If your product exhibits specific performance problem(s) where the Troubleshooting Section recommends a counterclockwise needle adjustment and you have made no adjustments since the original purchase, take the product to a factory authorized service center for repair. In most cases, the needed adjustment is a simple task for the factory trained service representative.
