3GETTING STARTED
3.1 Insert SIM card, battery, attach a neck strap
All SIM cards must be kept in a safe place. You may request your SIM card supplier to provide SIM
cards and information about the use of SIM card related services. The supplier may be a service
supplier, a network operator or another seller. How to insert the SIM card is shown below. A standard
sized SIM is required.
Note!
Before removing the cover, switch off the device and disconnect it from the charger or PC. The device must be
always kept and used with a cover and the screw screwed tightly

EziTRAK®GH3000 User Manual
version 1.0 Page 7
If an unsuitable SIM card has been inserted or the device fails to detect it, the device will restart
automatically and will try to make the connection again (if the SIM card is not inserted then the device
will restart three times). If the connection fails, the device will indicate it. If the card has been inserted
later, the device must be switched off and switched on again or has to be restarted manually.
3.2 Charging the battery
Connect the USB wall charger to the device via USB cable and plug the charger in to the alternating
current wall socket. We recommend charging the device using a 220V USB wall charger when
charging the device for the very first time (not charge it via PC).
If the device is working very intensively (GPS data logging period is very short, GPS data sending via
GPRS is enabled, or GSM signal level is very low and device is constantly searching for GSM
operator) then the battery charge time can be much longer then usual. The maximum battery charge
time is 9 hours. To charge the battery faster we recommend charging the device when it is switched
off. In order to prevent the device from turning on automatically when it is connected, you have to
change its configuration using the SMS command. Battery charge time when the device is switched
off is approximately 4 hours.
Note!
If the battery is fully discharged, the device will not indicate about charging for approximately 10 min. If the
battery level is very low during charging, some of the functions of the device might be limited for a couple of
hours until the battery reaches the required charge level.
Note!
Only approved batteries, chargers and accessories supplied by EziTrak® should be used with this device. By
using other sorts of batteries, chargers and supplements you risk to be deprived of all guaranties and it also
may be dangerous for you and your environment.
Note!
GH3000 should be fully charged (100%). If charged not fully (less than 95%) indication of the battery discharge
level can be not accurate.

will not find its location.
Step 3
Read received SMS message and find the text Fix: <numbers>.
These numbers are your device location coordinates. If instead of
numbers there is N/A, that means the device could not find its location.
Step 4
Open the free map access via your browser. Enter the FIX: numbers into the Longitude and Latitude
fields and click Locate. Your units position should be pinpointed on the map. If you have installed
Google Earth software open it and on the left side of the window find the field fly to. In this field enter
the coordinates you got from the device and press the button Begin search. If you use maps on your
browser just type the coordinates into the search field and press the search button. After few seconds

8ALARM FUNCTION
Alarm function - sends alarm data via GPRS, calls or sends special warning SMS messages to one or
more set phone numbers. When the Alarm function is activated the device starts searching its location
all the time. Being in this mode, device is trying to get the most accurate track. That is why alarm
mode draws the most power.
8.1 Alarm function activation
Alarm function can be activated by pressing button (4) (See Chapter 4 - Getting to know the device)
or automatically by events, depending on the configuration and parameters used.
8.2 Alarm configuration
To configure Alarm warning you need to know three basic alarm warning methods: SMS, cycle call,
GPRS or SMS. The simplest Alarm configuration can be set via quick configuration SMS messages.
All the alarm methods have their own parameters, but there are a few basic parameters that are
required for all methods.
8.2.1 Basic parameters
Alarm duration time - the device working time after activation of the alarm mode, Alarm track logging
period - period, how often the device will write the coordinates in the memory, Pre-alarm time - the
time until the alarm will be activated.
8.2.2 Cycle call method
To configure this alarm method you need to create a phone number list.
No answer time - when alarm is active, device will call to the first number in the list. If this number is
busy or did not answer after this time limit is reached, device will terminate this call and start calling to
the next phone number on the list.
Conversation time and conversation overtime - if the call will be answered device starts counting

until GPRS starts working again.
8.2.4 SMS method
Similar as in the GPRS or SMS method you need to configure data logging period, alarm duration
time, SMS messages sending period and create a phone number list.

