2BH2A-WWS15Garbage Disposal Wireless Switch Kit

FCC 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. To assure continued compliance, any changes or modifications not expressly approved by the party. Responsible for compliance could void the user’s authority to operate this equipment. (Example- use only shielded interface cables when connecting to computer or peripheral devices). This equipment 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 Radiation Exposure Statement: The equipment complies with FCC Radiation exposure limits set forth for uncontrolled environment. This equipment should be installed and operated with minimum distance 20cm between the radiator and your body.

General Description of EUT EUT Name : Garbage Disposal Wireless Switch Kit Models No. : WWS15, WWS15-DC, WWS20, WWS20-DC Model Different : All these models are identical in the same PCB, layout and electrical circuit, the only difference is model name. Brand Name : N/A Sample ID : HC-C-202405-0327-02-01 Product Description : Operation Frequency: 433.92MHz Power Rating : Relay supply:DC 2.2V 13mA Software Version : V1.0 Hardware Version : V1.2 Remark : The antenna gain provided by the manufacturer, the verified for the RF conduction test provided by TOBY test lab. Report No.: TBR-C-202405-0327-4 Page: 2 of 3 TB-RF-074-1.0 Method of Measurement for FCC 1. Max. Antenna Gain: Mode Antenna Type Antenna Gain(dBi) 433.92 FPC -6.52 2. EUT Operation Condition: Software provided by client enabled the EUT to transmit and receive data at lowest, middle and highest channel individually. 3. Exposure Evaluation: Equation from page 18 of OET Bulletin 65, Edition 97-01 S=(PG)/4πR 2 Where S: power density P: power input to the antenna G: power gain of the antenna in the direction of interest relative to an isotropic radiator. R: distance to the center of radiation of the antenna Simultaneous transmission MPE Considerations According to KDB447498: All transmitters and antennas in the host must be either evaluated for MPE compliance, by measurement or computational modeling, or qualify for the standalone MPE test exclusion in section 7.1. Simultaneous transmission MPE test exclusion applies when the sum of the MPE ratios for all simultaneous transmitting antennas incorporated in a host device, based on the calculated/estimated, numerically modeled or measured field strengths or power density, is ≤ 1.0. This means that: ∑ of MPE ratios ≤ 1.0 Report No.: TBR-C-202405-0327-4 Page: 3 of 3 TB-RF-074-1.0 4. Test Result: Worst MPE Result Frequency (MHz) Max. Output Power (dBuV/m) Conducted Power(max) (dBm) Turn-up Power (dB) Max tune up power (dBm) [P] Max. ANT Gain (dBi) [G] Distance (cm) [R] Power Density (mW/ cm 2 ) [S] 433.92 67.46 -33.80 -33±1 -32 -6.52 20 0.000000028 Note: The antenna gain used max. antenna gain Note: For conducted measurements below 1000 MHz, the field strength shall be computed as specified in item d), and then an additional 4.7 dB shall be added as an upper bound on the field strength that would be observed on a test range with a ground plane for frequencies between 30 MHz and 1000 MHz, or an additional 6 dB shall be added for frequencies below 30 MHz. So: EIRP=E+20log3-104.8-(4.7 or 6) 5. Conclusion: As specified in Table 1B of 47 CFR 1.1310- Limits for Maximum Permissible Exposure (MPE), Limits for General Population/ Uncontrolled Exposure Frequency Range (MHz) Power density (mW/ cm 2 ) 300-1,500 F/1500 1,500-100,000 1.0 For: 2402~2480MHz MPE limit S: 1mW/ cm 2 The MPE is calculated as 0.000000028mW / cm2 < limit 1mW / cm2. So, RF exposure limit warning or SAR test are not required. The EUT will only be used with a separation of 20cm or greater between the antenna and nearby persons and can therefore be considered a mobile transmitter per 47 CFR2.1091 (b). The RF Exposure Information page from the manual is included here for reference. -----END OF REPORT-----
