Class II PC is necessary to change existing GMRS-FRS (95A-95B) combination equipment intended for marketing after September 30, 2019 according to FCC KDB 888861. 3M LiteCom Plus Headset was certified on October 17, 2013, has a maximum ERP of 0.2W in the 462MHz and 467MHz frequency bands, emission designator maximum necessary bandwidth of 6K60. Therefore, it should be qualified for a Class II PC to change Form 731 line-entries from 95A (GMRS) to 95B (FRS Subpart B of Part 95). BRS Part 90 Channels (464.5-464.55 MHz and 467.7625-467.925 MHz) certified under the same FCC ID:
COZMT4610NA and available on the 3M PELTOR LiteCom Plus Models: MT7HXXX4610-NA will be remaining the same. The device continues to meet all FCC emissions requirements and there is no impact to the radio performance data that is already on file with the FCC for this transmitter. If you have any questions or comments, please do not hesitate to contact me.
