The following clarifies FCC’s position on when a digital device is a:
- Class B Personal Computer Peripheral (subject to DOC or Certification),
- Other Class B Digital Device (subject to Verification) or
- Class A Digital Device (subject to Verification).
Any Class B digital device that can connect to a Class B Personal Computer is a Class B Personal Computer Peripheral. “Other Class B Digital Devices” are those that never connect to a Class B PC.
When dealing with a Class A digital device that connect to a Class B PC, you’ll need to determine whether the EUT can really be categorised as Class A by considering the following:
- Is the marketing of the device restricted in such a manner that it is not sold to residential users?
- Does the application for which the device is designed generally preclude operation in residential areas?
- Is the price of the device high enough that there is little likelihood that it would be used in a residential environment, including a home business?
Only if the answer to the above 3 considerations is categorically YES, can be classed as a Class A digital device, and only Verification is required. In ambiguous situations, then it should be classed as a Class B device (either as a PC Peripheral or Other Digital Device as the case may be).
