XZF-RC826DIGITAL WIRELESS RECEIVER

FCC warning statement This equipment 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. 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. • 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 equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with minimum 20 cm between the radiator and your body. This transmitter must not be collocated or operating in conjunction with any other antenna or transmitter unless authorized to do so by the FCC. Changes or modifications not expressly approved by the party responsible for compliance. could void the user's authority to operate the equipment.

General Appearance of the EUT

FCC ID: XZF-RC826 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.

FCC ID Lable Location On EUT

Antenna

Camera CM241 transmitt the image signal to MCU to dispose......And it will be sent to the receiver RC826 through RF wireless module......later, RF module in receiver receives the signal and transimit it to MCU to dispose,Finally,the signal be sent and reverted to LCD Sound： Camera CM216 telephone transmitter transmit the sound signal which is blew up circuit to MCU to dispose. And it will be sent to the receiver RC826 through RF wireless module, later,RF module in receiver receives the signal and transimit it to MCU to dispose,Finally, the sound signal will be blew up and reverted in amplifier circuit.

RF EXPOSURE EVALUATION According to FCC 1.1310: The criteria listed in the following table shall be used to evaluate the environment impact of human exposure to radio frequency(RF) Radiation as specified in §1.1307(b) FCC ID：XZF-RC826 EUT Specification EUT DIGITAL WIRELESS RECEIVER Frequency band (Operating) WLAN: 2.412GHz ~ 2.462GHz WLAN: 5.18GHz ~ 5.32GHz / 5.50GHz ~ 5.70GHz WLAN: 5.745GHz ~ 5825GHz Others Device category Portable (<20cm separation) Mobile (>20cm separation) Others ___ Exposure classification Occupational/Controlled exposure (S = 5mW/cm2) General Population/Uncontrolled exposure (S=1mW/cm2) Antenna diversity Single antenna Multiple antennas Tx diversity Rx diversity Tx/Rx diversity Max. output power 9.21dBm (8.33mW) Antenna gain (Max) 0 dBi Evaluation applied MPE Evaluation SAR Evaluation Limits for Maximum Permissible Exposure(MPE) Frequency Range(MHz) Electric Field Strength(V/m) Magnetic Field Strength(A/m) Power Density(mW/cm 2 ) Average Time (A) Limits for Occupational/Control Exposures 300-1500 -- -- F/300 6 1500-100000 -- -- 5 6 (B) Limits for General Population/Uncontrol Exposures 300-1500 -- -- F/1500 6 1500-100000 -- -- 1 30 Friis transmission formula: Pd=(Pout*G)\(4*pi*R2) Where Pd= Power density in mW/cm 2 Pout=output power to antenna in Mw G= gain of antenna in linear scale Pi=3.1416 R= distance between observation point and center of the radiator in cm Pd the limit of MPE, 1mW/cm2.
