X8C-EE10A1echoTM EYE for Receiver Unit

1. 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. 2. Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. NOTE: 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. 3. FCC Radiation Exposure Statement: This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. In order to avoid the possibility of exceeding the FCC radio frequency exposure limits, Human proximity to the antenna shall not be less than 20cm (8 inches) during normal operation.

Applicant: Dongguan Southstar Electronics Limited FCC ID: X8C-EE10A1 Operation Description The device uses the 2.4GHz GFSK single chip RF Transceiver nRF24L01 with embedded protocol engine (Enhanced ShockBurst™) and High performance MCU MARS MR8980B. MR8980B control the RF transceiver nRF24L01 through SPI interface. nRF24L01 receive the audio and video data sent by transmitter end. The on-chip DSP decompress the audio and video data, then show video on 320X240 resolution TFT LCD screen and play audio through the speaker. One receiver can paired with up to 4 transmitters at the same time. The receiver can choose to connect to any transmitter and can switch to others at any time. Antenna is a unique antenna. Common grounding on PCB is not connected to real external ground. Power supply is DC 3.7V by Standard Lithium Battery or DC 7.5V by adapter.

1. RF EXPOSURE 1.1. The Requirement System operating under the provisions of this section shall be operated in a manner that ensures that the public is not exposed to radio frequency energy levels in excess of the Commission’s guidelines. See Section 15.247(b)(4) and Section 1.1307(b)(1) 1.2. Limit For Maximum Permissible Exposure (MPE) Limits for General Population/ Uncontrolled Exposure F = frequency in MHz, * Plane-wave equivalent power density 1.3. MPE Calculations E(V/m) = 30 P G d ×× , Power Density: S( 2 mW/cm) = 2 377 E Where E = Electric Field (V/m) P = Peak Output Power (mW) G = Antenna Numeric Gain (numeric) = 10 x , x = Antenna Gain(dBi) /10 d = Separation Distance (cm) Frequency Range (MHz) Electric Field Strength (E) (V/m) Magnetic Field Strength (H) (A/m) Power Density (S) ( 2 mW/cm) Averaging Time 2 E, 2 H or S (minutes) 0.3-1.34 614 1.63 (100)* 30 1.34-30 824/f 2.19/f (180/f)* 30 30-300 27.5 0.073 0.2 30 300-1500 f/1500 30 1500-100,000 1.0 30 We can change the formula to: S = 2 30 377 PG d ×× × or, d = 30 377 PG S ×× × Because the EUT is belong to general population/uncontrolled exposure. So 1.3.1. We considering the limit of minimum separation distance (d) is 20cm, Maximum Output Power = 8.974mW Antenna Gain = 1(dBi) = 1.26(numeric) S = 2 30 377 PG d ×× × = 2.25 ×10 -3 2 mW/cm < 1.0 2 mW/cm (limit) Calculated RF Exposure power density is 2.25 ×10 -3 2 mW/cm , less than the limit. 1.3.2. We considering the limit of power density (S) is 1.0 2 mW/cm, Maximum Output Power = 8.974mW Antenna Gain = 1(dBi) = 1.26 (numeric) d = 30 377 PG S ×× × = 0.95cm < 20 cm Calculated RF Exposure separation distance is 0.95 cm, less than the minimum separation distance 1.3.3.FCC Radiation Exposure Statement This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. In order to avoid the possibility of exceeding the FCC radio frequency exposure limits, Human proximity to the antenna shall not be less than 20cm(8 inches) during normal operation. Proposed RF exposure safety information to include in User’s Manual.
