RF Energy Exposure Guide for MeteorComm Two-Way Radios Installed in Vehicles or at Fixed Sites IMPORTANT BEFORE USING YOUR MOBILE 2-WAY RADIO, READ THIS GUIDE WHICH CONTAINS IMPORTANT RF ENERGY AWARENESS AND CONTROL INFORMATION AND OPERATIONAL INSTRUCTIONS TO ENSURE COMPLIANCE WITH THE FCC’S RF EXPOSURE GUIDELINES. IMPORTANT RETAIN THIS GUIDE AT THE LOCATION OF THE RADIO INSTALLATION. RF Energy Exposure Awareness and Control Information, and Operational Instructions for FCC Occupational Use Requirements NOTICE: This radio is intended for use in occupational/controlled conditions, where users have full knowledge of their exposure and can exercise control over their exposure to meet FCC limits. This radio device is NOT authorized for general population, consumer, or any other use. 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 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, 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 safe 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, manufacturers also recommend specific operating instructions to users of 2-way radios. These instructions are important because they inform users about RF energy exposure and provide simple procedures on how to control it. Please refer to the following Web sites for more information on what RF energy exposure is and how to control your exposure to assure compliance with established RF exposure limits. http://www.fcc.gov/oet/rfsafety/rf-faqs.html http://www.osha.gov/SLTC/radiofrequencyradiation/index.html MCC RF Energy Exposure Guide 1 2/14/2007 Federal Communication Commission Regulations The FCC rules require manufacturers to comply with the FCC RF energy exposure limits for mobile 2-way radios before they can be marketed in the U.S. When 2-way radios are used as a consequence of employment, the FCC requires users to be fully aware of and able to control their exposure to meet occupational requirements. Exposure awareness can be facilitated by the use of a label directing users to specific user awareness information. Your MeteorComm (MCC) 2-way radio has an RF exposure product label. Also, your MCC user manual, as well as this RF Energy Exposure Guide guide, includes information and operating instructions required to control your RF exposure and to satisfy compliance requirements. Compliance with RF Exposure Standard Your MCC two-way radio is designed and tested to comply with a number of national and international standards and guidelines (listed below) regarding human exposure to radio frequency electromagnetic energy. This radio complies with the IEEE and ICNIRP exposure limits for occupational/controlled RF exposure environment at duty factors of up to 50% talk-50% listen and is authorized by the FCC for occupational use. In terms of measuring RF energy for compliance with the FCC exposure guidelines, your radio antenna radiates measurable RF energy only while it is transmitting (during talking), not when it is receiving (listening) or in standby mode. Your MCC two-way radio complies with the following RF energy exposure standards and guidelines: • United States Federal Communications Commission, Code of Federal Regulations; 47CFR part 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 MCC RF Energy Exposure Guide 2 2/14/2007 RF Exposure Compliance and Control Guidelines and Operating Instructions for Vehicular Installations To control exposure to yourself and others and to ensure compliance with occupational/controlled environment exposure limits, always adhere to the following procedures. 1. Guidelines: • These user awareness instructions should accompany the device or vehicle that it is installed in when transferred to other users. • Do not use this device if the operational requirements described herein are not met. 2. Operator Instructions: • For voice operation, transmit no more than the rated duty factor of 50% of the time. To transmit (talk), push the Push-To-Talk (PTT) button. To receive calls, release the PTT button. Transmitting 50% of the time, or less, is important because this radio generates measurable RF energy exposure only when transmitting (in terms of measuring for standards compliance). • Be aware that a transmitter may operate automatically at any time when functioning as a data radio. People outside of the vehicle must maintain the recommended minimum lateral distance from the antennas at all times. It is the responsibility of the vehicle’s operator to keep bystanders beyond the minimum lateral distance from the antennas in order to comply with the FCC RF exposure limits for an uncontrolled/general population environment. • Transmit only when people outside the vehicle are at least the recommended minimum lateral distance away, as shown in Table 1, from a properly installed externally-mounted antenna. NOTE: Table 1 below lists the recommended lateral distances to be maintained between bystanders and approved, properly installed transmitting antennas (e.g., monopoles over a ground plane, or dipoles) in an uncontrolled…

