Any HAWS product that includes the 0210000475 module should have the following on the label: “Contains: FCC ID: 2AUAN-12XXSM” “Contains: IC ID: 25359-12XXSM” Any HAWS product that contains the 0210000745 module should have the following warnings included in the user manual: “Maintain 20cm separation from antenna at all times.” Note: 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 when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense. This device contains licence-exempt transmitter(s)/receiver(s) that comply with Innovation, Science and Economic Development Canada’s licence-exempt RSS(s). Operation is subject to the following two conditions: 1. This device may not cause interference. 2. This device must accept any interference, including interference that may cause undesired operation of the device.

This module is certified for use by the FCC for use under Part 15.225 only. 2. Module is to be used within HAWS products only. The module is limited to use the on-board antenna only. No external antennas are to be used. 3. Haws is responsible for testing the module within any host to ensure compliance with all FCC Part 15 Subpart B rules, as well as any other applicable rules. 4. Module requires an input of 12VDC and 600mA of current. The module is using the ST Microelectronics CR95HF controller and is controlled via a pair of USART TX/RX lines. The module will be communicating with RFID tags using the ISO 15693 standard. 5. The on-board antenna design is shown in the attached schematic and board design files. 6. Module should be installed in such a way that user doesn’t access space within 20cm of the module under normal operation. This module is intended to be a low power device, not intended to be wearable. 7. A small ferrite, made of type 31 material is to be installed at the module end of cabling.

Sincerely, Sam Hong Senior Engineer - Compliance Manager Part 15 Unlicensed Single Modular Transmitter Approval Justification per 15.212 Requirement per 15.212 reference (i) The radio elements of the modular transmitter must have their own RF shielding. Shielding is provided by a metal cover over the circuitry. (ii) The modular transmitter must have buffered modulation/data inputs (if such inputs are provided. All modulation and data inputs are buffered by circuitry on the transmitter chip. (iii) The modular transmitter must have its own power supply regulation. Power supply regulation is provided by circuitry on the transmitter chip. (iv) The modular transmitter must comply with the antenna and transmission system requirements of §§ 15.203, 15.204(b) and 15.204(c). The antenna is permanently attached. (v) The modular transmitter must be tested in a stand-alone configuration, i.e., the module must not be inside another device during testing for compliance with Part 15 parameters. Testing was performed with the module extended outside of the host on a special extender board, as shown in the test setup photos. (vi) The modular transmitter must be equipped with either a permanently affixed label or must be capable of electronically displaying its FCC identification number. If the FCC ID is not visible when the module is installed inside another device, then the outside of the device into which the module is installed must also display a label referring to the enclosed module. Label to be screen printed on circuit board. See attached for details.

A copy of these instructions must be included in the application for equipment authorization. The module complies fully with the operating requirements of Part 15 section 15.225 as demonstrated in the test report exhibit. (viii) The modular transmitter must comply with any applicable RF exposure requirements in its final configuration. This module operates under Part 15 section 15.225, which is exempt from RF exposure evaluation owing to the very low operating power:
