19 Morris Avenue, Building 128 Brooklyn, NY 11205 United States Monday, April 13, 2020 Attention: Application Examiner RE: Request for Confidentiality Applicant: Waverly Labs Inc FCC ID: 2AN4B –AMBASSADORI1 T o Whom It May Concern: Request is hereby submitted by Waverly Labs to withhold permanently from public review certain portions of this application for equipment certification. This request for confidentiality is made pursuant to 47 CFR 0.457(d) & 0.459 of the FCC Rules. In particular, the following sections of the application are to be kept permanently confidential: • Schematics • Detailed Block diagrams • Detailed Operational/Functional Description Rationale for request for confidentiality: Waverly Labs Inc has invested considerable time and materials in research and development to produce the referenced product. Disclosure of the 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significant competitive advantages in developing similar products, but would also disclose successful implementation of unpublished, leading edge technology developed by us. Sincerely, Sergio Del Río, VP of Product

Analysis Report Report No.: 20030538HKG-001 The Equipment Under Test (EUT) is an Ambassador Interpreter Earpiece which operates at frequency range of 2402MHz to 2480MHz. When the EUT pairs with a smartphone apps with Bluetooth feature, up to 4 users can use the language translation function on the smartphone apps. Only one person can wear one EUT at a time. The EUT is designed for the right ear where the users will hear the translation. The Bluetooth feature in the EUT is operating in the frequency range from 2402MHz to 2480MHz (79 channels 1MHz channel spacing). The applicant declared that Bluetooth BLE is not used. The EUT is powered by an internal 3.7V rechargeable battery. The USB port is for charging internal battery purpose only According to the KDB 447498: Conducted Power = EIRP – antenna gain = 5dBm - 0.5dBi = 4.5dBm = 2.82 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 above conducted output power is well below the SAR Exclusion threshold level, so the EUT is considered to comply with SAR requirement without testing.

Intertek Report No: 20030538HKG-001 Page 3 of 26 SUMMARY OF TEST RESULT Test Specification Reference Results Transmitter Power Line Conducted Emissions 15.207 / RSS-Gen 8.8 Pass Radiated Emission Radiated Emission on the Bandedge 15.249, 15.209 / RSS-210 B.10, RSS-210 4.4 Pass Radiated Emission in Restricted Bands 15.205 / RSS-210 4.1 Pass The equipment under test is found to be complying with the following standards: FCC Part 15, October 1, 2018 Edition RSS-210 Issue 10, December 2019 RSS-Gen Issue 5 Amendment 1, March 2019 Note: 1. The EUT uses a permanently attached antenna which, in accordance to section 15.203, is considered sufficient to comply with the pervisions of this section. 2. Pursuant to FCC part 15 Section 15.215(c), the 20 dB bandwidth of the emission was contained within the frequency band designated (mentioned as above) which the EUT operated. The effects, if any, from frequency sweeping, frequency hopping, other modulation techniques and frequency stability over excepted variations in temperature and supply voltage were considered.
