Columbia, MD 21046 Re: Extended Frequency Justification on FCC ID: AIERIT41-117 To whom it may concern: The RQX-117NX two-way callbox radio is designed to operate in the frequency band 150-174 MHz. To aid equipment authorization in other countries within ITU regions 1, 2 or 3 which accept the United States FCC Grant for certification, Ritron is requesting that the FCC lists the frequencies 150-174 MHz under FCC Rule Parts 90 on the FCC Grant. This product is also intended for Federal end users. For the FCC’s Rule Part 90 applications, this radio is used in systems by OEM systems integrators as indicated in the table below. Equipment programming is the responsibility of Authorized Service Personnel. Also, the radio complies with 47 CFR Part 90.203(e) in that the operator cannot directly program the transmit frequencies using the normally accessible external controls. Per the FCC’s KDB634817 guidance, “as an alternative to listing the exact frequencies, we acknowledge that it’s a violation of the FCC Rules if this device operates on unauthorized frequencies.” Frequency Range (MHz) Part 90 Federal Customers/ Not Part 90 150.0000 - 150.8000 x 150.8000 - 156.2475 x 156.2475 - 157.1875 x 157.1875 - 161.5750 x 161.5750 - 161.7750 x 161.7750 - 161.9625 x 161.9625 - 162.0375 x 162.0375 - 173.4000 x 173.4000 - 174.0000 x Sincerely, Sam L.

TYPE OF EXHIBIT: RF EXPOSURE EVALUATION FCC PART: 1.1310 MANUFACTURER: RITRON, Inc. MODEL: RQX-117NX TYPE OF UNIT: VHF FM Callbox 2-Way Radio FCC ID: AIERIT41-117 DATE: Nov 25, 2015 PROCEDURE: Because this product is used as a mobile device, an RF evaluation was done. The RF evaluation entailed testing the unit on RITRON’S 3-meter range to determine EIRP and then calculating the minimum safe distance from the antenna necessary to ensure compliance with the appropriate RF exposure limits. 1. The measurement for effective radiated power was taken at the RITRON, Inc. 3-meter test site, details of which are on file with the FCC and Industry Canada. 2. The DUT was aligned for transmitter operation on lower, middle and upper band edge frequencies at the 2.5 Watt output power rating of the RQX- 117NX. The unit’s internal antenna radiation will be measured. 3. The RQX-117NX was placed on a turntable and rotated to the maximum radiation point as picked up by the log periodic antenna. The height of the measurement log periodic antenna’s height was varied to find maximum field strength. 4. In performing the substitution method of measurement an adjustable dipole, was substituted for the DUT at the RQX-117NX previous location. An RF signal generator was set for the frequency of the DUT with the level at the substitution antenna noted. The height of the receiving antenna was adjusted for maximum signal strength. All field strength measurements were made with the Advantest R3265A Spectrum Analyzer and log periodic antenna. TYPE OF EXHIBIT: RF EXPOSURE EVALUATION FCC PART: 1.1310 MANUFACTURER: RITRON, Inc. MODEL: RQX-117NX TYPE OF UNIT: VHF FM Callbox 2-Way Radio FCC ID: AIERIT41-117 DATE: Nov 25, 2015 EQUATIONS FOR EIRP: The effective radiated power (ERP) is: ERP(dBm) = Prad(dBm) + Pgen(dBm) – Psub(dBm) + Ga(dBd) Where: Prad is the power level of the radio’s emission at the receiving antenna output. Pgen is the RF signal generator level at the substitution antenna input. Psub is the power level of the substitution antenna emission at the receiving antenna output. Ga(dBd) is the gain of the substitution antenna over a dipole (0 dB). The ERP is converted to watts from dBm by: ERP(watts) = antilog 10 ((ERP(dBm) – 30)/10) And finally, ERP is converted to EIRP (isotropic radiator) by: EIRP = 1.64 ERP TYPE OF EXHIBIT: RF EXPOSURE EVALUATION FCC PART: 1.1310 MANUFACTURER: RITRON, Inc. MODEL: RQX-117NX TYPE OF UNIT: VHF FM Callbox 2-Way Radio FCC ID: AIERIT41-117 DATE: Nov 25, 2015 RESULTS FOR EIRP: DETERMINING MPE DISTANCE: EIRP = 1.64 (ERP/2) Power density is related to EIRP: S(W/m 2 ) = EIRP(W)/4r 2 where r is the distance from the source in meters. Rearranging for distance: _________ r = (EIRP/4S) The MPE (maximum permissible exposure) for a device operating in a general/uncontrolled exposure environment is 0.2 mW/cm 2 . Converting to W/m 2 , the limit becomes 2 W/m 2 . The MPE limit is substituted for S and EIRP is entered in the above equation. A 50% transmitter duty cycle is used for the two way radio.

