Response to TCB Findings 11.20dB bandwidth of 255kHz is higher than the declared channel separation of 250kHz. According to 15.247(a)(1), frequency hopping systems shall have hopping channel carrier frequencies separated by a minimum of 25kHz or the 20dB bandwidth of the hopping channel, whichever is higher. How does the device comply with this requirement? Please clarify. Please refer the document labelled RFI TCB response. The 20 dB bandwidth has been remeasured at being less than 250 kHz. As a result the device utilises a minimum of 50 channels. 12. Please clarify what was meant with ">-41dBm" for out of band conducted emissions on Pg 20 and 21 of the report. With reference pages 20 and 21, all spurious emissions observed from the device were greater than 20 dB of the limit however for completeness for my client I have recorded the levels that I observed. At 1800 MHz, being 2 * fc it was difficult to record a level that was not causing the spectrum analyser to be overloaded. So -41 dBm was the level recorded where the emission could no longer be observed indicating that the emission had a true value being less than -41 dB. One attenutator step back the level was still not a true level as the analyser was still be overloaded. 13. For radiated emissions above 1GHz, have peak levels of the emissions (with 1MHz RBW and VBW) complied with 74dBuV/m limit (20dB above average)? Also the data tables have no readings on them, does this mean no emissions have been recorded? What was the noise floor of the measurement system? Please clarify. Emission measurements were initially made at a distance of 3 metres with no spurious emissions being detected. Additional measurements were made at a closer distance of approximately 1 metre with no emissions also being detected. Measurements were made in average with checks also made in peak but no emissions were detected in this mode. Between 1 - 9 GHz a noise floor starting at approximately 25 dBuV/m working its way up to approximately 44 dBuV/m was observed. Moving into a distance of 1 metre allowed the margin to the limit to be increased by an additional 10 dB which allowed a 20 dB margin to the limit. 14. The radiated emissions test set-up photos does not show the antenna connected to the device as seen in AC line conducted emissions test set-up photo. Was the antenna connected to the board during radiated emissions test? Has the antenna position of the device been varied in all possible orthogonal orientations to maximize the emissions? Please clarify. Emission measurements were made in two modes. - with the antenna terminal terminated with a dummy load - with an antenna attached The photographs have been taken with the dummy load attached. The results obtained were identical. When the antenna was attached to the device the antenna was placed in a vertical postion and it was rotated using the turntable and the polarisation of the receiving antenna was changed between vertical and horizontal. This process was also carried out when the dummy load was attached. 15. Please supply EIRP readings calculated from the fundamental field strength reading of the emission (on 3 channels). This is needed to verify that the measured EIRP complies with the 36dBm limit. The maximum power output of the device and the antenna gain give a theoretical radiated power output of 34.9 dBm. The limit is 36 dBm. Using the antenna described in the report the following radiated power measurements were determined: The worst case power level determined was 31.9 dBm. Details of these measurements are contained within a file labelled radiated power. 16. Please confirm that a 50ohm/50uH LISN has been used for AC line conducted emissions test. A Rohde and Schwarz ESH2-Z5 Artifical mains network was used to make AC line conducted emission measurements. This is a 50 ohm / 50 mirohenry mains network.