The DDS contains a numerically controlled oscillator (NCO) that accumulates (integrates) carrier phase at a 230.4 MHz sample rate with a modulus of two Pi. The fixed part of the phase increment for the accumulator sets the carrier frequency of the NCO and a modulation increment added or subtracted from the fixed increment, at 384k samples per second, modulates the carrier phase relative to the fixed phase increment to produce phase shift keying (PSK) or frequency shift keying (FSK). The instantaneous phase samples output from the NCO are applied to a ROM look up table that outputs sinusoidal values. Finally, these values are applied to a 230.4 M sample/sec digital to analog converter (DAC). Analog filters farther along in the signal path remove DAC harmonic distortion and other spurii. 4-3 Meteor Communications Corporation FCC ID: BIB61201001 For the 39-50 MHz transmitter band, the DDS DAC output signal is generated directly on the assigned carrier frequency. For the 151-162 MHz transmitter band, the DDS outputs an intermediate frequency (I.F.) band from 61 to 68 MHz. With one exception, the MCC-6101 digital data modulation waveforms are all Gaussian- filtered frequency shift keying (GFSK). The modulation pre-filters have Gaussian spectral characteristics with linear phase response. They are designed according to the selected bit rate, peak deviation and the spectral limits imposed by the FCC masks. When the peak-to-peak frequency deviation equals half the bit rate, the modulation is called Gaussian Minimum Shift Keying (GMSK). For GFSK, the incoming data bits are converted to bipolar rectangular pulses with amplitude +1 or -1. These are then low pass filtered, amplitude scaled and interpolated to the modulation sample rate by the Gaussian filter. The result is added to the NCO carrier phase increment. One additional data modulation waveform is constant envelope binary phase shift keying (CEBPSK). In this case, the original data bits are converted to bipolar impulses rather than rectangular pulses. When applied to the NCO at a prescribed amplitude, in the same manner previously described, the NCO integrates the impulses to linearly advance or retard the carrier phase exactly 180 degrees over the duration of the bit. Voice modulation begins by digitizing the amplified microphone voice waveform. The samples are then passed through a digital pre-emphasis filter followed …

Meteor Communications Corporation FCC ID: BIB61201001 Exhibit 13 RF Exposure 13.1 Determination of Need for Routine Environmental Evaluation for RF Exposure per §2.1091(c) It is the view of MCC that the MCC-61201001 is not subject to routine environmental evaluation for RF exposure. While it is intended for use in Part 90 applications, it is not designed for use in the Specialized Mobile Radio Service. 13.2 RF Exposure Calculations The MCC-61201001 transmitter operates in three (3) frequency bands: 39-50 MHz, 151- 162 MHz, and 2412-2462 MHz. Per Figure 1 of OET Bulletin 65, the FCC limit for Maximum Permitted Exposure (MPE) in an Occupational/Controlled Exposure environment to the power densities, S: S = 1mW/cm 2 for the frequency range of 30-300 MHz, S = f/300 mW/cm 2 for the frequency range of 300-1500 MHz, S = 5mW/cm 2 for the frequency range of 1500-3000 MHz, where f is expressed in MHz. The FCC power density limits for each of the subject transmit bands are expressed below. Frequency Band (MHz) MPE Power Density Limit (mW/cm^2) 39 - 50 1.0 151 - 1621.0 896 - 9013.0 935 - 9403.1 2412 - 24625.0 Note: A discussion of this subject as pertains to 896-901MHz and 935-940MHz is included here as the RF Exposure Information page from the Operators Manual will be common to all MCC-6100 variants and some versions of the 6100 family include these bands. The minimum separation required between a human and an antenna connected to an active antenna can be determined by use of the power density expression: R PG S π4 = 13-1 Meteor Communications Corporation FCC ID: BIB61201001 Where: S = power density in mW/cm 2 P = RF power into the antenna in mW G = antenna gain (unitless, linear) R = separation/distance between antenna and point of interest in cm Solved for R, the formula becomes: S PG R π4 = The charts below shows the maximum transmit power levels, duty cycles, maximum power densities and R, the calculated minimum human separation for each band.
