Technical Characteristics of EUT Bluetooth Version: V4.2 (BDR/EDR mode) Frequency Range: 2402-2480MHz RF Output Power: 1.343dBm (Conducted) Data Rate: 1Mbps, 2Mbps, 3Mbps Modulation: GFSK,π/4-DQPSK, 8DPSK Quantity of Channels: 79 Channel Separation: 1MHz Type of Antenna: PCB Antenna Antenna Gain: 0dBi Lowest Internal Frequency of EUT: 26MHz Report No.: WTG19G03013154W-2 Page 3 of 6 FCC Part 15.247

Model: Typhon-AX12-BT 1.2 Test Standards The objective of the following report is used to demonstrate that EUT operated in a manner that ensures the public is not exposed to radio frequency energy levels in excess of the relative provisions of FCC 47CFR Part 1.1310 1.3 General Description of Test Items Description EUT Frequency band FHSS: 2.400GHz ~ 2.483GHz WLAN: 2.400GHz ~ 2.483GHz WLAN: 5.150GHz ~ 5.250GHz WLAN: 5.745GHz ~ 5825GHz Others: BT: 2402-2480MHz____ Device category Portable (<20cm separation) Mobile (>20cm separation) Others __Fixed location_ (>20cm separation)_ Exposure classification Occupational/Controlled exposure (S = 5mW/cm2) General Population/Uncontrolled exposure (S=1mW/cm2) Others: __________________________ Antenna diversity Single antenna Multiple antennas: Tx diversity Rx diversity Tx/Rx diversity Max. output power 1.343dBm = 1.40 mW Antenna gain (Max) 0 dBi Evaluation applied MPE Evaluation SAR Evaluation Note: 1. For mobile or fixed location transmitters, no SAR consideration applied. The minimum separation generally be used is at least 20 cm, even if the calculations indicate that the MPE distance would be lesser. Report No.: WTG19G03013154W-2 Page 4 of 6 FCC Part 15.247
