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. RF warning statement: The device has been evaluated to meet general RF exposure requirement. The device can be used in portable exposure condition without restriction.

Client Information Applicant : Doc johnson Enterprises Address : 11933 Vose Street, North Hollywood, CA 91605 Manufacturer : Odeco Ltd. Address : 2F, Block 7th YuSheng Industrial Zone, Xixiang, Bao'an District, Shenzhen, China 2. General Description of EUT EUT Name : TRYST 2.0 Models No. : I-MX-0990-16, I-MX-0990-17, I-MX-0990-15 Model Difference : All these models are in the same PCB, layout and electrical circuit, the only difference is appearance color. Product Description : Operation Frequency: 433.92 MHz Max. Output Power: 59.93dBuV/m(-35.32dBm)( 0.00029mW) Antenna Gain: PCB Antenna(0 dBi) Modulation Type: ASK Power Rating : DC 1.5V AAA battery Software Version : 041772 Hardware Version : PCB-2197MG A1 Connecting I/O Port(S) : Please refer to the User's Manual Note: More test information about the EUT please refer the RF Test Report. Report No.: TB-MPE172586 Page: 2 of 3 TB-RF-074-1.0 Standard Requirement Portable Device According to §15.247(i) and §1.1307b(1), systems 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 KDB 447498 D01 General RF Exposure Guidance V6, section 4.3.1. The 1-g and 10-g SAR test exclusion thresholds for 100 MHz to 6 GHz at test separation distances ≤ 50 mm are determined by: [(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)] ·[√f(GHz)] ≤ 3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR,16 where ·f(GHz) is the RF channel transmit frequency in GHz ·Power and distance are rounded to the nearest mW and mm before calculation17 ·The result is rounded to one decimal place for comparison The test exclusions are applicable only when the minimum test separation distance is ≤ 50 mm and for transmission frequencies between 100 MHz and 6 GHz. When the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine SAR test exclusion. Report No.: TB-MPE172586 Page: 3 of 3 TB-RF-074-1.0 Measurement Result: Test separation: 5mm Frequency (GHz) Max. E (dBuV/m) D (m) Max Output power (dBm) Max Output power (mW) Calculation Value (Note 1) Threshold Value 433.92 59.93 3 -35.33 0.0003 0.00004 3.0 Note: EIRP=E-104.8+20logD Note 1: Calculation Value =[(max. power of channel, mW)/(min.test separation distance, mm)] ·[√f(GHz)]. According to KDB447498 D01 V6, threshold at which no SAR required is ≤3.0 for 1-g SAR, separation distance is 5mm, and no simultaneous SAR measurement is required. Standard Applicable According to 2.1093 this is a portable device. According to KDB 447498 D01 V6, Appendix A SAR test exclusion thresholds for below table, the power level 22mW at 5mm. Measurement Result: This is a portable device and the Max. peak output power is -35.32dBm(0.00029mW) lower than low threshold 22mW at 5mm in general population category; The SAR measurement is not necessary. -----END OF REPORT-----
