When testing a product before installation it is important to use a sufficient power source. Using an improper power supply or insufficient battery can cause the product to malfunction or even cause damage to the product. It is best to test the unit with a properly rated power supply or connected to the vehicle the product will be used on. Be sure the battery on the vehicle is fully charged. If you are unsure that your power supply for testing is sufficient read the manual or consult with the manufacturer. Using a charger or jumper pack to power any product may cause damage to that product.
