ESP8266User Manual 1. Foreword This manual mainly introduces how to use ESP8266‐based SDK for Internet of Things, including virtual machine installation, development tool usage, SDK software development kit etc. This module is limited to OEM installation only and must not be sold to end‐users. OEM integrators must be instructed to ensure that the end‐user has no manual instructions to remove or install the device. The end‐user can not remove or install this module to any other devices. 4 / 13Espressif SystemsJune 19, 2014

ESP8266User Manual 2. FCC RF exposure requirements 2.1. Standards and Regulatory Compliance 2.1.1. Standards and certification The EUT conforms to the following standards and certification requirements: 802.11 b/g/n FCC ❒ 47 CFR Part 1 ‐ RF radiation exposure limits ❒ 47 CFR Part 2 ‐ Equipment authorization ❒ 47 CFR Part C ‐ WIFI 2.1.2. FCC certification requirements According to the definition of mobile and fixed device is described in Part 2.1091(b), this device is a mobile device. And the following conditions must be met: 1. The EUT is a mobile device; maintain at least a 20 cm separation between the EUT and the user’s body and must not transmit simultaneously with any other antenna or transmitter. 2. The device is only for fixed operation mode. (A Class II Change would be required for near‐body Host applications.) 3. A label with the following statements must be attached to the host end product: This device contains Tx FCC ID: 2AC7Z‐ESP8266EX. 4. To comply with FCC regulations limiting both maximum RF output power and human exposure to RF radiation, maximum antenna gain (including cable loss) must not exceed: ❒ 802.11b band < 2.0 dBi ❒ 802.11g band <2.0 dBi ❒ 802.11n band <2.0 dBi 5. This module must not transmit simultaneously with any other antenna or 5 / 13Espressif SystemsJune 19, 2014

ESP8266User Manual transmitter 6. The host end product must include a user manual that clearly defines operating requirements and conditions that must be observed to ensure compliance with current FCC RF exposure guidelines. For portable devices, in addition to the conditions 3 through 6 described above, a separate approval is required to satisfy the SAR requirements of FCC Part 2.1093 If the device is used for other equipment that separate approval is required for all other operating configurations, including portable configurations with respect to 2.1093 and different antenna configurations. For this device, OEM integrators must be provided with labeling instructions of finished products. Please refer to KDB784748 D01 v08, section 8. Page 6/7 last two paragraphs: A certified modular has the option to use a permanently affixed label, or an electronic label. For a permanently affixed label, the module must be labelled with an FCC ID ‐ Section 2.926 (see 2.2 Certification (labelling requirements) above). The OEM manual must provide clear instructions explaining to the OEM the labelling requirements, options and OEM user manual instructions that are required (see next paragraph). For a host using a certified modular with a standard fixed label, if (1) the module’ s FCC ID is not visible when installed in the host, or (2) if the host is marketed so that end users do not have straightforward commonly used methods for access to remove the module so that the FCC ID of the module is visible; then an additional permanent label referring to the enclosed module:“ Contains Transmitter Module FCC ID: 2AC7Z‐ESPWROOM02” or“Contains FCC ID:2AC7Z-ESPWROOM02” must be used.The host OEM user manual must also contain clear instructions on how end usesers can find and/or access the module and the FCC ID. The user manual or instruction manual for an intentional or unintentional radiator shall caution the user that changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate 6 / 13Espressif SystemsJune 19, 2014

ESP8266User Manual the equipment. In cases where the manual is provided only in a form other than paper, such as on a computer disk or over the Internet, the information required by this section may be included in the manual in that alternative form, provided the user can reasonably be expected to have the capability to access information in that form. 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. Caution: Changes or modifications not expressly approved by the manufacturer could void the user’s authority to operate the equipment. 2.1.3. FCC RF exposure requirements 1. Radiated transmit power must be equal to or lower than that specified in the FCC Grant of Equipment Authorization for FCC ID: 2AC7Z‐ESPWROOM02. 2. To comply with FCC regulations limiting both maximum RF output power and human exposure to RF radiation, maximum antenna gain (including cable loss) must not exceed: ❒ 802.11b band < 2.0 dBi ❒ 802.11g band < 2.0 dBi ❒ 802.11n band <2.0 dBi 3. This module must not transmit simultaneously with any other antenna or transmitter. 4. To ensure compliance with all non‐transmitter functions the host manufacturer is responsible for ensuring compliance with the module(s) installed and fully operational. For example, if a host was previously authorized as an unintentional radiator under the Declaration of Conformity procedure without a transmitter certified module and a module is added, the host manufacturer is responsible for ensuring that the after the module is installed and operational the host continues to be compliant with the Part 15B unintentional radiator 7 / 13Espressif SystemsJune 19, 2014
