                                The applicant has been cautioned as to the following:

15.21 Information to User

The user’s manual or instruction manual for an intentional radiator shall caution the user that changes or modifications not
expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.

15.27(a) Special Accessories

Equipment marketed to a consumer must be capable of complying with the necessary regulations in the configuration in
which the equipment is marketed. Where special accessories, such as shielded cables and/or special connectors are
required to enable an unintentional or intentional radiator to comply with the emission limits in this part, the equipment
must be marketed with, i.e. shipped and sold with, those special accessories. However, in lieu of shipping or packaging
the special accessories with the unintentional or intentional radiator the responsible part may employ other methods of
ensuring that the special accessories are provided to the consumer, without an additional charge.

Information detailing any alternative method used to supply the special accessories for a grant of equipment authorization
or retained in the verification records, as appropriate. The party responsible for the equipment, as detailed in § 2.909 of
this chapter, shall ensure that these special accessories are provided with the equipment. The instruction manual for such
devices shall include appropriate instructions on the first page of text concerned with the installation of the device that
these special accessories must be used with the device. It is the responsibility of the user to use the needed special
accessories supplied with the equipment.

Standard Test Conditions Engineering Practices

Except as noted herein, the following conditions and procedures were observed during the testing:

In accordance with ANSI C63.10-2013 and unless otherwise indicated in the specific measurement results, the ambient
temperature of the actual EUT was maintained within the range of 10° to 40°C (50° to 104°F), unless the particular
equipment requirements specified testing over a different temperature range. Also, unless otherwise indicated, the
humidity levels were in the range of 10% to 90% relative humidity.

Measurement results, unless otherwise noted, are worst-case measurements.

Test Date: 9/12/17

                                                    Test Procedure

The EUT was tested in an anechoic chamber at a distance of 1 meter from the receiving loop antenna and characterized
to the 30 meter limit(40log (1m/30m) A spectrum analyzer was used to verify that the EUT met the requirements for
Fundamental Field Strength. The antenna correction and distance correction factors were summed with the quasi-peak
measurement to ensure accurate readings were obtained. The following table indicates the highest emission in each of
the indicated bands. Measurements were made with an amplified loop antenna and converted to field strength.

The EUT was placed in an environmental test chamber and a frequency counter was utilized to verify that the frequency
stability met the requirement for frequency stability across the temperature range from -20°C to +50°C. A variable DC
power supply was used to vary the voltage from 85% to 115% of the rated voltage.

Radiated Emissions

Test Date: 9/20/17

                                                  Test Procedure

The EUT was tested in a semi-anechoic chamber at a distance of 3 meters from the receiving antenna. A spectrum
analyzer was used to verify that the UUT met the requirements for Radiated Emissions. The spectrum was examined from
9kHz to 1 GHz those emissions closest to their respective limits have been documented below.

Powerline Conducted Emissions

                                                  Test Procedure
The EUT power cable connected to a LISN and the monitored output of the LISN was connected directly to a spectrum
analyzer. The conducted emissions from 150 kHz to 30 MHz were monitored and compared to the specification limits. The
average measurements were the worst case and are recorded in the tables below.

99% Occupied Bandwidth
Engineer: Alex Macon
Test Date: 9/12/17

                                                  Test Procedure

The EUT was tested on an anechoic chamber at a distance of 1 meter from the receiving loop antenna. A spectrum
analyzer was used to measure the 99% occupied bandwidth.
