2020-11-11 Federal Communications Commission Authorization and Evaluation Division, 7435 Oakland Mills Road Columbia, MD 21046 USA Re: FCC ID: 2ASNSH777 Gentlemen: The scanner receiver equipment meets the requirements of the FCC Rules, 15.121(a) and (b). Compliance is achieved through the following methods: The scanner receiver in this equipment is incapable of tuning, or readily being altered, by the User to operate within the frequency bands allocated to the Domestic Public Cellular Telecommunications Service in Part 22. Blocking of the cellular frequencies is implemented in the firmware of the unit’s main control central processing unit (CPU). Coverage of 824 - 849 MHz and 869 - 894 MHz is completely blocked, since it is done in the microprocessor, and cannot be re-enabled by any user-accessible procedure, including diode, resistor, or jumper changes, nor by connection of any external device such as a personal computer, nor by installation of any “special” enabling semiconductor device. The scanning receiver is designed so that the tuning, control and filtering circuitry is inaccessible. The scanning receiver is reject any signals from the Cellular Radiotelephone Service frequency bands that are 38 dB or lower based upon a 12 dB SINAD measurement.

Head Date of measurement Return-loss (dB) Delta (%) Real Impedance (ohm) Delta (ohm) Imaginary impedance (ohm) Delta (ohm) 2018-02-23 -21.1 59.6 -0.2 2019-02-15 -21.8 -3.32 59.1 0.5 -0.8 0.6 2019-01-22 -21.8 -3.32 58.8 0.8 -0.5 0.3 The return loss is <-20dB, within 20% of prior calibration; the impedance is within 5ohm of prior calibration. Therefore the verification result should support extended calibration.