Layout diagrams have been mentioned in the confidentiality request. This document was not supplied. Please provide the document or revise the confidentiality request. Please refer to CD Rev 1.0.3, under the directory “/PCB Overlays”. 4.2 Operational Description 2. An operational description is required as a separate exhibit. If this is part of the manual, it needs to be extracted and supplied. This description should also address the following issues; The mentioned issues are dealt with separately below. 4.2.1 Pseudo-random hopping sequences a. Is the hopping sequence pseudorandom? Provide examples of the hopping sequence. The hopping pattern sequences are pseudo-random. Hopping pattern sequences are calculated using a linear congruential generator, of the form [11]: () mbayy nn mod 1 += + The MINSTD generator is used, having constants: 0 168077 214748364712 5 31 = == =−= b a m The procedure for generating the 32 hopping patterns is as follows. 1. Set y 0 = 389. RF Innovations Pty Ltd Report on FCC Compliance RD0565 Rev 4.1 Page 19 of 38 04-08-23 2. Generate the first hopping pattern channel c 1 by calculating (y 1 mod MAX_CHANNELS 3 ). 3. Generate the n th hopping pattern channel by calculating (y n mod MAX_CHANNELS). If this is the same as any of the channels c 1 to c n-1 already in the sequence, discard the result and use (y n+1 mod MAX_CHANNELS) instead. Repeater until a valid hopping pattern channel is found. 4. Repeat step 3 until such time as a full hopping pattern is generated. 5. Repeat steps 2, 3, and 4 until each hopping pattern is generated. An example of different hopping patterns is provided in Table 12 below [12]. HSN stands for “Hopping Sequence Number”. The slot number corresponds to the FCC channel number visited in successive time slots. HSN [0..31] Slot Number [0..101] 0 29, 98, 26, 30, 17, 99, 36, 64, 79, 74, 13, 9, 85, 57, 61, 89, 8, 81, 69, 96, 75, 14, 6, 33, 15, 22, 34, 95, 45, 23, 2, 35, 32, 83, 41, 78, 90, 43, 12, 87, 53, 21, 3, 80, 48, 40, 7, 91, 42, 16, 1, 54, 38, 44, 18, 73, 20, 71, 62, 101, 11, 52, 39, 47, 82, 4, 58, 97, 46, 56, 60, 55, 50, 25, 37, 77, 19, 94, 70, 67, 88, 76, 0, 27, 24, 100, 5, 93, 49, 68, 72, 31, 92, 65, 63, 86, 66, 51, 28, 59, 10, 84 16 81, 90, 31, 77, 100, 70, 86, 53, 68, 3, 62, 58, 41, 92, 1, 28, 61, 46, 101, 79, 20, 4, 60, 91, 24, 93, 87, 12, 35, 40, 57, 73, 19, 48, 27, 6, 69, 95, 7, 74, 36, 49, 55, 5, 33, 59, 54, 30, 51, 82, 42, 25, 85, 29, 56, 64, 45, 8, 17, 2, 34, 80, 38, 22, 63, 52, 71, 13, 65, 83, 32, 78, 10, 76, 18, 9, 66, 88, 67, 75, 89, 37, 47, 96, 50, 98, 0, 26, 16, 84, 44, 14, 15, 99, 43, 94, 21, 39, 72, 11, 97, 23 31 96, 55, 25, 100, 95, 64, 91, 12, 40, 97, 10, 17, 45, 31, 81, 101, 51, 65, 73, 47, 6, 79, 82, 61, 59, 36, 20, 77, 88, 34, 14, 4, 50, 15, 84, 44, 76, 32, 43, 46, 52, 74, 18, 66, 86, 70, 68, 71, 22, 42, 67, 63, 75, 8, 94, 16, 1, 7, 69, 2, 53, 99, 62, 19, 85, 28, 54, 23, 48, 29, 3, 58, 38, 0, 90, 78, 39, 5, 24, 37, 21, 57, 41, 9, 98, 72, 93, 27, 92, 49, 33, 60, 35, 30, 26, 11, 13, 56, 89, 80, 83, 87 Table 12: Example FCC hopping patterns In addition to the standard 32 hopping patterns, three additional patterns are supplied that are only available in factory mode, as shown in Table 13 below. These patterns cannot be used to link or transfer data, they are only used for the purpose of testing the VCO range. HPSN Description 32 Hops between channels 0 and 100 only. 33 Only hops over the lower 50% of the band. 34 Only hops over the higher 50% of the band. Table 13: Factory mode hopping patterns 4.2.2 Equi-probable channels b. How is the equal use of each channel on average ensured by the device? 