connectors on PCB.
- Put back the front cover and screw it up.
4.4.2 Antenna Connection
Connect the GSM Antenna to MVT400.
Connect the GPS Antenna to MVT400.
- GPS antenna is used to receive satellite signals in the sky. It should be fixed to face
the sky (to be placed under the windscreen is recommended) and should not be
covered or shielded by any objects containing metal.
4.4.3 Find a suitable place inside the car for installing MVT400. Wiring connections
must be firm and reliable and the joints should be wrapped with insulating tape
tightly. The unused electrical wire should be properly insulated.
