2AC7Z-ESP32WATG32DWi-Fi & Bluetooth Internet of Things Module

FCC Label: The FCC ID is on the front of the device. It is easily visible. The device FCC ID is 2AC7Z‐ESP32WATG32D. A label with the following statements must be attached to the host end product: This device contains FCC ID: 2AC7Z‐ESP32WATG32D. The manual provides guidance to the host manufacturer will be included in the documentation that will be provided to the OEM. The module is limited to installation in mobile or fixed applications. The separate approval is required for all other operating configurations, including portable configurations and different antenna configurations. The OEM integrators are responsible for ensuring that the end‐user has no manual or instructions to remove or install module. The module is limited to OEM installation ONLY. Module grantee (the party responsible for the module grant) shall provide guidance to the host manufacturer for ensuring compliance with the Part 15 Subpart B requirements. The host manufacturer is responsible for additional testing to verify compliance as a composite system. When testing the host device for compliance with the Part 15 Subpart B requirements, the host manufacturer is required to show compliance with the Part 15 Subpart B while the transmitter module(s) are installed and operating. The modules should be transmitting and the evaluation should confirm that the module’s intentional emissions are compliant (i.e. fundamental and out of band emissions) with the Radio essential requirements. The host manufacturer must verify that there are no additional unintentional emissions other than what is permitted in the Part 15 Subpart B or emissions are complaint with the Radio aspects. CAUTION: Any changes or modifications not expressly approved by the grantee of this device could void the user’s authority to operate the equipment. FCC RF Exposure Requirements This device complies with FCC RF radiation exposure limits set forth for an uncontrolled environment. The antenna(s) used for this transmitter must not be co‐located or operating in conjunction with any other antenna or transmitter and must be installed to provide a separation distance of at least 20cm from all persons. FCC Regulations This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. This device has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications.