3 MAX_CHANNELS = 102, for the FCC image. RF Innovations Pty Ltd Report on FCC Compliance RD0565 Rev 4.1 Page 20 of 38 04-08-23 The method for generating the hopping sequence described in 4.2.1 ensures that within each hopping sequence, each of the 102 channels occurs once. Under normal operation the hopping sequence is cycled i.e. after the EUT has dwelled on the last channel in the sequence it will then hop back to the first and then hop through the sequence ad infinitum. Therefore each channel is visited once every 102 channels. The frame time is the amount of time that the RFI-9256 will spend on each channel in the hopping pattern. This is also referred to as the channel dwell time. [9] The frame time is user-configurable, 5ms to 35ms [9] with the one setting being applied to all the channels in the hopping sequence. Therefore equal use of all channels is guaranteed. Some evidence for this is shown in the following figure. Figure 5 :Channel frequency tuning voltage In figure 5 the lower trace is the tuning voltage on the channel changing main VCO of the EUT measured at TP1 of the circuit. The upper trace is the TX/RX switch line measured at TP34 and was used to trigger the oscilloscope. The vertical time cursors show where the pattern repeats indicating the period for a complete 102 channel hopping sequence. 4.2.3 Compliant receiver bandwidth c. Does the associated system receiver have a compliant input bandwidth, based on the measured 20 dB emission bandwidth? The RFI-9256 OEM module receiver bandwidth is determined by its last (2 nd ) IF (10.7MHz). The IF filter used is Murata SFELA10M7JAA0-B0. Refer to filter characteristics in Figure 6 below. As can be seen, the filter bandwidth comfortably fits within the declared 20dB channel bandwidth (250KHz). RF Innovations Pty Ltd Report on FCC Compliance RD0565 Rev 4.1 Page 21 of 38 04-08-23 Fig…

9. Answers to the FCC part 15 section 15.247 Clause (f): The RFI-9256 OEM module is not a hybrid system, within the context of clause (f). It operates in frequency-hopping mode, with the baseband signal being GMSK modulated. No spreading code is used on the baseband signal prior to frequency-hopping. Clause (g): The RFI-9256 OEM operates in fixed frames, Time-Division Duplex mode. It is thus not designed to operate in continuous transmission mode. The selected frame time is the channel dwell time. All channels are equiprobable. Clause (h): The RFI-9256 OEM does not provide multi-user detection for the purpose of channel avoidance, such as adaptive frequency hopping patterns with e.g. channel exclusion. Blocked channels may result in loss of data. The lost data is repeated via ARQ. The RFI-9256 operates in a master/slave mode. Masters transmit according to the selected hopping sequence number. Frequency-hopping of co-located masters is pseudo-random in nature and is not coordinated in a manner to select mutually exclusive channels.

Please refer to CD Rev 1.0.3, under the directory “/BNC Connector”, for detailed views of the transmitter section: ∑ “FCC_FERRULE.PDF” is the mechanical drawing for the ferrule and contains all required specifications for its manufacture; ∑ “FCC_BNC_CONNECTOR.PDF “is the mechanical drawing for the matching BNC connector and also contains all required specifications for its manufacture. The transmitter is fitted with a standard right-angle shielded PCB-mount female BNC connector. This connector is modified by way of fitting a shroud over its mating end (refer to “FCC_FERRULE.PDF”). The shroud is then screwed on and permanent secured with thread locking adhesive (Loctite). There are no provisions for gripping facilities on the shroud, thus separation of the two parts is near impossible. This modification turns a “standard BNC” connector into a non-standard “unique BNC” connector. The shroud fitted over the transmitter board connector limits the diameter of a connector that this connector can accept, thus a “BNC connector” with a smaller overall diameter is required. A non-modified (standard) BNC antenna cable connector can not be connected to the transmitter board. The supplied antenna coaxial cable is fitted with a modified male BNC (modified connector as shown in “FCC_BNC_CONNECTOR.PDF”), which allows mating of the two connectors: transmitter and antenna. 4.6 Label 6.