MODEL: RQX-117NX TYPE OF UNIT: VHF FM Callbox 2-Way Radio FCC ID: AIERIT41-117 DATE: Nov 25, 2015 WARNING STATEMENT: The following statement appears in the Users Manual: PLEASE NOTE THE FOLLOWING WITH REGARD TO RF EXPOSURE FOR THIS PRODUCT, EXPOSURE TO RADIO FREQUENCY ENERGY: This product generates radio frequency (RF) energy when the PTT button on the front of the unit is depressed. This product has been evaluated for compliance with the maximum permissible exposure limits for RF energy at the maximum power rating of the unit. At the 20 cm (8 inches) minimum expected separation distance and greater, the maximum RF exposure is at or below the General Population/Uncontrolled limits. Operator should stay at least 20 cm (8 inches) from call box. External antennas have not been tested for compliance and may or may not meet the exposure limits at the distances given. Higher gain antennas are capable of generating higher fields in the strongest part of their field and would, therefore, require a greater separation from the antenna. They can be mounted higher than the call box which will increase the operator’s separation from the antenna. This product is not to be used by the general public in an uncontrolled environment unless compliance with the Uncontrolled/General Population limits for RF exposure can be assured. To limit exposure to RF energy to levels below the limit, please observe the following: • DO NOT activate the transmitter when not actually wishing to transmit. • When transmitting, make certain that the distance limits for the particular model in use are observed. • DO NOT allow children to operate the radio. When used as directed, this series of radios is designed to comply with the FCC’s RF exposure limits for “Uncontrolled/General Population”. In addition, they are designed to comply with the following Standards and Guidelines: • United States Federal Communications Commission, Code of Federal Regulations; 47 CFR §§ 2 sub-part J. • American National Standards Institute (ANSI) / Institute of Electrical and Electronic Engineers (IEEE) C95. 1-1992. • Institute of Electrical and Electronic Engineers (IEEE) C95.1-1999 Edition.

MODEL: RQX-117NX TYPE OF UNIT: VHF FM/NXDN 2-way callbox FCC ID: AIERIT41-117 DATE: October 13, 2015 PROCEDURE: 1. The RQX-117NX was aligned for transmitter operation at three frequencies across the operating band. RF power output using an external 12 VDC was measured. The unit is capable of being powered by 3 D cells or an external 8 to 12 volt battery. The controller senses the battery voltage and adjusts to either low power (nominal 800 mW) or high power (nominal 2.5 W). Battery voltage ranges are as follows: 3 D cells: 4.5 to 3.3 v 12 v external battery: 12 v to 8 v 2. Power was supplied to the RQX-117NX by a PS3010U Power Supply. The RQX- 117NX was connected to a HP8920A Test Set through an SMB test port connector used to measure the RF carrier power. The input to the Test Set provides a resistive 50-ohm termination at the frequencies and power levels used for this test. 3. The voltage (V tx) and current (I tx) into the power supply lead of the RF Power Module was measured by an HP3466A Digital Multimeter for the various supply voltages. 4. As can be seen in the table the 3 D cells yields a nominal 800 mW output while the external 12 VDC can yield up to 2.5 Watts output power. 6 TYPE OF EXHIBIT: RADIO FREQUENCY OUTPUT POWER FCC PART: 2.1046(a) MANUFACTURER: RITRON, Inc.

The audio output of the HP8920 was swept in frequency from 200 Hz to 6 kHz and was injected in the AUX_IN input. 3. The modulated signal was demodulated by an HP8920A and the audio output signal was sent to an HP8560E spectrum analyzer to obtain a larger dynamic range of measurement. 4. The overall FM deviation is plotted relative to deviation at 1 kHz. The TIA-603-C limits are plotted above and below the response curve.
