Each of four channels can be programmed to contain a unique set of operating frequencies. The DTXM Plus module is made up of two PC boards, an RF board and a control/loader board. These two boards are enclosed in a metal case with two connectors on one end; a 50 ohm BNC connector for connection to an antenna and a DB-15 sub-miniature connector for power and control input/output. In addition, the RF board is available as a stand-alone unit for system integrators. 1.2 MODEL IDENTIFICATION The DTXM has a part number in the form of “DTXM-A60-BCDEF” Where: A is the major frequency band designator: 1=VHF (136-174 MHz) 2=217-245 MHz 3=340-400 MHz 4=UHF (400-520 MHz) B is the sub-band designator: G=340-360 and 400-420 A=420-440 B=430-450 0=136-174, 217-245, 360-380, and 450-470 M=380-400 C=470-490 T=490-512 C is the connector designator: B=BNC connector M= MCX connector S=SMA connector D designates the channel bandwidth: S=6.25 kHz N=12.5 kHz W=25 kHz E designates the maximum power level: 3=3 watts 6=6 watts 9=10 watts F designates the regulator option I=Internal regulator (10-16 VDC operation with regulated RF power amplifier) D=No regulator (7.5 VDC operation) L=RF PA is unregulated, but the remainder of the modem is regulated (10-watt versions) Example: A DTXM-160-OBN6I would be a VHF module for operation between 136 and 174 MHz with a BNC RF connector, narrow (12.5 kHz channel spacing) IF bandwidth, 6 watts maximum output power, and an internal regulator to allow operation from 10 to 15 volts. 1.3 FCC/IC REGULATIONS 1.3.1 LICENSING For those frequency bands governed by FCC rules, the FCC requires that the radio owner obtain a station license for his radio before using the equipment to transmit, but does not require an operating license or permit. The station licensee is responsible for proper operation and maintenance of his radio equipment, and for ensuring that transmitter power, frequency and deviation are within the limits specified by the station license. This includes checking the transmitter frequency and deviation periodically using appropriate methods. Note also, that wideband operation (25/30 kHz channel bandwidth) may not be permitted. 1.3.2 PRODUCT CERTIFICATION The DTXM modules are certified by the FCC for operation in the United States and by Industry Canada for operation in Canada on certain frequency bands and sub-bands for transmission of either voice or data signals when aligned according to the alignment procedure for the proper bandwidth and when operated as a complete unit in the metal case. Operation of the RF board as a stand-alone unit or in combination with any other equipment, in any mode outside the alignment procedure, or with the clipper filter electronically disabled will require the filing of a new type acceptance application with the FCC by the user. 1.3.3 SAFETY STANDARDS-RF EXPOSURE RF ENERGY EXPOSURE AWARENESS AND CONTROL INFORMATION, AND OPERATIONAL INSTRUCTIONS FOR FCC OCCUPATIONAL USE REQUIREMENTS: BEFORE USING THIS 2-WAY RADIO, READ THIS IMPORTANT RF ENERGY AWARENESS AND CONTROL INFORMATION AND OPERATIONAL INSTRUCTIONS TO ENSURE COMPLIANCE WITH THE FCC’S AND IC’S RF EXPOSURE GUIDELINES. THIS DEVICE COMPLIES WITH PART 15 OF THE FCC RULES. OPERATION IS SUBJECT TO THE FOLLOWING TWO CONDITIONS: (1) THIS DEVICE MAY NOT CAUSE HARMFUL INTERFERENCE, AND (2) THIS DEVICE MUST ACCEPT ANY INTERFERENCE RECEIVED, INCLUDING INTERFERENCE THAT MAY CAUSE UNDESIRED OPERATION. NOTE: THE GRANTEE IS NOT RESPONSIBLE FOR ANY CHANGES OR MODIFICATIONS NOT EXPRESSLY APPROVED BY THE PARTY RESPONSIBLE FOR COMPLIANCE. SUCH MODIFICATIONS COULD VOID THE USER’S AUTHORITY TO OPERATE THE EQUIPMENT. NOTICE: This radio is intended for use in general population/uncontrolled conditions, where users do not have full knowledge of their exposure and cannot exercise control over their exposure to meet FCC/IC limits. This 2-way radio uses electromagnetic energy in the radio frequency (RF) spectrum to provide communications between two or more users over a distance. It uses radio frequency (RF) energy or radio waves to send and receive calls. RF energy is one form of electromagnetic energy. Other forms include, but are not limited to, electric power, sunlight and x-rays. RF energy, however, should not be confused with these other forms of electromagnetic energy, which when used improperly can cause biological damage. Very high levels of x-rays, for example, can damage tissues and genetic material. Experts in science, engineering, medicine, health and industry work with organizations to develop standards for exposure to RF energy. These standards provide recommended levels of RF exposure for both workers and the general public. These recommended RF exposure levels include substantial margins of protection. All 2-way radios marketed in North America are designed, manufactured and tested to ensure they meet government established RF exposure levels. In addition…

Columbia, MD 21046 Re: Extended Frequency Justification on FCC ID: AIERIT51-16006 To whom it may concern: The DTXM-160-0BN6I-NXDN, 6 watt, OEM radio transceiver was designed to operate in the frequency band 150-174 MHz. To aid equipment authorization in other countries which accept the United States FCC Grant for certification, Ritron is requesting that the FCC lists the frequencies 136-174 MHz under FCC Rule Parts 90 on the FCC Grant. 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 Grant Notes Emission Designator Part 90 136-150.8 x EF 10K0F3E, 4K00F1E, 8K30F1E, 4K00F1D, 8K30F1D, 4K00F7W, 8K30F7W 150.8 -156.2475 x EF “ 156.2475 - 157.1875 x EF “ 157.1875 - 161.575 x EF “ 161.575 - 161.775 x EF “ 161.775 - 161.9625 x EF “ 161.9625 - 162.0375 x EF “ 162.0375 – 173.4 x EF “ 173.4 -174 x EF “ Sincerely, Sam L.

MODEL: DTXM-160-0BN6I-NXDN TYPE OF UNIT: VHF Transceiver FCC ID: AIERIT51-16006 IC ID: 1084A-RIT5116006 DATE: November 18, 2020 DETERMINING MPE DISTANCE: Because this product is used as a mobile device, an RF calculation can be done to determine maximum permissible exposure. 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. Solving for distance as a function of transmitter power and required power density per area we get: _________ r = (EIRP/4S) The MPE (maximum permissible exposure) for a device operating in a occupational/controlled exposure environment is 1 mW/cm 2 . Converting to W/m 2 , the limit becomes 10 W/m 2 . The MPE limit is substituted for S and EIRP is entered in the above equation. With the maximum 6 watt unit transmitting into a unit gain quarter wave dipole on a ground plane we have an ERP of 6W. The EIRP will be 1.64 times that or 9.84 W. Also, the DTXM-160 must operate at 50% transmit duty cycle which gives a 4.92 W time averaged EIRP. Using that for the three test frequencies across the band the following minimum distances result when using the unity gain antenna.
