Rule Part 15.21: The users manual or instruction manual for an intentional or unintentional radiator shall caution the user that changes or modifications not expressly approved by the party responsibl e for compliance could void the user's authority to operate the equipment. Note: This equipment has been tested and found to comply with t he limits for a Class B digital NOTE: This equipment has been tested and found to comply with t he limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protecti on 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 in structions, may cause harmful interference to radio communications. However , there is no guarantee that interference will not occur in a p articular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by t urning 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 fr om that to which the receiver is connected. Consult the dealer or an experienced radio/TV technician for h elp How to Install 2) After approximately 5 seconds, thereceiver will display a logo and thereceiver's default number "001" 3) To change to a number that does not overlap with otherreceivers, press the ▲ and ▼ buttons on the receiver to change the number.(Press and hold the ▲ and ▼ buttons to change quickly.) 1) Connect the receiver to the USB porton your PC Connect to the USB port

The following procedure shall be used for measuring this bandwidth: a. Set RBW = 100 kHz. b. Set the video bandwidth (VBW) ≥ 3 × RBW c. Detector = Peak. d. Trace mode = max hold. e. Sweep = auto couple. f. Allow the trace to stabilize g. Measure the maximum width of the emission that is constrained by the frequencies associated with the two outermost amplitude points (upper and lower frequencies) that are attenuated by 6 dB relative to the maximum level measured in the fundamental emission. Note: The automatic bandwidth measurement capability of a spectrum analyzer or EMI receiver may be employed if it implements the functionality described above.

Set RBW = 300 kHz (approximately 1% of the emission bandwidth). b. Set the video bandwidth (VBW) = 1000 KHz (VBW > RBW) c. Detector = Peak. d. Trace mode = max hold. e. Sweep = auto couple. f. Allow the trace to stabilize g. Measure the maximum width of the emission that is 26 dB down from the maximum of the emission. Compare this with the RBW setting of the analyzer. Readjust RBW and repeat measurement as needed until the RBW/EBW ratio is approximately 1%. Note: The automatic bandwidth measurement capability of a spectrum analyzer o…
