FCC ID 2A7Z4-KQN Antenna gain (Max) 1.9dBi Operation Frequency 2402 MHz to 2480 MHz Power Supply AC 120V/60Hz DC 5V Battery 3.7V Classification Per Stipulated Test Standard §15.247(i), §2.1093 Modulation GFSK Max. output power 0.32dBm (0.0011W) Test Requirement: According to ß15.247(i) and ß1.1307(b)(1), systems operating under the provisions of this section shall be operated in a manner that ensures that the public is not exposed to radio frequency energy level in excess of the Commission’s guidelines. Page 2 of 2 Routine SAR evaluation refers to that specifically required by ß2.1093, using measurements or computer simulation. When routine SAR evaluation is not required, portable transmitters with output power greater than the applicable low threshold require SAR evaluation to quality for TCB approval. One antenna is available for the EUT. The minimum separation distance is 5mm.
