4.3 Connecting and Installation
Read this manual before using your VT310 and check if all parts are included in the packaging box.
Ensure that your VT310 has a working SIM installed.
- Check that the SIM has not run out of credit (test the SIM in a phone to make sure it can send and
receive SMS)
- Check that the SIM Lock code is turned off
- If you require the function of sending an SMS location report to the authorized phone number when it
makes a call to the VT310, please make sure the SIM installed supports displaying caller ID.
Before inserting SIM card, cut off the power for the AVL unit.
Install SIM Card
- Unscrew and remove the front cover of your VT310.
- Insert the SIM card by sliding it into the card slot with the chip module facing to the connectors on PCB.
- Put back the front cover and screw it up.
Connect the GSM Antenna to the unit.
Connect the GPS Antenna to the unit.
- GPS antenna is used to receive satellite signals in the sky. It should be fixed to face the sky and should
not be covered or shielded by any objects containing metal, such as the metallic windshield.
Find a suitable place inside the car for installing the unit. Wiring connections must be fi rm and reliable
and the joints should be wrapped with insulating tape tightly. The unused electrical wire should be
properly insulated.
Check if all wirings have been connected correctly and then connect the unit to
the motor power.
A connector for microphone is set in the PCB. If you need to link with an extra microphone for wiretapping
