Two Riverfront Plaza | Newark, NJ 07102-5490 Ben Botros, Project Manager Safety , Compliance and Quality Assurance Request for Confidentiality December 12, 2019 PCTP-19-F008 Federal Communication Commission Equipment Authorization Division / Application Processing Branch 7435 Oakland Mills Road Columbia, Maryland 21046 To whom it may concern; FCC ID: ACJ96NKX-TGW420 Type Filing: Original Application for UPCS Cordless Telephone Base Station Model Numbers: KX-TGW420 Request For Permanent Confidentiality In accordance with provisions of Sections §§0.457(d) and 0.459 of the Commission’s Rules and Section 552(b)(4) of the Freedom of Information Act, we request permanent confidentiality for exhibits, which contain: (1) Description of Electrical Circuitry; (2) Schematic Diagrams of Base Unit and RF Unit; and (3) Base Unit Block Diagram. Rationale: The transmitter is not user adjustable and does not have a Tune-Up Procedure. These exhibits contain proprietary, confidential and trade secrets material, which would not be routinely made available for public inspection and/or distribution would reveal key aspects of proprietary technology to competitors and diminish the value of our investment in research and development Request For Short-Term Confidentiality In accordance with FCC Public DA 04-1705, we request 180 day short-term confidentiality, starting from the from the issuance of equipment authorization date, for exhibits, which contain: (1) External Photographs of Base Unit and RF Unit; (2) Internal Photographs of Base Unit and RF Unit; (3) Test Setup Photographs; and (4) User Manual. Rationale: These exhibits contain pre-market information, which could give our competitors unfair advantage should this information be released before this product is actually introduced into the common marketplace. Sincerely yours, Ben Botros Project Manager Panasonic Corporation of North America Safety, Compliance and Quality Assurance

15 January 2020 To whom it may concern, Declarations FCC ID: ACJ96NKX-TGW420 I, the undersigned, hereby declare that 1. The device does not use the provisions of 47CFR 15.323 (c) (6), random waiting mechanism is not used in this system. 2. The provisions of 47CFR 15.323 (c) (10) and 47CFR 15.323 (c) (11) are not used to extend the range of spectrum occupied over space or time for the purpose of denying fair access to spectrum to other devices. 3. Only the handset will act as the initiating device, which will initiate the establishment of the duplex connection. 4. The device complies with the provisions of 47CFR 15.319(f). The device shall automatically discontinue transmission in case of either absence of information to transmit or operational failure. These provisions are not intended to preclude transmission of control and signaling information or use of repetitive codes used by certain digital technologies to complete frame or burst intervals. The following table explains the reaction of device in case of either absence of information to transmit or operational failure after a connection of its companion device is established. Circumstances Reaction of Base Unit 1 Switch-off companion device NA 2 On hook by companion device B 3 Switch-off device NA 4 On hook on device side A 5 Remove power from device A 6 Remove power from companion device B A – Connection is terminated and, transmission ceases. B – Connection is terminated but device transmits control or signaling information. C – Connection is terminated but companion device transmits control or signaling information. NA – Not applicable represents the device does not contain a hook switch or a power off switch. 5. M L of base unit declared by manufacturer are 30dBm. If you have questions or need further information, please contact the undersigned. Regards,

INTERTEK TESTING SERVICES FCC ID: ACJ96NKX-TGW420 RF exposure - 1 of 1 For Maximum Permissible Exposure (MPE) evaluation of the base unit, the maximum power density at 20 cm from this mobile transmitter shall be less than the General Population / Uncontrolled MPE limit in OET Bulletin 65 and meet the requirement listed in KDB447498. For the 1.9GHz Base Unit of tested model: KX-TGW420, the measured powers among all the measured channels were within its production tolerance: +16 dBm (Minimum) and +20.5 dBm (Maximum).The antenna gain of KX-TGW420 is 0 dBi = 1.00 (num gain) and its maximum source-based time-averaging duty factor is 20.8% (5/24 x100%). From these data and its operating configuration – Mobile device, the exposed power density at a distance (R) of 20cm from the center of radiation of the antenna can be calculated according to OET Bulletin 65 as follow: The Conducted Power = 20.5 dBm = 112.2 mW The Conducted Power source-based time-averaging output power = (112.2 * 0.208) mW = 23.34 mW The power density at 20cm = 23.34 *1.00/ 4πR 2 = 0.0047 mW cm -2 In the frequency range of 1,500 - 100,000MHz, the MPE limit is 1.0 mWcm -2 for general population and uncontrolled exposure. As the measured power density at 20cm from the transmitter is lower than the MPE limit, the compliance to the MPE limit can be ensured by indicating the minimum 20cm separation between the transmitter's radiating structures and body of the user or nearby persons. The following RF exposure statement is proposed to be included in the user manual: “ FCC RF Radiation Exposure Statement Caution: To maintain compliance with the FCC’s RF exposure guidelines, place the base unit at least 20cm from nearby persons.”
