# §15.405. Cross reference.

- (a) The provisions of subparts [A](/cfr/47/subpartA.md), [B](/cfr/47/subpartB.md), and C of this part apply to unlicensed U-NII devices, except where specific provisions are contained in subpart E. Manufacturers should note that this includes the provisions of §§ [15.203](/cfr/47/15.203.md) and [15.205](/cfr/47/15.205.md).
- (b) **The requirements of subpart E apply only to the radio transmitter contained in the U-NII device.** Other aspects of the operation of a U-NII device may be subject to requirements contained elsewhere in this chapter. In particular, a U-NII device that includes digital circuitry not directly associated with the radio transmitter also is subject to the requirements for unintentional radiators in subpart B.
