LLC742x RF Node User Manual 1. General Information The individual RF module named as LLC742x RF Node, FCC ID: 2AGBWLLC742X and IC: 20812-LLC742X, is supplied by DC 3.8V . The transmitter has its own RF shielding. The operation temperature range is ‐40°C‐85°C. This module using only one kind of antennas with maximum gain is ‐2 dBi. Any Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. The picture of module is as showed in below pictures. The module will be installed in final products as showed below. The module will be installed here.Final product 2. Information on Test Modes and Additional Testing Requirements a. The modular transmitter has been fully tested by the module grantee on the required number of channels, modulation types, and modes, and it’s complied with FCC part 15.247. It should not be necessary for the host installer to re‐test all the available transmitter modes or settings. It is recommended that the host product manufacturer, installing the modular transmitter, perform some investigative measurements to confirm that the resulting composite system does not exceed the spurious emissions limits or band‐edge limits(e.g., where a different antenna may be causing additional emissions). b. The testing should check for emissions that may occur due to the intermixing of emissions with the other transmitters, digital circuitry, or due to physical properties of the host product (enclosure). This investigation is especially important when integrating multiple modular transmitters where the certification is based on testing each of them in a stand‐alone configuration. It is important to note that host product manufacturers should not assume that because the modular transmitter is certified that they do not have any responsibility for final product compliance. c. If the investigation indicates a compliance concern the host product manufacturer is obligatedtomitigatetheissue.Hostproductsusingamodulartransmitteraresubjectto all the applicable individual technical rules as well as to the general conditions of operation in Sections 15.5, 15.15, and 15.29 to not cause interference. The operator of the host product will be obligated to stop operating the device until the interference has beencorrected. Below are steps for TX verification：rx 0//Rx: Disabled set channel//set channel to 1, 2, 3, 4 ~10etc. set power110 //set Tx power to 11dBm set Tx Stream 1//start continuous modulated Tx set Tx Stream 0//stop continuous Tx Note: This module only has one kind of modulation type, OQPSK. The physical rate is 250Kbps. d. The Class A or Class B compliance check in the end‐pr oduct which uses NARF module according to FCC part 15B should be checked with the end‐product. Any Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. 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. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. 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 instruction s, 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 i nterference 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. FCC Radiation Exposure Statement: Thi s equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment .This equipment should be installed and operated with minimum distance 20cm between the radiator& your body. ISED Statement This device complies with Industry Canada license -exempt RSS standard(s).
