Permissive Changes against Full Retest after a Firmware Update
Firmware updates altering output power, channels, or DFS logic trigger mandatory permissive change filings or retests before distribution.
Giteki Amendment
Meaning
Japanese certification updates modify the technical specifications or administrative details of a previously approved radio device. A giteki amendment is necessary when a manufacturer changes the software or the internal construction of a device certified for the Japanese market. This ensures the technical conformity mark remains valid for the shipping product.
It is the legal mechanism for keeping an approval current. This process prevents the invalidation of the mark on the physical unit.
Regulatory Change
The Ministry of Internal Affairs and Communications oversees these filings to maintain the integrity of the radio spectrum. A giteki amendment can be a simple notice for a change of company address or a complex technical update for a new antenna. Every change must be recorded in the official database.
Equipment Identity
The identification number assigned to the product is usually preserved during the update. During a giteki amendment, the body checks that the modifications do not push the emissions beyond the legal threshold. If the changes are too large, a new certification is required instead.
Submission Process
Documentation must be provided in a specific format to the registered certification body. A giteki amendment often requires a fresh set of photos showing the internal changes. Clear evidence speeds up the approval.
