The information provided in this document supersedes the general safety information contained in user guides published prior to July 2000. For information regarding radio use in a hazardous atmosphere please refer to the Factory Mutual (FM) Approval Manual Supplement or Instruction Card, which is included with radio models that offer this capability.RF Operational CharacteristicsYour radio contains a transmitter and a receiver. When it is ON, it receives and transmits radio frequency(RF) energy. The radio operates in the frequency range of 462 .5625 MHz to 4 62.7250 MHz a nd em ploys anal ogue mo dula tion techniq ues. Exposure To Radio Frequency EnergyYour Motorola radio is designed to comply with the following national and international standards and guidelines regarding exposure of human beings to radio frequency electromagnetic energy: • United States Federal Communications Commission, Code of Federal Regulations; 47 CFR 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 • National Council on Radiation Protection and Measurements (NCRP) of the United States, Report 86, 1986 • International Commission on Non-Ionizing Radiation Protection (ICNIRP) 1998 SAFETY AND GENERAL INFORMATION ii PRELIMINARY • Ministry of Health (Canada) Safety Code 6. Limits of Human Exposure to Radiofrequency Electromagnetic Fields in the Frequency Range from 3 kHz to 300 GHz, 1999 • Australian Communications Authority Radiocommunications (Electromagnetic Radiation - Human Exposure) Standard 1999 (applicable to wireless phones only) To assure optimal radio performance and make sure human exposure to radio frequency electromagnetic energy is within the guidelines set forth in the above standards, always adhere to the following procedures: PORTABLE RADIO OPERATION AND EME EXPOSUREAntenna CareUse only the supplied or an approved replacement antenna. Unauthorized antennas, modifications, or attachments could damage the radio and may violate FCC regulations.DO NOT hold the antenna when the radio is “IN USE.” Holding the antenna affects call quality and may cause the radio to operate at a higher power level than needed. Two-way Radio OperationWhen using your radio as a traditional two-way radio, hold the radio in a vertical position with the microphone one to two inches (2.5 to 5 cm) away from the lips. SAFETY AND GENERAL INFORMATION iii PRELIMINARY Body-worn OperationTo maintain compliance with FCC/Health Canada RF exposure guidelines, if you wear a radio on your body when transmitting, always place the radio in a Motorola supplied or approved clip, holder, holster, case, or body harness for this product. Use of non-Motorola-approved accessories may exceed FCC/Health Canada RF exposure guidelines. If you do not use a body-worn accessory, and are not using the radio held in the normal use position at the ear, ensure the radio and its antenna are at least one inch (2.5 cm) from your body when transmitting . Data operationWhen using any data feature of the radio, with or without an accessory cable, position the radio and its antenna at least one inch (2.5 cm) from the body.Approved AccessoriesFor a list of approved Motorola accessories visit our website at www.mot.com.ELECTROMAGNETIC INTERFERENCE/COMPATIBILITY Note: Nearly every electronic device is susceptible to electromagnetic interference (EMI) if inadequately shielded, designed or otherwise configured for electromagnetic compatibility. FACILITIES To avoid electromagnetic interference and/or compatibility conflicts, turn off your radio in any facility where posted notices instruct you to do so. Hospitals or health care facilities may be using equipment that is sensitive to external RF energy. SAFETY AND GENERAL INFORMATION iv PRELIMINARY AIRCRAFT When instructed to do so, turn off your radio when on board an aircraft. Any use of a radio must be in accordance with applicable regulations per airline crew instructions. MEDICAL DEVICES Pacemakers The Advanced Medical Technology Association recommends that a minimum separation of 6 inches (15 centimeters) be maintained between a handheld wireless radio and a pacemaker.These recommendations are consistent with the in…

HP8901B Modulation Analyzer EXHIBIT 7 FCC ID: AZ489FT4852 RF POWER OUTPUT Pursuant to FCC Rules 2.985 (a) Method of Measurement The RF power output is measured with the value of voltage and current specified in Exhibit 3 as required by 2.983(d) (5). A 50 ohm RF attenuator of proper power rating was used as a load for making these measurements. For Transmitter having an output impedance other than 50 ohm, a suitable matching network is placed between the transmitter and the load. The power measurements are made using a Hewlett Packard series HP 436A power meter and 30 dB attenuator or a HP 437B power meter. AUDIO FREQUENCY RESPONSE Pursuant FCC Rules 2.987 (a) Method of Measurement Operate the transmitter under standard test conditions and monitor the output