TLT-2F GPS/GSM is a car positioning and tracking device based on GPS technology and GSM/GPRS
technology. It receives the latitude and longitude of the user’s location through cell phone messages and then
locates the tracker on Google Map or other digital map software; or positioning data is uploaded by the tracker to
the specified server through GPRS, and the user may search the real-time position and historical track of the
tracker on the internet.
TLT-2F GPS/GSM car tracker applies to motorcycles, electric golf carts and private cars. The product with
built-in antennae integrated is easy to install.
II. Product characteristics
1. Built-in high-performance GPS chipset enables the product to provide accurate positioning in the event of
weak signal and to work normally in urban area , valleys or other sight-limited districts.
2. Built-in GSM/GPRS model supports GSM900/1800MHz (850/1900 MHz), thus it can work throughout the
world.
3. It supports SMS communications or GPRS TCP connection, and receives position information through cell
phone message or used to look into movement track on internet.
4. It provides such functions as SOS, fuel/electricity shut-off, warning by cutting off external power wire,,
geo-fence function, overspeed warning, historical data upload, parking throttle upload and moving vehicle tracking
timing upload.
5. Latest waterproof design IPX 7
6. It has highly reliable electric circuit design and complies with electronic industry standard.

4.1 SIM card installation
a. Select SIM card
●You can use SIM card provided by local mobile operators
●It supports SMS/GPRS function and has enough balance.
b. Open SIM card cover with a screw, and insert SIM card into its groove and lock it, then tighten the card cover
with screws.
Note: 1. If built-in battery is full of power, SIM card inserting will start the product; outside power supply also start
the product without SIM card.
1. Attention should be paid to SIM card installation sequence: firstly insert SIM card and then connect
external power supply. Never reverse the sequence to avoid damage to SIM card.
4.2 Installation of external power wire
General view of external power wire.
Figure 2 Pins from Left to Right
PIN1 (red): 12V power wire of vehicle to connect positive electrode of vehicle battery;
PIN2 (black): ground wire to connect negative electrode of vehicle battery;
PIN3 (green):ACC wire to supply power for carACC;
PIN4 (white): control wire of fuel cutoff/power failure to connect relay;
PIN 5 (yellow): SOS wire to connect ground wire and trigger SOS;
4.3. Relay connection method
The five wires externally connecting TLT-2F are as shown in the following diagram. The red one is 12V
power wire of the vehicle to connect positive electrode of battery. The black one is ground wire to connect
negative electrode of battery. The yellow one is SOS control wire to connect SOS switch and negative
electrode of vehicle battery. The green one supplies power for car ACC and connects vehicle CD and vehicle

radio in parallel. When the car key is put on ACC gear and the green wire detects 12V voltage, the terminal
will automatically start charging function and switch GPRS timing upload mode. The white one is control
wire of fuel cutoff/power failure and connects pin 86 of relay which is a coil end. Pin 85 of the relay which is
another coil end connects fuel channel to supply 12V power (please note working volt of the relay is
consistent with working volt of the product). Pin 30 and Pin 87a are always closed ends and connect fuel
channel power circuit in series. Please install wire in a correct way. Suppliers will not be responsible for
device damage caused by wrong installation.

Chapter Three Initial Use and Model Description
After reading brief introduction to the product, you must know how to install the product. Then it comes to
product’s use.
Firstly, as the user of such product, you need to pre-store telephone number before performing
instruction operation on the device. Telephone number is pre-stored as follows:
Format:*new number 4-20 digits*user password 4 digits *sequence (1-3)**
For example: *13900000000*0000*1**
Description: If TLT-2F receives the instruction and returns confirmation message “SET USER NUMBER
(1-3) OK”, then pre-stored number will be set successfully.
Note: 1. Initial password for the device is 0000.
2. The device can pre-store 3 telephone numbers at most.
3. The instruction also applies to new number which covers existing number. For example, A is the first
pre-stored number. If B also sends instruction to set the first pre-stored number, number of B will substitute number
of A and become the first pre-stored number.
4. Any number not prestored can not be used to dial or connect device end telephone but can send
message instruction.
I. Working mode of device
The product has the following two working modes: SMS mode (message point to point) and GPRS online
mode.
1. If the user only wants to inquire for vehicle position (longitude and latitude) with cell phone, corresponding
address on Google map or control fuel cutoff/power failure with cell phone, please select SMS mode.
2. If the user wants to monitor vehicle real-time status and inquire for its historical track, please select
GPRS real-time online mode.
II. Switchover between the two modes
The following instruction may be used to switch over between the two modes.
Message (SMS) point-to-point mode:
Instruction format: 700+user password (4 digits)
For example: 7000000
Description: When TLT-2F receives the instruction, it will automatically switch to SMS mode. After success,
it will return confirmation message “SET MODE OK, CURRENT MODE: SMS P2P”.
GPRS online working mode:
