4. Device Installation
4.1 Install device
4.1.1 Please ensure the device is installed by an auto electrician otherwise you may
void your warranty if wired incorrectly resulting in damage to the device.
4.1.2 Installation Notice
•Hide device properly inside the car body to avoid damages and security
from potential thieves.
•Keep away from RF emission sources such as backing radar, car burglar
alarm and other vehicle mounted communication devices such as UHF and
car phones.
•Device is best mounted under the dash and the AM/FM radio can be used
as a source of fused power (+12vDC/-12vDC/Ignition Accessories +12vDC).
•Always connect to a fused power source such as suggested above. Never
connect directly to a power source that is not fused as it could result in fire.
•Suggest using wide double-sided adhesive to fix into place or use cable ties
and other liable methods to fix.
•Please ensure the built in GSM/WCDMA/LTE antenna and GPS antenna is
facing up (Towards the sky) when installing, without any metal material
covering the top as this could weaken the signal and cause the device to not
work properly.
•Temperature sensor (Refrigerated Logistics) should be placed in the space
that needs to be detected.
4.2 Device Wiring Definition
Fuel Pump

10
4.2.1 Power Cables and Interface
The standard input voltage of the device is 9V-72VDC, using the supplied wiring
harness, the Red wire needs to be connected to positive and the Black wire
needs to be connected to negative/ground.
Please connect the negative wire separately to ground and not to not to any
other ground.
Connect the ACC wire (Orange wire) to the ACC switch of the vehicle, this will
enable the device to get the ignition status of the vehicle. If not using the ACC
feature, secure the Orange wire using cable ties and make sure the end is not
exposed where it can short on something.
Connect the #4 wire (Yellow wire) to the relay. Use cable ties to fix the relay to
waterproof place. If not using the relay, secure the yellow wire using cable ties
and make sure the end is not exposed where it can short on something.
Connect SOS Button / External Battery / iButton to PIN 7 & PIN 8.

4.3 Relay Wiring
Relay wiring diagram shows how to wire the relay to control the fuel pump.
4.3.1 Connect the 86 port to the positive pole of the vehicle power (+12V / +24V).
Connect the 85 port to the #4 wire (Yellow wire) of the device.
4.3.2 Remove the positive pole of the fuel pump and connect to the 87a pole of the
relay and connect another wire from pole 30 of the relay to the fuel pump
where you removed the positive wire.

9. Trouble shooting
9.1 Device is not connected to platform
Device is never online on the position server when installed for the first time. Please
check device:
1) Are power cables wired correctly? Pay attention to not connect them to
controlling cables of vehicle.
2) Is SIM card installed correctly? Please refer to the installation instructions.
3) Check the status of LED indicators. If device is okay, the red LED and blue LED will
intermittently flicker.
4) Inquire parameters of device via SMS commands and check replied parameters.
9.2 Offline status
First check if LED indicators are okay, if cannot check them, you can check SIM card
following next steps:
1) Call SIM card of device and check if you can hear connecting ring.
2) Check if vehicle is in the area where there is no GSM/WCDMA/LTE signal.
3) Check if one device or all devices are offline in the area. If all devices are offline,
you should ask operator if network is okay.
4) Check if SIM card has enough balance/credit.
5) If device becomes offline on the last day of one month, please check GPRS is
closed or not.
6) Inquire parameters of device via SMS commands and check replied parameters.
9.3 No GPS Positioning
If the GPS is active, but the device position has not been updated for a while, please
check device:
1) If the vehicle is in a place where these is no GPS signal. IE. Tunnel.
2) Has the device been installed with the top of the device facing towards the sky?
3) The GSM/WCDMA/LTE and GPS signal may be weakened if the device is installed
in a place with electromagnetic wave absorption material (such as metal blocks).
Special attention should be paid if there is metal thermal insulation layer or
heating layer on the front windshield. If so, the position accuracy will decline, and
the severe ones will not be positioned.

Serious position drift will be found in places where GPS signal is poor. Please move
the vehicle to an open area.
