| Single Modular Approval. Power Output listed is conducted. SAR compliance for specific collocated transmitter conditions in specific handheld/body-worn device was evaluated for the near-body configurations as shown in this composite filing; other collocated configurations require separate evaluation. SAR compliance for body-worn operating conditions is limited to specific belt-clips, holsters, and/or accessories tested for this filing. End-users must be informed of the body-worn operating requirements for satisfying RF exposure compliance. The highest reported body SAR values for single configurations under this FCC ID are Part 15 - 2.4GHz-band 0.14 W/kg extremity and 0.29 W/kg body. This device has 20 MHz bandwidth and 40 MHz bandwidth modes. C2PC to original FCC ID: 2AC7Z-ESPS3WROOM1 integrated into the host of BrushBot, decreased RF power and disable the BLE function as documented in this filing. |
