UserManual WiFiRelaySwitch TY-DIY-S01 FCC Statement This device complies with part 15 of the FCC rules. Operation is subject to the following two cond itions: (1) this device may not cause harmful interference, and (2) this device must accept any int erference received, including interference that may cause undesired operation. Caution: Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. NOTE: This equipment has been tested and found to comply with the limits for a Class B digital de vice, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protec tion 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 instructi ons, may cause harmful interference to radio communications. However, there is no guarantee th at interference will not occur in a particular installation. If this equipment does cause harmful int erference 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 important announcement Integration instructions for host product manufacturers according to KDB 996369 D03 OEM Manual v01 2.2 List of applicable FCC rules CFR 47 FCC PART 15 SUBPART C has been investigated. It is applicable to the modular transmitter 2.3 Specific operational use conditions This module is stand-alone modular. If the end product will involve the Multiple simultaneously transmitting condition or different operational conditions for a stand-alone modular transmitter in a host, host manufacturer have to consult with module manufacturer for the installation method in end system. 2.4 Limited module procedures This module is Limited single modular without shielding, host manufacturer have to consult with module manufacturer for the module limiting conditions when integrate the module in the host. module manufacturer should reviews detailed test data or host designs prior to giving the host manufacturer approval. 2.5 Trace antenna designs Not applicable 2.6 RF exposure considerations This 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. 2.7 Antennas This radio transmitter 2A7TT-TYDIYS01 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. Antenna No. Operate frequency band Antenna Type Maximum antenna gain 2.4GWIFI 2400-2500MHz PCB Antenna 2.5dBi 2.8 Label and compliance information The final end product must be labeled in a visible area with the following" Contains FCC ID: 2A7TT-TYDIYS01". 2.9 Information on test modes and additional testing requirements Host Host manufacturer which install this modular with limit modular approval should perform the test of radiated emission and spurious emission according to FCC part 15C:15.247 and 15.209 requirement, only if the test result comply with FCC part 15.247 and 15.209 requirement, then the host can be sold legally. 2.10 Additional testing, Part 15 Subpart B disclaimer Host manufacturer is responsible for compliance of the host system with module installed with all other applicable requirements for the system such as Part 15 B.
