For example, the grantee code for FCC ID: 2BBZH-K380S is 2BBZH. The remaining characters of the FCC ID, -K380S, are often associated with the product model, but they can be random. These letters are chosen by the applicant. In addition to the application, the FCC also publishes internal images, external images, user manuals, and test results for wireless devices.