with a frequency deviation meter or calibrated test receiver. With 1000 Hz sine wave audio input applied through a dummy microphone circuit, adjust the audio input to give 30% of full rated system deviation Maintaining constant deviation, vary the input frequency from 100 to 5000 Hz, and observe the level necessary to maintain a constant 30% modulation. Minimum Standard The audio frequency response shall not vary more than +1 or -3 dB from 300 to 3000 Hz as referenced to 1000 Hz level (with the exception of a permissible 6 dB/octave roll off from 2500 to 3000 Hz) EXHIBIT 7 FCC ID: AZ489FT4852 FCC Limits —Per applicable rule parts. A. 25 to 450 MHz Frequencies between 3 kHz and 15 kHz shall be attenuated greater than the attenuation at 1 kHz by 40 log 10 (f/3) dB. Frequencies above 15 kHz shall be attenuated 28 dB. B. 450 to 866 MHz Frequencies between 3 kHz and 20 kHz shall be attenuated greater than the attenuation at 1 kHz by 60 1og 10 (f/3) dB. Frequencies above 20 kHz shall be attenuated at least 50 dB. MODULATION LIMITING Pursuant FCC Rules 2.987 (a) Method of Measurement The transmitter shall be adjusted for full rated system deviation. Adjust the audio input for 60% of rated system deviation at 1000 Hz. Using this level as a reference (0 dB) vary the audio input level from the reference to a level 20 dB above it for modulation frequencies of 300, 1000 and 3000 Hz. Record the system deviation obtained as a function of the input level. FCC Limits Minimum Standard - The transmitter modulation must not exceed rated system deviation at any audio frequency input or reasonable change in input level. EXHIBIT 7 FCC ID: AZ489FT4852 OCCUPIED BANDWIDTH Pursuant to FCC Rules 2.989 Method of Measurement Data on occupied bandwidth is presented in the form of a spectrum analyzer photograph which illustrates the transmitter sidebands. A photograph is taken of the unmodulated carrier, for reference, to which is superimposed the sideband display generated by modulating the carrier with a 2500 Hz tone at a level 16 dB greater than that required to produce 50 percent modulation. If tone or digital coded squelch is indicated, photographs using both the 2500 Hz tone and the indicated squelch signal are used to modulate the transmitter. During these measurements, the instantaneous Deviation Control is set for a maximum of +2.5 kHz. FCC Limits - Per Applicable Rule Parts. Measured Data: On any frequency removed from the assigned frequency up to 5.625 kHz, the spec is 0 dB. On any frequency removed from the assigned frequency from 5.625 kHz up to and including 12.5 kHz, the spec is at least 7.27(fd- 2.88 kHz) dB down. On any frequency removed from the assigned frequency by more than 12.5 kHz, the spec is at least 50+10log(P) dB (mean output power in watts) or 70 decibels, whichever is the lesser attenuation. RADIATED SPURIOUS EMISSIONS Pursuant to FCC Rules 2.993 Test Site: The site, located at Plantation, Florida in a region which is reasonably free from RF interference and has been approved by the Commission for Spurious Measurements. The equipment is placed on the turntable and then placed in normal operation using the intended power source. A broadband receiving antenna located 15 ft. from the transmitter picks up any signal radiated from the transmitter and its operation accessories. The antenna is adjustable in height and can by horizontally and vertically polarized. A spectrum analyzer covering the necessary frequency range is used to detect and measure any radiation picked up by the antenna. EXHIBIT 7 FCC ID: AZ489FT4852 CONDUCTED SPURIOUS EMISSIONS Pursuant to FCC Rule 2.991 Method of Measurement: The transmitter is terminated into a 50 ohm load and interfaced with a spectrum analyzer which allows the spurious emission level relative to the carrier level to be measured directly. Modulate the transmitter with a 2500 Hz sine wave at an input le…

Measured Conducted RF output 1.00 Watts * Calculated Radiated RF output 575 milliwatts Normal DC Voltage 4.20 Volts Normal DC Curent (GMRS) 760 milliampères Primary Supply Voltage 4.20 Volts RF Conducted output power measured at 4.2 Volts *Calculated Radiated RF output. The conducted power measurements converted to dBm minus the antenna loss, Which is 2.4dB (see exhibit 6A-2) and converted back to watts ERP Example: GMRS conducted RF output = 1.0 Watts 10log(1.0w/1w) =30.0dBm ERP = 30.0dBm-2.4dB=27.6dBm ERP = 10^(27.6/10)= 10^2.5235 = 575 milli watts. The antenna gain (loss) is measured in an anechoic chamber free of outside radiation, refraction, defraction and interference. The anechoic chamber’s path loss = 37.9 dBm. The antenna was placed on an infinite ground plane, and 10dBm was transmitted from the antenna. The receiving spectrum analyzer registered –30.3 dBm. Therefore, the antenna gain = Pr – Pt + Path loss = -30.3 – 10 + 37.9 = -2.4 dB. Antenna performance data over frequency is on the next page.
