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. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:
Reorient or relocate the receiving antenna. Increase the separation between the equipment and receiver. Rev1.2 Page 9 of 13 CSM64F02 User Manual Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. Consult the dealer or an experienced radio/TV technician for help. This device complies with part 15 of the FCC rules. Operation is subject to the following twoconditions:
(1) this device may not cause harmful interference, and
(2) this device must accept any interference received, including interference that may cause undesired operation. Changes or modifications to this unit not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. 5.4 Power Consumption Name Min.

Modem-Sleep is used for the application requiring CPU always in operating state such as PWM or I2S applications etc. When maintaining Wi-Fi connection, it is allowed to turn off Wi-Fi Modem circuit to save power consumption according to 802.11 standard (such as U-APSD) when there is no data transmission. For example, in the configuration of DTIM3, it will wake up for 3ms to receive Beacon packet from AP after sleeping every 300ms, and the averange current is about 15mA. Light-Sleep is used for the application with CPU suspendable such as Wi-Fi switch. When maintaining Wi-Fi connection, it is allowed to turn off Wi-Fi Modem circuit and suspend CPU to save power consumption according to 802.11 standard (such as U-APSD) when there is no data transmission. For example, in the event of DTIM3, it will wake up for 3ms to receive Beacon packet from AP after sleeping every 300ms, and the averange current will be about 9mA. Deep-Sleep is used for the application without the need to always maintain Wi-Fi connection and transmitting one data packet for a long time such as the sensor measuring temperature every 100s. For example, it will wake up for 0.3s - 1s every 300s and connect to AP to transmit data, and the averange current may be far smaller than 1mA.

(Top View) Rev1.2 Page 13 of 13 Host 15B and 15C compliance statement A host product itself is required to comply with all other applicable FCC equipment authorization regulations, requirements, and equipment functions that are not associated with the transmitter module portion. For example, compliance must be demonstrated: to regulations for other transmitter components within a host product;
to requirements for unintentional radiators (Part 15 Subpart B), such as digital devices, computer peripherals, radio receivers, etc.; and to additional authorization requirements for the non-transmitter functions on the transmitter module (i.e., Verification or Declaration of Conformity) as appropriate (e.g., Bluetooth and Wi-Fi transmitter modules may also contain digital logic functions). The OEM integrator or the host manufacturer is responsible for the overall compliance of the host products FCC statement This device complies with Part 15 of 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. RF exposure statement Human exposure to RF emissions from mobile devices (47 CFR 2.1091) may be evaluated based on the MPE limits adopted by the FCC for electric and magnetic field strength and/or power density, as appropriate, since exposures are assumed to occur at distances of 20 cm or more from persons. Module statement The single-modular transmitter is a self-contained, physically delineated, component for which compliance can be demonstrated independent of the host operating conditions, and which complies with all eight requirements of 15.212(a)(1) as summarized below. 1) The radio elements have the radio frequency circuitry shielded. 2) The module has buffered modulation/data inputs to ensure that the device will comply with Part 15 requirements with any type of input signal. 3) The module contains power supply regulation on the module. 4) The module contains a permanently attached antenna. 5) The module demonstrates compliance in a stand-alone configuration. 6) The module is labeled with its permanently affixed FCC ID label 7) The module complies with all specific rules applicable to the transmitter, including all the conditions provided in the integration instructions by the grantee. 8) The module complies with RF exposure requirements. FCC statement The final host device, into which this RF Module isintegrated" hasto be labelled with an auxilliary lable stating the FCC IDofthe RF Module,such as"
"Contains FCC ID:2AGM5CSM64F02"
