GV-Compact DVR V2 Anti-Vibration ACC Model: GV-LX4C2V
GV-Compact DVR V3 Anti-Vibration ACC Models: GV-LX4C3V, GV-LX8CV1, GV-LX8CV2

Introduction
The Anti-Vibration ACC models are designed to control the operation of GV-Compact DVR through the ACC wire from your vehicle. When you turn on the ignition, the GV-Compact DVR will not start up immediately but do start after 5 seconds. After you turn off the ignition, the GV-Compact DVR will continue operating for 30 seconds, during which it will stop recording, removing the hard disk from the system and then shut down automatically.

The ACC design provides a protection against sudden power surge and outage which can cause failure of the GV-Compact DVR and the hard disk, corruption of data on the hard disk and other unexpected errors.

Since each vehicle differs in design, refer to the owner’s manual of your vehicle for details and carefully follow the safety measures. If you are unsure about how to carry out the ACC connection, have the installation done by a properly trained technician.

Connecting Anti-Vibration ACC Models to a Vehicle
The instructions are based on installation on a Toyota Zace Surf. First, you will need to connect the vehicle’s ACC wire to the GV-Compact DVR. Next, connect the supplied power cable to your vehicle.

Connecting the ACC Wire
  1. Locate the fuse box. The fuse box is usually located below the dashboard and to the left of the steering wheel. You may need to refer to the owner’s manual of your vehicle.

  3. Find the fuse specification diagram in the owner’s manual, which tells you what each fuse controls. Look for the fuse location of the “cigarette lighter.” The fuse diagram is sometimes located on the back of the fuse box cover.
  4. Connect the ACC wire from the cigarette lighter fuse to Pin 16 (4-channel unit) or Pin 24 (8-channel unit) on the terminal block.

Connecting the Power Wire
The supplied power cable of the Anti-Vibration ACC model splits into two wires. Connect the white wire to the vehicle’s power cable and use the black wire to make the ground connection.

Note: The Compact DVR V3 supports the power input of 10V to 28V, 5A.

  1. Using the fuse specification diagram, locate the power cable connecting to the fuse box. Connect the white power wire of the GV-Compact DVR to the positive-voltage power cable. You may need to use a voltmeter to determine which one is the positive voltage.

  3. Use one of the two methods below to connect the black ground wire of the GV-Compact DVR.
    • Method 1: Connect the black ground wire to the negative-voltage power cable from the fuse box.

    • Method 2: Connect the black ground wire to the vehicle’s chassis so that the wire contacts the bare metal, for example, a metal bolt nearby.

    Depending on the make and model of your vehicle, sometimes only one method will work. When the black ground wire is connected correctly, the GV-Compact DVR will automatically shut down 30 seconds after the car’s power is off. If the GV-Compact DVR does not shut down 30 seconds after the car ignition is off, try to connect the black ground wire using the other method.
     
  4. Turn on the car ignition and the GV-Compact DVR should start automatically within 5 seconds. Turn off the car ignition and the GV-Compact DVR should shut down 30 seconds after the car ignition is off.
