6. Getting Started
After plucking the Main Connector into the Vehicle Unit, the device
will power up and automatically attempt to register to GSM network.
Provided that your vehicle and the Vehicle Unit’s GPS antenna is
positioned in an area with clear un-obstructed view of the sky, the
device will then start scanning for GPS satellites to obtain its first GPS
lock. This first fix can take several minutes.
To use the communication and vehicle security features of the device,
some mandatory setup parameters need to be configured from the
Control Base software or Tracking Websites before it is able to
operate properly.
After setting up a user account at the Control Base, enter the following
required SIM card details, SMS and GPRS dial-up information and
Contact numbers, before you send them through SMS initialization
command to the Vehicle Unit:
Submit all these information to complete the setup of your Vehicle
Unit. Once the Vehicle Unit initialization command is received, the
alarm siren will sound twice to indicate that the initialization has been
completed successfully.

IMPORTANT NOTE: Once your device has been
initialized, all following commands sent through
the Control Base have to use the same GSM
number (Control Center Number). To switch to a
different Control Center number at a later time,
you will need to send an Initialization command
with the modified Control Center number using
the original GSM number at the Control Base.
