Check if there is vehicle power supplying to the
power cable correctly, then use the voltmeter to
check if there is correct power output more than 9V
from the surge protector.

from it, then the power cable may be damaged and
needs to be replaced.

Cause
Solution
Poor GSM signal reception
1.
Use the cell phone to check if the GSM signal is
weak there. If yes, move the vehicle for better GSM
reception and check again.
2.
Check the GSM antenna connects to the tracker
correctly and securely. Sometimes it is switched with
the GPS antenna connection intentionally.
3.
Check if the GSM antenna is installed at a proper
place to have a clear view of the sky.
4.
Check if the GSM antenna cable is twisted or
damaged. If yes, the GSM antenna needs to be
replaced.
5.
Change the GSM antenna and check again.
Poor internet connectivity
1.
The GSM network is busy. The tracker can’t register
to the GSM network. Press the reset button in the
rear panel of the tracker. Wait for 5 minutes and
check again.
2.
The GPRS connection is not available or the GSM
signal is too weak to open a GPRS connection.
Press the reset button in the rear panel of the
tracker. Wait for 5 minutes and check again.
3.
The SIM card is invalid or blocked. Change a valid
SIM card (from the same provider) and check again.
