Certa CTJMPSTW16A - Connect Battery Clamp; Connect Clamps to Battery; Start the Car

Step 1
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 onto
the next step.
Step 2
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 onto the next step.
However, if the red indicator light is on:
1. The battery clamp may be connected in reverse. If so, you need to disconnect the
battery clamp from the vehicle and the jump starter.
2. Adjust the clamps for maximum contact with battery terminals.
Step 3
a. Start your car.
 If you failed to start your car, you need to disconnect the battery clamp from the
vehicle and the jump starter. Wait for at least 30 seconds and then try again.
 If you failed to start your car after 3 attempts, you can use the force start function.
