  • devices to reduce the duty cycle from 50% to 15%. Staff believe the current procedure should not be relaxed. A 50% duty cycle is possible for moderate periods of time and testing the devices to ensure compliance at this level is appropriate. TIA further recommends several specific changes to the Part 15 rules. Specifically, TIA notes an error in Part 15.121(b) regarding scanning receivers, requests modification of the labeling requirements in rule 15.19, and requests clarification of the equipment authorizations required for composite devices. Staff believes there is merit in some of TIA's suggestions and recommends initiation of a review of the Part 15 rules. Other Issues The staff's thorough review of the Commission's allocation and standards rules revealed a handful

As stated in the Order, the Commission adopted the proposal from the Notice of Proposed Rule Making in this proceeding, which stated that scanning receivers must reject cellular service signals that
