All specifications are subject to change without notice. This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection 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 instruc-

tions, 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 recep-

tion, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

1. Reorient or relocate the receiving antenna. 2. Increase the separation between the equipment and receiver. 3. Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. 4. 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 interfer-

ence that may cause undesired operation. Caution: Any changes or modifications not expressly approved by the party responsible for compliance could void the users authority to operate this equipment. RF Exposure The antennas used for this transmitter must be installed to provide a separa-

tion distance of at least 20 cm from all persons and must not be co-located or operating in conjunction with any other antenna or transmitter. miniPCIe Slot Pin Assignment FCC Statement MiniPCIe slot ( 9.9mm height mini-PCIe slot) Top side Bottom side PCIE_RST

COMPEX Compex Systems Pte Ltd Non-SDR (Software Defined Radio) Cover Letter FCC ID: TK4WPJ419 Model No.: WPJ419, WPJ419HV, WPJ419LV Refer to KDB 442812 DO1 SDR apps Guide v02r03. The following six questions can be used for determining if a radio can elect to be or must be an SDR. 1. Can the RF parameters of the device be altered through software?

Yes - go to 2. No, not an SDR 2. Can third parties not permitted by the Commission through specific filings modify, configure, or load different software, or make configuration settings to operate the device or host hardware radio frequency parameters (frequency range, modulation type, maximum output power or other radio parameters) in any other way than granted (or expected to be granted)?

Yes, must be an SDR. No - go to 3. 3. Is the device capable of operating in any other in any other way than granted, or will be, granted?

Yes, - go to 4. No - go to 5. 4. ls this a Part 15 client Device as defined in Section 15.202 (as opposed to a master device)?

Yes, qualifies as a part 15 client devices - go to 5. No, must be an SDR. YES or NO 5. Does the manufacturer elect SDR?

Yes, elects to be an SDR. No, Not an SDR Conclusion:

According to the above questions reply, we can confirm this device (Product Description:

Wireless Access Point) must be a non-SDR. Name: Yaw Thiam Teng Title: R&D Software Manager Email: tt_yaw@compex.com.sg Date: 2022/06/15 Non-SDR (Software Defined Radio) Cover Letter Page 1 of1
