Using this power cable is easy. First, locate the power supply and find an available output. Take the end with the 2.1mm straight male plug and insert it into the output of the power supply. Then, take the other end with the 2.1mm right - angle male plug and connect it to your effects pedal. That's it! Your pedal should now be powered. When using this cable, make sure the power supply is turned off before making any connections to avoid short - circuits. Also, don't bend the cable too sharply as it might damage the internal wires. For maintenance, keep the cable clean and dry. If it gets dirty, you can gently wipe it with a soft, dry cloth. Store it in a cool, dry place when not in use to extend its lifespan.
