Step 1: Insert the plug of the smart battery clamp
Insert the plug of the smart battery clamp completely into the jump starter. If the green and red light indicators on the battery clamp are flashing alternately, you are safe to move on to the next step.
Step 2: Connect the clamps
Connect the red clamp to the positive terminal (+) of the car battery and connect the black clamp to the negative terminal (-) of the car battery. If the green and red light indicators on the battery clamp are flashing alternately, you are safe to move on to the next step.
However, if the red indicator light is on:
- The battery clamp may be connected in reverse. If so, you need to disconnect the battery clamp from the vehicle and the jump starter.
- Adjust the clamps for maximum contact with battery terminals.
