Warranty Service, which automatically entitles you to obtain warranty service throughout the warranty period.
Service will be performed by service providers authorized to perform warranty service.
Service methods and procedures vary by country, and some services might not be available in all countries.
International Warranty Service is delivered through the method of service (such as depot, carry-in, or

able to service all models of a particular machine type. In some countries, fees and restrictions might
apply at the time of service.
