Sirona Dental Systems GmbH Maintenance Instructions
General
To stay in compliance with the DHHS requirements the ORTHOPHOS®3 / 3 Ceph must be maintained an­nually following date of installation. It is the responsibility of the user to insure that the equipment is maintained with the manufacturer's recommended The manufacturer and the assembler/installer are relieved from responsibility in those cases where noncompliance with the standard results from the user's failure to have the manufacturer's recommended maintenance performed. The actual maintenance inspection and consequent service must be accomplished by a trained serviceman. Neither the inspection nor service is part of the equipment warranty.
