User Guide WRZ Radio Module 2.4G Issue Date May 31, 2012 3 WRZ Radio 2.4GHz Module User Guide FCC and Industry Canada: The JCI user manual for the end product that has this radio module integrated in to it must include the following information in a prominent location: “To comply with FCC and Industry Canada RF radiation exposure limits for general population, the antenna(s) used for this transmitter must be installed such that a minimum separation distance of 20cm is maintained between the radiator (antenna) and all persons at all times and must not be co-located or operating in conjunction with any other antenna or transmitter.” The manual must also not provide information regarding how to install or remove this RF module or change RF related parameters. The Johnson Controls WRZ Radio 2.4G RF module has been certified for integration into products only by OEM integrators under the following conditions: 1) The antenna must be installed such that a minimum separation distance of 20 cm is maintained between the radiator (antenna) and all persons at all times. 2) The transmitter module must not be co-located or operating in conjunction with any other antenna or transmitter. As long as the two conditions above are met, further transmitter testing will not be required. However, the OEM integrator (JCI only) is still responsible for testing their end-product for any additional compliance requirements required with this module installed (for example, digital device emissions). IMPORTANT NOTE: In the event that these conditions cannot be met (for certain configurations or co-location with another transmitter), then the FCC and Industry Canada authorizations are no longer considered valid and the FCC ID and IC Certification Number cannot be used on the final product. In these circumstances, the OEM integrator (JCI) will be responsible for re-evaluating the end product (including the transmitter) and obtaining a separate FCC and Industry Canada authorization. END PRODUCT LABELING The WRZ Radio 2.4G RF Module is labeled with its own FCC ID and IC Certification Number. If the FCC ID and IC Certification Number are not visible when the module is installed inside another device, then the outside of the device into which the module is installed must also display a label referring to the enclosed module. In that case, the final end product must be labeled in a visible area with the following: “Contains Transmitter Module FCC ID:OEJ-WRZRADIO” “Contains Transmitter Module IC: 279A-WRZRADIO” Or “Contains FCC ID: OEJ-WRZRADIO” “Contains IC: 279A-WRZRADIO” The WRZ Radio 2.4G RF Module must only use the approved antenna(s) listed in this document, which have been certified with this module.
