Box 370 Newberry, Florida 32669 USA Reference: Marketing and Professional Installation Required Attestation FCC ID: HCOAH373PSABC21A Marketing: The intended use is generally for industrial/commercial use and will not be sold to the general public. It will also not be sold through retail establishments or through mail order. It will be sold to OEM customers, qualified dealers and directly to commercial customers. Professional Installation: Since the equipment used in the above reference FCC ID has standard RF connectors, the system must be professionally installed. The installer shall be responsible for ensuring that the proper antenna is employed so that the limits specified in Part 1.1310 are not exceeded. It is intended for industry/commercial use. All the necessary instructions keeping our qualified dealers, commercial customers and professional installers clear of the necessity of professional installation are given in the product user manual. Professional installers will ensure that the equipment is installed following local regulations and safety codes. Professional System Design: Further, Dali Wireless, Inc., its partners and integrators will produce appropriate designs for proper equipment placement and settings. Professional RF design and modelling tools are always used to ensure the system operates within the desired coverage area at the appropriate signal levels. Permission is obtained from spectrum owners and deployment is typically coordinated with those spectrum owners. The equipment is setup, and typically centrally monitored, to ensure that it operates on intended frequencies and power levels and that it covers licensed areas and does not interfere with adjacent spectrum owners.

Exposure Evaluation airHost37™ 700-800-900 PS Tri-Band Medium Power airHost Unit FCCID: HCOHD373PSABC21A Date: Aug 1, 2020 Dali Wireless, Inc. 535 Middlefield Road, Suite 280 Menlo Park, CA 94025 http://www.daliwireless.com CONFIDENTIAL AND PROPRIETARY This document contains information proprietary to Dali Wireless. Any disclosure, use or duplication of this document or of any of the information contained herein for other than the specific purpose for which it was disclosed is expressly prohibited, except as Dali Wireless may otherwise agree to in writing. © Copyright 2020 Dali Wireless. All Rights Reserved Dali Wireless airHost37 700-800-900 Exposure Evaluation Page 2 of 2 RF Exposure Evaluation According to FCC Part 1.1307(b)(1), systems operating under the provisions of this section shall be operated in a manner that ensure that the public is not exposed to radio frequency energy level in excess of the Commission’s guidelines. More information on evaluating compliance with these limits can be found in the FCC's OST/OET Bulletin Number 65, “Evaluating Compliance with FCC-Specified Guidelines for Human Exposure to Radiofrequency Radiation”. In the Frequency Range of 300 to 1500 MHz, the maximum power density limit for the occupational / controlled exposures is 0.5 mW/cm 2 for an average time of 30 minutes. The antenna connected to the product is specific to the deployment. The worst case scenario occurs when using a very high gain outdoor/indoor antenna. However a typical indoor antenna is shown in the following example: The highest conducted output power is 37 dBm but we might need to back off to meet FCC Part 90.219 rules depending on the cable loss from hd37 remote unit to the antenna. The ERP can’t exceed 37dBm, so for a set output level of 30 dBm with an indoor antenna gain of 7 dBi, the EIRP is 37 dBm. The maximum power density safe exposure level for general population/uncontrolled exposure of 30 minutes for the frequency of 700MHz is 0.515 mW/cm 2 . Conducted Output Power (dBm) Max Antenna Gain (dBi) Max EIRP (mW) Power Density Limit Allowed (mW/cm²) Safe Distance (cm) 30 7 5012 0.515 28 RF Exposure Evaluation Distance Calculation 푑=√ (퐸퐼푅푃/4휋푆) Where: d = Distance to the center of radiation of the antenna (cm) for the allowable Power Density S = Allowable Power Density Limit (mW/cm 2 ) EIRP = Equivalent isotopically radiated power (mW) = 10 [TX Power (dBm) + Ant Gain (dBi)/10] As shown above, the minimum safe distance where the MPE limit is reached is 28 cm from a 7 dBi gain antenna for the 700MHz band. Using the same formula, the minimum safe distances are 27cm and 26 cm for the 800MHz band and the 900MHz band respectively assuming same antenna gain. If the antenna will be positioned closer to end users than 28 cm, then the installer must calculate the power back off required for a given installation using the formulas provided.
