QKWFRF905Transceiver module

Guidelines when using the radio unit FRF905 in Fronius products • Range of validity: These guidelines have to be applied, when the concerning product is used in countries, in which a certification of a radio unit as prescribed by FCC 47 C.F.R. § 15.247, is ac- cepted for its use. All mentioned points have to be fulfilled. • Only the layouts with the belonging equipments, used in the radio device certification, may be used. • Usable frequencies: 902,4-927,6 MHz in the 0,4 MHz-scheme. At least 50 different frequencies must be used here, after a pseudo random principle, whereby each frequency may be used within any 20s-intervals for maximum 0,4s. • useable antennas: o internal antenna ANT-916-JJB-ST o external antennas over SMA-plugs: ANT-DB1-RMT-SMA-2mRG174 or PSKN3-890S • The following transmitting powers with the corresponding time on air and antennas have to be kept: Antenna maximum transmit- ting power [dBm] TOA each 100ms [%] 1 10 50 PSKN3-890S 6 100 ANT-DB1-RMT- SMA-2mRG174 10 100 ANT-916-JJB-ST 10 100 • The supply voltage must be within the range of 1,9 – 3,6 V (at minimum 30mA load capacity) • In the case of the use of an external antenna, the antenna plug may not be accessible from the outside (plug rises up from the equipment). If this is nevertheless absolutely necessary, an RP- SMA antenna plug (“unique antenna connector”) must be used. Accordingly the plug of the an- tenna, which can be attached (ANT-DB1-RMT-SMA-2mRG174 and/or PSKN3-890S), has also to be changed. • The inscription „Contains FCC ID: QKWFRF905“ has to be attached readably from the outside (and/or in a general manner) on the product Reference: [1] Data sheet of transceiver nRF905 V1.2 (download: http://www.nordicsemi.no ) 1 The TOA (time on air) is to be calculated as prescribed by [1] page 25. Measurement: Low-Hi-transition of the signal TX_EN to the Hi-Low-transition of the signal DR of the nRF905.

REQUEST FOR CONFIDENTIALITY for the following product: FCC-IDENTIFIER: QKWFRF905 List of confidental documents: Exhibit Subject Exhibit 05 Schematic Diagrams Exhibit 09 Internal Photos (without shielding) Exhibit 05 Layouts Exhibit 12 Brochures We want to have this documents confidential according to 47 CFR 0.457(d) of the FCC Rules, because this information is the own and an essential part of the know how of our company, it is considered as a trade secret and will not be provided to the public. Best regards Gerald Ortner Fronius International

RF exposure compliance issues: The unit uses a very low eirp level of not more than 10 mW. So it is excluded from routine RF exposure evaluation.