15 A-GPS FUNCTION
Assisted GPS, generally abbreviated as A-GPS, enhances the start-up performance of a GPS
satellite-based positioning system under poor GPS visibility conditions (when only 2 satellites are
visible). In all other cases A-GSP may lead to additional GPRS-traffic costs and processing time due
to the A-GPS file download and handling. For more information please visit:

16 LOW BATTERY LEVEL NOTIFICATION MESSAGES
The device monitors the battery charge level all the time and when the charge level becomes less
than set, you will be notified about it by an SMS message. There is a possibility to be informed when
the battery fully charges and the device is ready to be used.
16.1 Function configuration
You can choose a couple modes of configuration: the device does not send any notification about
battery charge level or the device sends a notification when the battery discharges to a set value or
the device discharges to a set value and is charged fully. A very important parameter is the phone
number to which the device will send SMS messages about battery charge level. This number can be
configured using quick configuration messages. When changing the parameters of the discharging
battery indication, take notice what you are changing – the battery charge level notification by SMS or
by LED indication. These are separate parameters and can work separately with different configured
charge levels.
Note!
Please have in mind that the battery charge level measurement can have an error of ±5-10%. This error
depends on the state and quality of the battery.
17 SIM PIN CODE
If an unsuitable SIM card has been inserted or the device fails to detect it, the device restarts
automatically and tries to start the connection again (if the SIM card is not inserted the device restarts
three times). If a SIM card with an activated PIN Code has been inserted into the device, it will not be
able to connect to the GSM network and perform certain functions. Therefore, if you want the device
to be fully operational, the PIN code must be removed using a mobile phone, if available.
Note!
Please pay attention, if the GSM indicator is blinking red, the PIN code maybe enabled on your SIM card.
Ensure the pin is disabled before inserting it into the unit.

an auto Geo-Fence where an invisible 200m zone is created around the unit. After it moves out of the
safety zone the device starts the configured alarm mode.
21.1 Parking configuration
Parking function can be configured by configuration SMS messages. Configuring it is important to
configure the fence and alarm configurations. If you want to activate or deactivate the function by
button you will need to set up the keyboard as well.
The basic configuration parameters of this function are:
a) The dimension of the fence which is around the asset has a minimal fence radius of 200 meters.
b) The form of the fence which can be set is a circle only. The device creates the zone after it finds a
fix of its coordinates.
How the function will be activated or deactivated depends on your choice.
21.2 Parking activation/deactivation
Parking function can be activated by SMS or button. Parking function can be enabled in whatever
mode the device is working in, except when the alarm is enabled, there is an active conversation or
an incoming call. When the device receives the command to activate the function it immediately finds
its location and defines the safety zone and activate the alarm when the device leaves this zone. If
there is no possibility to find its location, it will activate the alarm on movement detection.

24 SPECIAL SMS REQUESTS
Special requests – these are special text messages which check the GH3000 device’s status and
provide response via SMS to the requesting person. Example: The requesting person sends an SMS
with the content FIX? The device receives such an SMS message and will send back a status SMS.
FIX? – GH3000 turns on the GPS receiver (if satellites are available), gets its location and sends it (in
case of reception) to the requesting person. If no current coordinates are detected, the device sends
the latest coordinates (date/time) from its internal memory.
Smstrack on is a special request message which activates the SMS tracking function. To turn off
this function use an SMS message with the text Smstrack off.
If the device receives a request with the text Geo? it finds its location and checks if it is in a set
geofence zone and sends an SMS message with the information about these zones.
ALARM: OFF – GH3000 will disable the ALARM.
When the alarm method is set to Call, the device calls to all phone numbers in the list and saves its
location until the Alarm duration time is reached. The message Terminate will stop the calling
process, but will not stop the alarm.
INF? – GH3000 will send information about its status.
TRACK? – GH3000 will send all collected records from internal memory to the Server (via GPRS).
