Installation of equipment： A. Install the copper pillar first： 5 B. And then install the upper plate： Screw the screws and lead copper posts on the upper plate C. Install low frequency antenna： Tip: The low-frequency antenna can also be installed in four symmetrical positions on the top, bottom, left, and right, and you can choose according to your preferences. In the recommended way, the two antennas have the least influence on each other. 6 2. IC HF card placement location： The IC card is recommended to be placed on the back of the device and aligned with the device, which is the most stable. 7 Place the card as shown in the picture above. Normally, there is no problem. In addition, please keep away from metal objects and metal tabletops. Individual keychains or small cards with poor signals can easily interrupt the reading and writing. At this time, you can read the card as shown in the figure below and put the low-frequency antenna under the high-frequency antenna to solve the problem. 3.

Shenzhen CTB Testing Co., Ltd. FCC ID: 2A52C-EASY30 Portable device Per § 1.1307(b)(3)(i)(A), a single RF source is exempt RF device (from the requirement to show data demonstrating compliance to RF exposure limits, as previously mentioned) if the available maximum time-averaged power is no more than 1 mW, regardless of separation distance. This exemption applies to all operating configurations and exposure conditions, for the frequency range 100 kHz to 100 GHz, regardless of fixed, mobile, or portable device exposure conditions. This is a standalone exemption, and it cannot be applied in conjunction with any other test exemption. 125kHz: Note:dbm=dbuv/m-95.2=73.14-95.2=-22.06dBm(EIRP), so the maximun averaged power power=0.0062mW Conclusion: For the max result : 0.0062≤ FCC Limit 1mW for 1g SAR. 125kHz+13.56MHz supported simultaneous transmission: 125kHz+13.56MHz MIMO : ∑MPE Ratio =0.0062+0.0008=0.007≤1, So passed.
