Valid Documents
Only the latest valid official documents are used externally.
CERTIFICATIONS & TESTING
Public information explains model and document relationships and does not replace original certificates, registrations or test reports.

PUBLICATION PRINCIPLES
Certification and testing resources must be checked for document name, validity, covered models and independent-certificate or coverage relationships.
Only the latest valid official documents are used externally.
A covered model does not mean every model has an independent certificate.
Reports and internal files without confirmed public permission are not placed in the download center.
