you do not wish to use this feature, you can turn it "OFF" by
sending the SMS command "autoload+password+space+off"
Example: autoload123456 off
Response: autoload off OK
6.15.2 Specified date upload：Send SMS: “load+password+space+year month
date” to GPS-303. It will reply: “load ok” and will upload the tracking data of
the specified time/date.
Example: load123456 20110425
Response: load ok
6.16. Forwarding incoming SMS messages
GPS-303 can forward incoming messages from pre-set phone numbers . To
activate this function, send "forward+password+space+third party phone
number" from an authorised phone number. GPS-303 will reply "forward ok",
and start forwarding SMS messages coming from that number. Only one
number can be set-up for SMS forwarding.
Example: forward123456 07776665544
Response: forward ok

16
To cancel SMS forwarding: send SMS command "noforward+password".

at 3 minutes intervals.
Example: move123456 0250
Response: move ok
Note: Setting the radius less than 100 meters may result in false movement alert.

20
The fault alert occurs if GPS position is miscalculated due to bad GPS reception.
Inaccurate GPS reading will cause the GPS-303 to think that it is in a different
location, possibly further from its current location, thus the processor will
accept this as a movement and trigger the movement alarm. However, this may
only occur if the GPS-303 is installed improperly in a place where it can't
receive good signal.
To Cancel: Send SMS “nomove+password” to deactivate the movement alarm.
Example: nomove123456
