NOTE: 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 interference that may cause undesired operation. To comply with RF exposure requirements, Please maintain 20cm separation from the device. NOTE: Changes or modifications made by the user and not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. 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 in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, 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 reception, 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: • Reorient or relocate the receiving antenna. • Increase the separation between the equipment and receiver. • Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. • Consult the dealer or an experienced radio/TV technician for help NOTE: This device complies with Industry Canada License-exempt RSS standard(s). Operation is subject to the following two conditions: 1. This device may not cause interference, and 2. This device must accept any interference, including interference that may cause undesired operation of the device. Le présent appareil est conforme aux CNR d’Industrie Canada applicables aux appareils radio exempts de licence. L’exploitation est autorisée aux deux conditions suivantes: 1. l’appareil ne doit pas produire de brouillage, et 2. l’utilisateur de l’appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est susceptible d’en compromettre le fonctionnement.

Page 1 of 1 Request for Confidentiality Date: June 22, 2020 Subject: Confidentiality Request for: FCC ID: 2AVOR-RAIS IC: NA Pursuant to FCC 47 CFR 0.457(d) and 0.459 and IC RSP-100, Section 9.4, the applicant requests that a part of the subject FCC application be held confidential. Type of Confidentiality Requested Exhibit ☐ Short Term ☒ Permanent ☐ Not Provided Block Diagrams ☐ Short Term ☐ Not Provided External Photos ☐ Short Term ☐ Permanent ☐ Not Provided Internal Photos ☐ Short Term ☒ Permanent ☐ Not Provided Operation Description/Theory of Operation ☐ Short Term ☐ Permanent ☒ Not Provided Parts List & Placement/BOM ☐ Short Term ☐ Permanent ☒ Not Provided Tune-Up Procedure ☐ Short Term ☒ Permanent ☐ Not Provided Schematics ☐ Short Term ☐ Not Provided Test Setup Photos ☐ Short Term ☐ Permanent ☐ Not Provided User’s Manual The above-mentioned company has spent substantial effort in developing this product and it is one of the first of its kind in industry. Having the subject information easily available to "competition" would negate the advantage they have achieved by developing this product. Not protecting the details of the design will result in financial hardship. Permanent Confidentiality: The applicant requests the exhibits listed above as permanently confidential be permanently withheld from public review due to materials that contain trade secrets and proprietary information not customarily released to the public. Short-Term Confidentiality (if applicable): Not applicable The applicant requests the exhibits selected above as short term confidential be withheld from public view for a period of 180 days from the date of the Grant of Equipment Authorization and prior to marketing. This is to avoid premature release of sensitive information prior to marketing or release of the product to the public. Applicant is also aware that they are responsible to notify ACB in the event information regarding the product or the product is made available to the public before the requested period has expired. ACB will then release the documents listed above for public disclosure pursuant to FCC Public Notice DA 04- 1705. NOTE for Industry Canada Applications: IC currently only distinguishes Permanent Confidentiality exhibits as shown above. Short Term confidentiality is not considered Provided to IC applications Sincerely, By: __________________________ Nic Johnson, Technical Manager, NCEE Labs
