This equipment generate, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, 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 interference 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 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. 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. FCC Caution: Any changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate this equipment. RF exposure warning This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment must not be collocated or operating in conjunction with any other antenna or transmitter.

Test Limit The maximum permissible time of occupancy is 400ms within a period of 400ms multiplied by the number of hopping channels employed. 7.6.2. Test Procedure Used ANSI C63.10-2009 - Section 7.7.4 7.6.3. Test Settitng 1. Span = zero span, centered on a hopping channel. 2. RBW = 1MHz 3. VBW ≥ RBW 4. Sweep time = as necessary to capture the entire dwell time per hopping channel 5. Detector = Peak 6. Trace mode = max hold If possible, use the marker-delta function to determine the dwell time. If this value varies with different modes of operation (data rate, modulation format, etc.), repeat this test for each variation. An oscilloscope may be used instead of a spectrum analyzer. The EUT shall show compliance with the appropriate regulatory limit for the number of hopping channels. A plot of the data shall be included in the test report.

Test Limit The maximum permissible emission level is 20dBc. Any emissions were lying outside of the emission bandwidth and in authorized band edges to a field strength limit specified in Section 15.209 of the Title 47 CFR. 7.7.2. Test Procedure Used ANSI C63.10-2009 - Section 7.7.9 7.7.3. Test Setting 1. Span = wide enough to capture the peak level of the emission operating on the channel closest to the band edge, as well as any modulation products which fall outside of the authorized band of operation. 2. RBW ≥ 1% of spectrum analyzer display span 3. VBW ≥ RBW 4. Detector = peak 5. Sweep time = auto couple 6. Trace mode = max hold 7. Trace was allowed to stabilize Allow the trace to stabilize. Set the marker on the emission at the band edge, or on the highest modulation product outside of the band, if this level is greater than that at the band edge. Enable the marker-delta function, than use the marker-to-peak function to move the marker to the peak of the in-band emission. Report No.: 1504RSU01101 FCC ID: Y4N-IBO Page Number: 41 of 72 7.7.4.
