Executing Class Two Permissive Changes for Substituted Host Antennas
Substituted host antennas qualify for Class II Permissive Changes only when peak gain stays below certified limits and radiative physical structure remains identical.
Giteki Modification
Meaning
Regulatory adjustments for the Japanese market involve updating the certification of a product after hardware or software changes. The giteki modification process ensures that the modified unit still adheres to the strict rules of the region. Because the original certification is tied to a specific design, any change usually requires a re-evaluation or a notification to the certification body.
This procedure maintains the legal status of the technical conformity mark.
Certification Continuity
Manufacturers must track every component swap to determine if the giteki modification triggers a mandatory new filing. A simple change in an antenna trace or a power increase in the firmware often necessitates a repeat test. Maintaining the validity of the mark requires a clear audit trail of these changes.
Import Risk
Unrecorded changes can lead to shipments being held at customs or a total revocation of the mark for that product line. Inspectors compare the internal layout of the device against the original filing photos. If the giteki modification was not properly documented, the product is considered uncertified.
Software Update
Digital certificates and encryption keys sometimes require updates that affect radio performance. Security patches must be implemented without violating the original grant parameters.
