RF Exposure requirements Product name SMART KEY TAG Model number A242 FCC ID ZE8-A242 Radio specification 2.4 GHz ZigBee transceiver, 125 kHz RFID receiver Antenna 2.4 GHz, integral SMD chip antenna, 125 kHz, Resonance coil Power source DC 3 V lithium battery According to the KDB 447498, the following standalone SAR test exclusion was considered to qualify for the SAR test exclusion. Tx frequency range 2405 MHz - 2480 MHz Device category Handheld portable device Maximum conducted output power 1.24 mW (0.95 dBm) Limit 10 mW (distance = 5 mm) SAR test exclusion thresholds: [(max. power of channel, mW) / (min. separaƟon distance, mm ] · √f (GHz) ≤ 3.0 for 1‐g SAR and ≤ 7.5 for 10‐g extremity SAR MHz 5 10 15 20 25 30 35 40 45 50 test separation distance (mm) 2450 10 19 29 38 48 57 67 77 86 96 SAR test exclusion threshold (mW) The source-based time-averaged maximum conducted output power of the RF channel is less than 10 mW, and therefore the transmitter complies with the RF exposure requirements and the SAR is not required.
