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.
CSM64F02 User Manual Rev1.2 Page 10 of 13 —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.

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. ② 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. ③ 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.
