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 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 causeundesired operation. Any changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. 2.2 This module has been assessed against the following FCC rule parts:CFR 47 FCC Part 15 C (15.247, DTS and DSS) and CFR 47 FCC Part 15E (NII). It is applicable to the modular transmitter 2.3 This radio transmitter 2BS3W-WKCT16 has been approved by Federal Communications Commission to operate with the antenna types listed below, with the maximum permissible gain indicated. Antenna types not included in this list that have a gain greater than the maximum gain indicated for any type listed are strictly prohibited for use with this device. The concrete contents to check are the following three points. １)Must use a PCBantennawith gain not exceeding those shown in the table below. ２)Should be installed so that the end user cannot modify the antenna ３)Feed line should be designed in 50ohm Fine-tuning of return loss etc. can be performed using a matching network. The antenna shall not be accessible for modification or change by the end user. 2.4 The module complies with FCC Part 15.247 / Part 15.407 and apply for Single module approval. 2.5 Trace antenna designs: Not applicable–the antenna is integrated into the module and cannot be modified. The device must be professionally installed The intendeduse is generally not for the general public. It is generally for industry/commercial use. The connector is within the transmitter enclosure and can only be accessed by disassembly of the transmitter which is not normally required.the user has no accessto the connector. Installation must be controlled. Installation requires special training PAGE 3OF6 2.6 This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operatedwith a minimum distance of 20cm between the radiator & your body. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter Version 1.0 . 2.7 Antenna type and antenna gain: 2.4G WIFI&5G WIFI Antennas: Antenna Frequency (MHz) Antenna Type MAX Antenna Gain (dBi) 02412-2462PCB Antenna 3.35 12412-2462PCB Antenna 0.44 Antenna No. Frequency Band Antenna Type Max Antenna Gain (dBi) 05150-5850PCB Antenna 5.03 15150-5850PCB Antenna 5.13 BT/BLEAntenna: Antenna Frequency (MHz) Antenna Type MAX Antenna Gain (dBi) 1…
