Chongqing Guohe Electronic Technology Co.,Ltd. 15F, Unit 1, Building 12, No.2 Gangan 2nd Road, Jiangbei District, Chongqing, China Date: 2024-01-29 Declaration Letter FEDERAL COMMUNICATIONS COMMISSION Authorization and Evaluation Division 7435 Oakland Mills Road Columbia, MD 21046 Subject: Declaration of compliance to the requirements of §15.121 FCC ID: 2BEJV-PMR-171 Dear Sir/Madam, We declare that, this scanning receiver is incapable of operating (tuning), or readily being altered by the users to operate, within the frequency bands allocated to the Cellular Radiotelephone Service in part 22 of this chapter (cellular telephone bands). This device will not be able to receive transmissions in the cellular telephone bands by means of clipping the leads of, or installing, a simple component such as a diode, resistor or jumper wire; replacing a plug-in semiconductor chip; or programming a semiconductor chip using special access codes or an external device, such as a personal computer. This device is also incapable of converting digital cellular communication transmissions to analog voice audio. This device is designed so that the tuning, control and filtering circuitry is inaccessible. Any attempts to modify the equipment to receive transmissions from the Cellular Radiotelephone Service will render the receiver inoperable.This scanning receiver rejects any signals from the Cellular Radiotelephone Service frequency bands that are 38 dB or lower based upon a 12 dB SINAD measurement. We are aware that the modification of this device to receive transmissions from Cellular Radiotelephone Service frequency bands will be considered to constitute manufacture of such equipment. This includes any individual, individuals, entity or organization that modifies one or more scanners. Any modification to receive transmissions from the Cellular Radiotelephone Service frequency bands voids the certification of the scanning receiver, regardless of the date of manufacture of the original unit. Sincerely Yours, Signature: ___________________________ Contact Person: Yongliang Chen
