Product: Wireless identification Key System Model: WKEY-2000 FCC ID : 2ABZV-WKEY-2000 Radio Frequency Human Exposure Evaluation: The highest RF output power of the EUT at 2440 MHz was measured -16.28 dBm(0.02 mW) which is less than 20mW. Since maximum peak output power of the transmitter is <60/f (GHz) mW, i.e. 0.02mW<24.59(=60/2.440)mW, hence the EUT is excluded from SAR evaluation according to FCC KDB publication 447498 D01: Mobile Portable RF Exposure.
