Tech4home, Lda Attention: Certification reviewer RE: Request for Confidentiality 2ALB6-KMNMBLE04 To Whom It May Concern: Permanent Confidentiality [Complete this section if permanent confidentiality is requested] Request to withhold permanently from public review certain portions of the application for equipment certification for the referenced FCC identifiers. This request for confidentiality is made pursuant to 47 CFR 0.457(d) and 0.459 of the FCC Rules. In particular, the following sections of the application are to be kept permanently confidential: [Select one or more of items below, as appropriate] Schematics Block Diagrams Operational Description Tune-up Procedure Parts List Internal Photos (see note) Users Manual (see note) Note 1: Internal Photos may be held confidential 1) if the circuit board or internal components are not accessible to users. For example, it is acceptable if the circuit board is enclosed in epoxy. 2) Also, it is acceptable if the device is not accessible to the public, for example, a device mounted on the top of a large tower (or in a fenced enclosure) such that it is only serviceable by professional designated technicians under a Non-Disclosure Agreement (NDA). All sales for these devices must be under a NDA restricting the disclosure of the propriety information, including internal photos. User Manual may be held confidential only when the manual contains proprietary technical information intended for professional technicians obligated under a NDA. All sales and distribution of the user’s manual must be under a NDA that restricts the disclosure of the information. In the application cover letter requesting permanent confidentiality the following additional description and the NDA exhibit is required: 1. Describe in detail how internal photos and/or users manual information are controlled to prevent them from becoming public or disclosed to unauthorized persons. 2. Describe how public access is restricted for products serviceable by professional designated technicians. 3. A statement that all sales of the non-consumer device will be under a NDA to include third party sales and that the final user of the device is subject to the NDA. 4. Provide an example of the NDA between the grantee and a purchaser. The request for confidentiality must Note 2: For scanning receiver, the schematics, block diagrams, operational description, tune-up procedure, parts list and internal photos are always held permanently confidential. Short-term Confidentiality [Complete this section if short-term confidentiality is requested] Request to withhold from public review for a period of 180 days from the date of the Grant of Equipment Authorization and prior to marketing, certain portions of the application for equipment certification for the referenced FCC identifiers. This request for confidentiality is made pursuant to 47 CFR 0.457(d) and 0.459 of the FCC Rules. In particular, the following sections of the application are to be kept short-term confidential for a period above from the date of the grant [Select one or more of items below that are not selected in the list above, as appropriate] Schematics Block diagrams Operational Description Tune-up Procedure Parts List Test Setup Photos External Photos Internal Photos Users Manual Rationale for request for confidentiality: We have invested considerable time and materials in research and development to produce the referenced product. Permanent confidentiality: Disclosure of the permanently confidential portions of this application to competitors would not only give them significant competitive advantages in developing similar products, but would also disclose successful implementation of unpublished, leading edge technology developed by us. Short-term confidentiality: Disclosure of the short-term confidential portions of this application during the period of importation and/or distribution would reveal key aspects of proprietary technology to competitors and diminish the value of our investment in research and development. If you have questions or need further information, please contact the undersigned. Sincerely, _______________ Miguel Valente TQM September 17, 2020

Label Artwork and location Each equipment covered in the certification for equipment authorization shall bear a label listing as the following: 1) An FCC ID, which should be printed in the following format with legible lettering. Eight point type is acceptable. FCC ID: 2ALB6-KMNMBLE04 “FCC ID” - in capital letters on a single line. 2ALB6 - your grantee code as assigned by the FCC (may be three or five). KMNMBLE04 - up to 14 alphanumeric characters you select. Dash or hyphen (-) may be used. No spaces are allowed. 2) Label artwork and location Note 1: The label shall not be a stick-on paper label. The label on these products shall be permanently affixed to the product and shall be readily visible to the purchaser at the time of purchase. “Permanently affixed” means that the label is etched, engraved, stamped, silkscreened, indelibly printed, or otherwise permanently marked on a permanently attached part of the equipment or on a nameplate of metal, plastic, or other material fastened to the equipment by welding, riveting, or a permanent adhesive. The label must be designed to last the expected lifetime of the equipment in the environment in which the equipment may be operated and must not be readily detachable.

INTERTEK TESTING SERVICES RF Exposure The equipment under test (EUT) is a Remote Control with Bluetooth function operating in 2402-2480MHz. The EUT is powered by DC 3.0V(2*1.5V AAA batteries), For more detail information pls. refer to the user manual. Bluetooth Version: 5.0 BLE (Single Mode) Antenna Type: Integral antenna Modulation Type: GFSK Antenna Gain: 0dBi Max The nominal conducted output power specified: 4.0dBm (+/-2dB) The nominal radiated output power(e.i.r.p) specified: 4.0dBm (+/-2dB) According to the KDB 447498: The Maximum peak radiated emission for the EUT is 100.8 dBμV/m at 3m in the frequency 2402MHz The EIRP = [(FS*D) ^2 / 30] mW = 5.57dBm which is within the production variation. The Minimum peak radiated emission for the EUT is 98.1 dBμV/m at 3m in the frequency 2480MHz The EIRP = [(FS*D) ^2 / 30] mW = 2.87dBm which is within the production variation. The maximun conducted output power specified is 6.0dBm = 3.98mW The source- based time-averaging conducted output power = 3.98 * Duty factor mW (where Duty Factor≤1) = 3.98 mW The SAR Exclusion Threshold Level: = 3.0 * (min. test separation distance, mm) / sqrt(freq. in GHz) = 3.0 * 5 / sqrt (2.480) mW = 9.53 mW Since the source-based time-averaging conducted output power is well below the SAR low threshold level, so the EUT is considered to comply with SAR requirement without testing.
