When jump starting a vehicle with this device, make sure that it is at least 50-75% charged (3 indicator LEDs are lit when the power button is pressed). To achieve optimum performance, do not store this device at temperatures below 50°F (10°C) before using as a starting aid. Never charge or start a vehicle with a frozen battery.

1. Insert the jumper cable into the jumper cable jack. Be sure that the jumper cable connection is secure. Upon connection, the LED indicator on the cable will flash in red and green, indicating that the unit is in standby mode.
2. Switch off the ignition completely before connecting the device to the vehicle.
3. . Clamp the positive (red) clamp to the positive terminal on the vehicle battery, and clamp the negative (black) clamp to the negative terminal of the car battery, the vehicle frame (ground) or other negative connection point as recommended by the vehicle manufacturer.
4. After connection, check the jumper cable to make sure the connection is correct and the battery is in the normal voltage range. The LED indicator on the jumper cable should turn on solid green if the jump starter is in normal status and ready for use.
5. Start the vehicle (turn on the vehicle ignition). NOTE: If the vehicle doesn’t start within 6 seconds, let the jump starter cool for 3 minutes before attempting to start the vehicle again or you may damage the jump starter.
6. To disconnect the jump starter cable, make sure to:
   • Disconnect the negative (black) clamp from the vehicle.
   • Disconnect positive (red) clamp from positive battery terminal.
   • Disconnect the cable from the jump starter
